- This video Is not a tutorial, and I highly recommend having a trained electrician install your transfer switch for you. I am a qualified electrician, that’s why I did my own installation. However, serious injury or death can occur if you don’t know what you’re doing 
I'm not licensed to do this, but I've installed a transfer switch before, installed an outlet for an EV and have done numerous electrical tasks and I understand EVERYTHING in your videos and could do this. Again, I wouldn't because I'm not licensed to do so, but your videos couldn't be more clear. Great job.
I appreciate the kind words!
I needed a unit ua-cam.com/users/postUgkxOTeIs0vv4_9B5hsmnLsk9r930uDQLu_Y that I could store in my home when I wasn't running, so it being light and running on propane were key requirements. I can store the propane tank/bottle outside yet store the generator in my home when it's not in use as I will never put any gas in the engine. It is so light, and on echo mode, which I expect is how it will be used most of the time, it is pretty darned quiet (certainly compared to all the generators I hear in my neighborhood after each power outage).Many of the previous reviews had me concerned that it would be difficult to start on propane, but I have to say, I had absolutely no problem at all. I primed it first using the choke...3 pulls, heard the engine want to start, flipped it to propane, and one more pull and she started. I ran it for 2 hours the first time and plugged it in my fridge. And when I was done, I put the propane tank away and carried the generator to my basement for next time.I could not be happier.
Electrical engineer and PE turned electrician; I too enjoyed the video. I watch a lot of vids like yours to learn from. I have done a few small jobs and learned it is not as easy as it looks.
Under 230.85(3) it says; Other listed Disconnect switches or circuit breakers on the supply side of each service Disconnect that are suitable for use as service equipment and marked as follows: Emergency Disconnect, Not service equipment. Label the transfer switch "Emergency Disconnect / Not Service Equipment" and OK to run 3-wire to existing main panel. Which means you don't have to separate the neutrals from the equipment grounds with separate bus bars.
I'm an electrical engineer and I have a lot of respect for what you guys do. Very nice looking installation too!
i install these everyday. pretty cool to see someone else do it
What kind of company do you work for?
You did a very professional job. Very few people separate grounds and neutrals after first means of disconnect in the area I use to work in.
Thanks for watching! Sadly it is fairly common to see here as well.
It's a code requirement
As an inspector in my county and a electrician really nice job . We always have our neutral and ground separate.
Only one question . Did you had get your meter disconnected?
@mrich7363 thank you. Yep, the Jack was removed at the transformer by the utility.
@@MaynardFamilyHomestead - I have a 20KW unit that I am about to do as much as I can on my own and then have an electrician friend double check my work before we ask for the permit.
What is the wire sizes from generator to ATS and then from meter head to ATS and then from ATS to the load center? Thanks!
Ok, If you are a licensed Journeyman you are an expert and your pay should reflect as much. No one knows it all as our industry continually evolves with new equipment and codes. Knowing how to get the proper information is all you need to do it correctly. You do nice work and as for your wires well, I think we've all been in a crunch and sometimes there's just not enough time to acquire absolute perfection in how we lay the wirers in and bend them at termination. Great job. I still like inhibitor on aluminum as it is a known fact that dissimilar metals will create corrosion, so I think if it will help deter that then why not use it. NEC is minimum requirements, you can go above the required minimum. In this case I do. 43 years at this, Thanks for the video.
Wow, I really appreciate the kind words! A friend once told me the only difference between an apprentice and a journeyman is the journeyman knows how to hide his mistakes! 😜 Thank you for watching.
Suggestion - for a temporary situation or a permanent solution, get a Generlink meter base adaptor. Would recommend the 40 amp unit.
Safe, very easy to use, super easy (5 min.) for the electric company to install.
I have no ties to the company. I bought one and it's a great solution. Using it with my Generac standby genset. Simply plug in the cord when needed, unplug when done.
Thanks very much for you videos is very interesting Im electric mechanics engineer, I have the same generator, Im installed for my self. Thanks very very good, God bless you and your beautiful family.
Nice job two things I would like to input working for FP&L for 38 years you always want to wire brush the AL wire and put an inhibitor on the wire to stop corrosion.
ive read that nowadays the wires are an aluminum alloy and do not require an inhibitor, no?
I just love your utility showed up on time, your inspector showed up on time. Just dreaming of the day that will happen here. Utility shows up hours or even a day late, inspector shows up next day.. sometimes. Such a pain to explain to a customer that as a contractor we have no control over them.
I've been an electrician for 40 years and I enjoyed every minute of your video. Of course everyone has little things they like to do differently but I thought you did an excellent job. I would be curious about your opinion about the use of de-ox on the aluminum connections. I know it is no longer required but I still like to use it. Do you think it still serves a purpose or totally unnecessary?
I really appreciate the kind words! I am definitely not an expert, I’ve only been doing electrical work for 12 or 13 years. I still use it when it’s available, I definitely think it’s not a bad idea. I have even used it on copper in the past. I just see it as a way to make a better connection, not necessarily for oxidation
That's my opinion also. It lubes the point of contact between the set screw and the wire so it doesn't gaul up and makes a tighter connection.
Hi Grag, if you look at a video that Mike Holt posted about the de-ox and why we no longer need to use it on new aluminum wire because of the new aluminum alloy call AA8000 alloy . But on older wire, if you are not replacing it, you still need to use it.
I agree he did a good job, it's not his fault the gen company requires their panel to be the main. This requirement means that unprotected conductors must be on an enclosure with others. Normally the meter should feed a disconnect as the main then feed the subfeeds and the dedicated transfer panel. You would think that a panel with to different power sources woud be required to be the last panel to isolate it from the main.
Excellent question. I use anti oxidant on both cooper and aluminum power connection. An excellent video I might add
Thank you Mr. Maynard, for the tips on the flex on the generator for vibration and the cleaver way you heat the conduit and choke off the oxygen.
You did a very good job, ez to watch! You don’t have a bunch of crap.
I also was waiting to see if you would pick up on moving the ground as first means of disconnect has changed. Great job.
I would probably tighten the wires the same as you.
But if you have a picky inspector, he may want to see your toque wrench. And maybe the Noax.
I myself would just have the toque wrench laying there.
I’m an industrial electrician of 45+ years. And we need new blood like you in the trade.
Again very goof job!!!
wow read some comments and checked in my area i wld have to swap the panel with the ats or run conduit as panel can not be used as a raceway for feeder cables as well as fused and unfused cables can not share same raceway but if you got away with it from your ahj great
Great video. Always good to see how others go about the same task. Insight is everywhere.
I'm an electrician in Canada and would say your methods are almost identical to ours.
I only had the 2 questions. The first was you didn't use de-ox but I saw other comments say it's not necessary there. So that ones answered.
The other was, here, the first point of disconnect for this service would be the meter as it has the grounded neutral. That would mean all subsequent connections would bond to it. So the jumper from the ground rail to the neutral in the transfer switch would be removed. Is that not the case there?
Here our meters don't have a grounded neutral, but that is slowly changing to a similar setup to yours.
Anyway clean work, looks great. Thanks for posting.
Thanks for you video, absolutely enjoyed it. I know to use 3" nipples. 2.5" worked too. Looking for more videos :)
I've done low voltage for years and sometimes have to hook power supplies up to 110. Way on back I did a couple years as an apprentice for industrial and commercial stuff. This actually looks pretty straightforward and I have been trying to decide between a manual setup that pwoers the furnace, well, fridge, and some lights or a whole house setup, but watching this makes me think that going whole house is probably the best way to do this.
Going whole house would be the best way. Why waste time with partial power hook up?
@@brownbee2150 if you have Enough money ,it would be great choice.
Wish I had cutter like that ratchetting one you had back in my days. Great video and nice Installation video. Fm Central Florida.
Thanks! Unfortunately those cutters aren’t the good ones, those are cheap Chinese cutters that cost $30.
Cool, down around Lakeland/ Orlando area? We’re up near the Gainesville area about an hour from Georgia.
A joy to watch. Neat, methodical and not rushed. Taking the proper time to do a job is key in my opinion.
I’ve watched a lot of people doing similar work and it’s frustrating to watch.
Steady wins the race! Thanks 👍 and keep making videos.
Subscribed and liked. 👍
Thank you very much!

Thank you sir
I got a question, here in W.Virginia we are required to use Oxy guard on aluminum wire. I'm no electrician and I know very little about such things. Is aluminum wire prone to shrinkage and/or oxidization? Just asking as I don't know. Very informative video.
Years ago aluminum wire would oxidize and even harden up so it was necessary to use anti-ox compound. Aluminum wire today is actually an aluminum alloy, so it is no longer required. That being said, if I had some I would probably use it just because it doesn’t hurt. I couldn’t find it at the store, so I didn’t worry about it. I also couldn’t find plastic bushings that I needed for the chases, supplies are hard to come by these days.
@@MaynardFamilyHomestead very much helpful, thanks. They don't always tell you this info when buying wire. Thank you.
Hes to stupid to put pentrox on aluminum
Stop doing electrical work
You're still supposed to use penetrox on it. At least in Canada it's in our electrical code.
Looks good thanks for sharing the information I always wondered how these generator set up works. I learned something new today
There’s a naked to the eye film on the aluminum conductor. Always wire brush than add anti-oxidation lube before terminating. Nice job
Most cable manufacturers do not recommend brushing cables
I keep getting anxious he's going to snap the lugs with that "torque" wrench lol. Looks like a good install.
😎 Thanks for watching!
I thought Should be Connecting at the End job first and then at the Power source. But I'm just a regular handyman 😊
That’s only if you want a long happy life. 😜
Very good as I am prepping for a new gen and xfer panel install. Thank you!
Thanks for watching!
As a master electrician … in my area. Not using plastic bushings on those pvc rigid fittings would absolutely fail an inspection. Also the cold water bond, as well as grounding electrodes would also have to be relocated continuously to the new first means of disconnect. Besides that. Nice looking work :)
I think most will agree the pvc fitting alone provides equivalent protection.
352.46 Bushings. Where a conduit enters a box, fitting, or other enclosure, a bushing or adapter shall be provided to protect the wire from abrasion unless the box, fitting, or enclosure design provides equivalent protection.
@@jbar6618 Where raceways contain conductors 4 AWG and larger, the conductors must be protected from abrasion during and after installation by a fitting that provides a smooth, rounded insulating surface, such as an insulating bushing [300.4(F)]. For IMC and RMC, a metal or plastic bushing must be installed on conduit threads at terminations, regardless of conductor size, in accordance with 300.4(F)
In my area, no inspectors agree with your statement. It is a requirement and will fail every time in Colorado
@@jbar6618 PVC or not you still need one.
Cold water bond can go in the panel inside the house. Also he's in an area where the GEC is ran into the meter base in that 1/2" PVC conduit, so there should be no neutral to grounding bonding anywhere else on the premises. Multiple neutral to ground connections on one service is a bad idea. Pick one spot and bond neutral to ground there. In the meter can is safer since the meter box is sealed, and discourages tampering with the GEC and it's connection.
@@brnmcc01 correct. The GEC is in the meter can. Everything should be separated after that , which it is not. Good eye
Grettings from Bogota Colombia South america, great job.
One recommendation, don’t make your tie ins until all wires are ran, would make for an easier installation. (Pulling wires, etc.)
Nice clean wire runs and install.
Thank you!
Forgot the bushings. You also can not run service conductors and feeders in the same raceway. Besides that great video. Thanks for sharing.
or not use penetrox on al cable.
@@keything8487 That's not actually in the NEC anymore although some jurisdictions still require it.
@@SeanLeonDrumz here in central Florida they do
It’s a municipality thing, not a NEC code.
Great job. GE electrical field engineer, retired.
Thanks!
NEC 230.7 states that service conductors "shall not" be installed in the same raceway or cable with feeder or branch circuit conductors! Needs a separate conduit from the meter to the transfer switch to route the "service conductors" (non-fused) and a different conduit routing the "feeder conductors" (fused) from the panel to the transfer switch.
Ain't nobody got time for that.
Exactly
Nice Videos Friend i watched them both and you Did a Very Good Job thanks for sharing a Bit of your knowledge. 👍🏻⚡
Thank you for watching and the kind words!
A few observations:
1. Can you legally use the old Main Service Disconnect panel as the raceway from the meter to the transfer switch - and still use the disconnect as a sub? Didn't think that was allowed.
2. BECAUSE you used the panel as a raceway, was the 2.5" nipple big enough for all the conductors, code-wise? You had to really fight to get the conductors in there.
3. The nipple is also missing a bushing, which could be more of an issue, if the possible overfill of the nipple causes the conductors to rub or push against the edge.
4. Does code in your area require you to relocate your grounding conductor to the transfer switch, since that's what the meter is feeding now?
5. From a best practices standpoint, you should tighten-loosen-tighten-wiggle-tighten the conductors under the lugs, just to make sure the lugs have dug in deep enough into the strands to not come loose in a year or two of expanding and contracting with the heat - reduces the chances of loose-arcing later on.
6. Definitely buy yourself a good, durable torque wrench. If you ever had an issue with fire due to arcing in any of the panels, including the load side of the meter, the one thing that could de-rail a claim payment from the insurance company is whether the lugs were tightened with a torque wrench or not. Might sound trivial, but I'm not joking. The torque settings are usually printed on the assembly, you set the torque wrench and tighten until you hear one click on the wrench. This is also why the tighten-loosen-tighten-wiggle-tighten practice can be so important. Any blame the insurance company can lay at your feet to not pay out a claim, they will do it every. single. time. Protect yourself, definitely get a torque wrench. I only say this because you did the work yourself.
These are all technical observations, local codes can vary, which is why I asked questions, as opposed to declaring something HAS to be a certain way. But aside from that, the work was clean, you definitely got a workout in with those conductors, but overall a nice job. Good video.
Perfect and we'll said.🤙🤙🤙
Unfused conductors aren’t allowed in the same raceway as fused conductors in NC at least. Unless you can create enough space for no contact (very tough to do. Had a county inspector watch me struggle and fail. Had to enter through a new raceway. Passed inspection the next day).
@@hhuucckk Right, and the (sub)panel is now considered a raceway between the meter box and the transfer switch. You can kill power to the sub at the transfer switch, but the meter wires stay on until the meter is pulled or power is killed at the pole. That's what I thought too, the metered lines would still be hot in the raceway, you could still get inductive current. Wire separation can be attempted, I've even seen people make wire separators that can fit into nipples to keep wires off of each other, but there's no way he could do that with a full nipple like that 2.5". Even linear ones would take up quite a bit of space in the bottom of the sub, and get a bit cumbersome just with the number and size of the conductors in there.
If anyone is interested, for Canada the answers would be.
1. No
2. Yes
3. Bushing not needed (but service bonding requirements most likely not met)
4. Yes
He should've also use no locks or some type of anti-oxidation lubricant on all those aluminum wire terminations!!! On service equipment I use it on all terminations aluminum or copper...
The conduit wire fill exceeds NEC standards. You are also missing bushings and antioxidant compound on aluminum terminals. I would have recommended the use of a torque wrench. NEC also requires the ground to be relocated to the transfer switch enclosure. Other than the NEC violations, good video.
This is why I love You Tube! By installing this on You Tube you opened yourself up to a lot of criticism but I thought the video was excellent! While watching your video, I had the Generac manual opened on my computer in another "window" and went back and forth to follow your install. Although my install will be a little different coming from a 200amp service with breakers, the concept is basically the same. I'm getting ready to build a new home in NW FL and have ordered a 24kw Generac and was interested how the new ones were installed. I installed a Generac Guardian at my other house in 2006 and had to separate each circuit I wanted emergency power from the panel to the transfer switch. Talk about a lot of wiring/nuts. Anyway, excellent job!!!
Wow, I really appreciate the kind words! Yeah I have second-guessed myself a few times on whether it was a good idea LOL! Oh that’s electricians always think we know the best way of doing things, and are probably some of the most arrogant people on earth LOL! Good luck on your install buddy, and thanks for watching our video
Dan, why on earth did you buy such a massive unit?! Bigger is not better. I've lived in Florida my entire life as a small engine mechanic and have personally been without power for 3 months during the summer, and I would never recommend such a huge unit to an average homeowner. The fuel cost is outrageous for large units. If you are running propane with buried tank, you have less than 7 days worth of fuel. And you cant buy any more, in Florida, during a hurricane, for at least 3 weeks. The entire state sells out of propane for about 3 weeks at a time. If its a long extended outage, you will basically get 5-7 days worth of electricity, and then no more electricity after that until the power comes back on. The sweet spot for an average house is about 14K watt generator for a hole home , and about a 5000 watt generator if you use a portable with window AC units.
@@bubbatime Hey Scott, NG generator and originally going with a 22kw but the 24k was only $300.00 more. In NW Fl, we have lost power to many times to count due to hurricanes and tropical storms. Can't beat a Generac!!!!
@@MaynardFamilyHomestead
I don't think it's arrogance (okay, maybe a FEW of them), as much as experienced electricians have already made the mistakes and learned from them. I asked a bunch of questions in my comment, because you may have different regs to comply with in your state, compared to others, and I didn't want to assume anything. But anytime I can help someone (like the "best practices" I mentioned in my comment, about the lugs and torque wrench) with something I've learned from years of work and fails, I'll help.
@@MaynardFamilyHomestead you said a mouthful and correctly so. Thanks for the detail and learning experience.
What happened that they did not put the anty oxidant compound on the aluminum cable and did not put the plastic bushing on the connector, nor did they give torque to the terminal screws.👎
As a mechanic, I use torque wrenches frequently, and have noticed torque specs for terminal fasteners. Are these commonly torqued in the field?
Technically they are supposed to be per the NEC. It generally only happens in commercial work though from what I’ve seen. I know a lot of electricians and I think only one has a torque wrench.
110.14(D) Terminal Connection Torque. Tightening torque values for terminal connections shall be as indicated on equipment or in installation instructions provided by the manufacturer. An approved means shall be used to achieve the indicated torque value.
I don"t understand why no compound was used on terminal connections. It looks like aluminum wire.
Having installed service entrance wires and using a torque wrench, I can tell you, you have to tighten them down more than you would think otherwise. I had the panel the house came with fail due to loose connections and I did the install/work on the replacement service panel. It’ll be more important the higher a houses load is. I foresee lots of houses having problems after one electrifies and starts adding more heavy loads like car charging. All my problems manifested after electrifying the house away from gas.
Great job on the install man. May I suggest a torque wrench for those main lugs 250 ft lbs per manufacturer. You stripped the hell out of that neutral lug, but it happens when you’re trying to get her done.
Being an electrican in Australia I found this very interesting and educational. Thank you for sharing.

It is not required by NEC unless required by the equipment manufacturer.
This video caused me to google "who do people grunt when doing something heavy".. but even google didn't know it
One of life’s great mysteries.
Dude thank u. I been doing commercial work most of my life. Shopping centers pretty much. But I've now started my own business n this video helped me sooooo much, especially on the wire for controls... Thanks my guy u saved the day for this man!! I owe u
Thank you sir, I greatly appreciate it! I’m glad to be of help. I was actually a commercial guy myself I never did a ton of residential stuff. I did do a lot of service on generators but only did a couple installs prior. If I can do it you can definitely do it. It’s not as fun as MC cable and EMT, but it’s very easy.
Watching your video I also got a concert from the black crow’s
Hahaha they are so annoying!
Great work. I always get a kick out of the fact that the wire cutters are purpose-built and nice and the wire gets skinned with a utility knife. They make a stripper for that, but nobody uses it.
Hi Im in Canada in the trade 40 years and would never not use de-ox on aluminum and you showed us how much fog and moisture there was in the air ,Just something to think about also you should be using a torque wrench and going to the specks with aluminum ,just trying to help you Nice Job
Wow dude. I've been installing these for a few months now. On a crew. I normally set up the generator pad and the gas. But now cause of your video I understand the transfer switch.
Awesome, glad it was helpful!

Funny how you have him stand clear. Not gonna lie I’m scared of house panels. Had one blow up in my face. I work in a power plant wear it’s safer. 😂
Lol I’m used to the big commercial panels. I had an arc blast from a residential panel as well, was blind for 5-10 mins and burnt my hair and eyebrows. Scared me hood!
It’s funny but true, power plants are probably a lot safer! 😂
My main 150amp panel is in my basement. What is the best place to install the automatic transfer switch? I'm debating on getting a Kohler 20k RCA and not sure where to place ATS inside or outside the home.. Also is OnCue worth it and don't they make a wireless kit so one doesn't need to use a cat 5 ethernet cable? Thanks😊 My gas meter is on opposite side of my house to where the electric meter is.

@@rossradford5767 Sure, He is jamming in six 4/0 AL conductors in a 2" nipple and this is a code violation. Also, he didn't use penatrox on the terminations. Electricity is not a hobby.

I enjoyed watching this installation. I have one question: are you supposed to install 2 different power sources through the same conduit?
Surprised Power man did not wear leather gloves to remove meter. Nice catch on the bonding in second panel. Thanks for sharing.
Thanks for watching, and for the kind comment!
No arc/flash if the breaker panel inside is turned off as there is no current flowing to interrupt.
@@girlmastergeneral You need a lot more than leather gloves to protect from arc flash!
I didn't hear or see any reference to wire gages to use other than the1810 sprinkler wire. Enjoyed your videos !!
Thanks for watching! I used 4/0 aluminum for the main 200a service feeders, and 2-2-4-6 aluminum for the generator feeders.
4:45 doesn't the piece of horizontal conduit going into the panel on the far right need a plastic insulating bushing, or is it ok with out one because its pvc?
Good catch! Any PVC MA 1 1/4” and larger is supposed to have a bushing. I just couldn’t find any in 4 different stores I went to. Material shortages are a thing right now in Florida.
I was surprised you didn't have another bonding conductor in that PVC pipe from meter to Transfer switch but I guess it don't matter seeings how the neutral is grounded in the transfer switch
We're having this same exact generator installed. I didn't get to follow the electricians when they installed the electricals but this is very interesting and educational. Thank you so much for sharing! Now we're waiting on the Gas company to hook up the gas lines. Then the sales guy is supposed to give us a tutorial and demo.

Thank you!
I enjoyed your two videos on installing and wiring a generator and transfer switch. I am sure this has helped someone.
Thanks, I hope so!
@@MaynardFamilyHomestead I know it helped me. I am not an electrician but I am a DIY guy. I know enough to do this but I don't understand why the ground and common have to be separated at the second box. Not sure why but will make sure I do it. If you get time please explain. Thanks again.
@@happycamper6418 That is a great question. Your neutral is your path back to the source (transformer) for any unbalanced current. The ground wire in your house is a safety wire that will cause your breaker to trip should an energized wire touch something it shouldn’t. They are bonded at the first means of disconnect because that is the point where it goes back to the transformer. The ground rod is a safety as well, allowing current to get back to the transformer a secondary way if need be. If your neutrals and grounds are bonded everywhere it’s no different than if you were to touch the ground on a plug to the neutral, it would induce voltage on your devices and possibly cause electrocution. The goal is to never have any current on the ground wire. And if it does, it will automatically trip your breaker.
I just noticed you used Aluminum wire without anti oxide lube on the lug ends. Its code for NEC and most counties I know of. The job may have been a little easier with smaller copper wire. The VIDEO WAS AWESOME though. Amazed that the power company came to pull the meter. The middle box was your outside mains?
Correct, that’s my existing main panel. I didn’t want to work it hot, so I requested the power company disconnect. It worked out great
wow i dont feel like doing the math but i wonder if that coupling is overfilled. that was a tight fit none the less. i might have spent the few extra $$ and just used another 1 lol
I don’t know the code very well. But I think anything less than like 2 in isn’t considered conduit. So it’s not subject to conduit fill tables.
@@johnsandlinjr yes but there is fill requirements for couplings and nipples it's more than conduit but I think cramming all those conductors in might be a violation lol
@@wizard3z868 admittedly it was a little tighter than I would have done, but maybe not an actual violation lol
You can fill up too 60% of a nipple.
It does meet code barely but it does, I still would have done 2 for working purpose
Did you go back and add the 2" plastic bushing to the 2" ta in the transfer switch can? You used bushings everywhere else. Otherwise good job. I also still use De-ox for safety.
That coupling is way over filled and working without safety precautions on the street side is not helpful for folks wanting guidance. It’s not just a matter of making terminations, it’s working safely and up to code that really matters. Apologies for the harshness but that’s how I see it. Nice job on separating the neutral and grounds.
Thanks for watching, no worries. It was only a tight fit because I made the connections on the first wires without running them all through the nipple first. According to my fill calculations, at 60% fill for nipples I am within the NEC perimeters. If I were doing it for someone else I would probably LB out the bottom of the meter can and over to the transfer switch so my wires aren’t traveling through the sub panel. That being said, I’m not sure I follow you on the work safety, the jack was pulled at the transformer so everything was dead.
Nipple under 24" an under can be filled like that but you can't feed through your panel like that. It's not allowed.
@@emissary44 it's about having fused and non fused in the same raceway, it presents a maintenance danger and if a wire was to be damaged by let's say a nail from Fairless siding it could energize what should be a disconnected portion... The code it about safety not about if it works. Also a bushing would be nice on that nipple.

I didn't see you check with a meter to insure the line had indeed been disconnected and deenergized. I would have used anti-corrosion paste (whether required or not), as previously stated by others, it helps reduce gaulling. Also, all lugs should have been torqued to specification.
Not a huge deal in my book, however, I don’t think feeders can be in the same raceway as service conductors per the NEC.
Yeah you might be right, I would have to look in my code book on that I don’t remember offhand. I want to think it’s not considered a raceway being that short, it’s just a nipple. That changes the fill capacity as well. I will have to go look that up!
Yeah I was told I couldn’t use it as a raceway either and it’s just a offset nipple
Your inspector may let you slide a pice of seal tight over the line side to get it through the panel. Good luck.
@@MaynardFamilyHomestead you are correct you can't run unfused conductors in the same conduit with fused conductors. You also can't you the panel as a raceway to get to the ATS. If someone turns off the ATS main and thinks the power is off and drills a hole in the panel and cuts one of those meter wires he could kill himself. Not good to show that.
That would have failed here in ky.
any reason you didn't use dioxide type solution for the connections on the aluminum?
I didn’t have any, and the store was out. It’s actually not required anymore on the new aluminum alloy. It doesn’t oxidize like the old stuff.
thanks for the info bro
Are you allowed to use that middle panel as a raceway for the meter to ATS boxes?
Technically no, I was able to obtain special permission from my AHJ since it is existing and I was on a time crunch to get the power back on for my family.
@@MaynardFamilyHomestead But in normal new builds you can't right?
@@jeepxj That is correct. You would want to get two conduit bodies and a piece of pipe, and come out of the bottom of the meter can and over to the bottom of the transfer switch.
@@MaynardFamilyHomestead or a gutter right? then nipple back the ats output.
Article 312.8 I believe allows it
N btw it looked great buddy!!
Thank you!
Wondering about conduit fill between the generator and main breaker panel? Seems like there's too many for the conduit size?
Less than 24”. Stuff it as full as you can
@@MrSamsamsammy There are other issues there, still. But even code not withstanding, if you're cramming the wires in to get them through.. It might be too full xD
@@MrSamsamsammy Maybe it's jurisdictional but where I live filling a conduit more then 80% full requires derating all conductors. Doesn't matter about length, 1 inch, 1 foot. Over 80% it's a derate. Only exception in residential is when conductors pass through a hole in a stud, you can fill the hole as long as the cables seperate on either side of the stud. That's because a couple 15 amp runs won't generate that much heat under load. and either side the stud cavity offers enough air to keep conductors cool. Same conductors in conduit, the 80% rule applies.
you are not supposed to have protected and unprotected leads running through the same raceway IE; the 2 inch conduit on the right
I am not an electrician, but I love electric and am not scared to work with it. Great video and great install!! I assume you have a sub panel in the basement or somewhere inside the house that you have the rest of the breakers for the house. Well done!
First means of disconnect. All newer meters /new code. U have to have an outside disconnect for fire dept. transfer switch is also a disconnect, meaning if u didn’t have a disconnect before u have to separate your neutrals and grounds.
@@shawnfschooleyjr6592 Re: Disconnect -- Only if the 2020 code has been adopted by the Jurisdiction -- 2017 Code does not have 230.85.
Thanks. Great video.
It looks like he’s missing a bushing there🤣
230.7. this wouldn't pass inspection
Great video
Been waiting for this video!! I'll be doing my own 24kw generac install very soon and this helped me tremendously!! Thanks for the great video, us DIY guys and gals really appreciate it!
Awesome, thanks for watching!
if your doing a similar install use 2 couplings instead of all that fill in just the one lol never mind Floyd Maronge

@@wizard3z868 ... part of the answer is you should never modify anything that is UL listed. That would include drilling holes. This is why there are so many pre-punched locations in the cabinet.
I'm wondering why no anti-ox compound on the aluminum wire? Its required in our area and thought to be required nation wide. Nice job.
Thanks! Yeah I normally use it but at the time of this install it was impossible to find. Same with plastic bushings. Covid really jacked up the supply chain. It’s not required here anymore because the wire is an alloy and not regular aluminum. Thanks for watching!
I appreciate the video in step by step detail along with dos and donts. Really helped me with install. Good Job Maynard Family!!!!
Thanks for watching! God bless
He should’ve did a talk through with the walk through I don’t know where you heard step-by-step instructions but OK😂
Super cool just the meter some electrician will take off the meter reader live and them work
Is there any max fill rate for the pvc, when used like this?
It's America so probably not.
Being a European myself I find it cringe af seeing it all packed like this gives me chills of a fire or something. I would have at least put another conduet from mains going to the top of the boxes rather than route it through bottom of both boxes just for aesthetics, simplicity and safety. Way too much in one condu.
@@tdkyt46 Two things come to mind, 1). it's a very short run, only a few inches, and 2). at any time only half the wires could have current because of the disconnect switch. Might not meet code but in reality I'd guess the danger factor is zero.
Keith R.... yes. NEC chapter 9 table 1 has Information for calculating the inside diameter for various conduit types and sizes and wire outside diameter for the various wires/insulation. Use this if you are putting different sizes in the same conduit.
NEC annex C (also back of book) has charts for various conduits and wire typed/sized. ie. No. 12 THHN in a one inch PVC schedule 40 is 25 wires (nec page 70-791).
Hope that gets you started.
@@JRP3 you put two cond sections together there. Ch 9 table 1 is for how many wires you can fit. And 310.14/15 wire capacity and correction factors.
Hiciste buen trabajo!!!... Felicidades!!!... gracias!!!...✌️👍🙏
Nice work. I just retired as a master in Michigan and I can tell you that without no lox on the aluminum wires you would get a violation! ,
From experience I can tell you using copper wire for jumpers would have made your life much easier.
Also when the unit is so close I would go entire distance to generator in flex PVC approved for direct burial..
It seems you feed generator with no 2 wire but used 2 auot for jumpers.
2/0 is a feed and the number #2 is a feed so im not sure what you a referring to
NO lox is the least of my worries. that conduit is overfilled, no bushings on nipples, and improper grounding/bonding.
Nolox isn't required on today's aluminum conductors as for they are not solid aluminum but an alloy.
@@tedcatino5593 100% inspectors still cry about it though.
No lox is not required by code or the Switch MFG or the wire MFG.
Average Joe that is NOT an electrician this set up would probably cost them close to $9,000 bucks... I just went with a nice portable generator and a Reliance manual 8 circuit transfer switch for less than $1,000 to power important circuits. Keep a small portable or even window a/c UNIT on hand for power failures during summer. Plenty of power to keep lights and 3 fridge/freezers running and A/C if needed. In an emergency no need to power entire house.
You are correct sir. It actually would cost more depending on labor costs. That’s what we used for the last 10+ years and it did just fine.
amazing work, my only question. did an inspector ask you to install a second conduit fitting to pass the wires? up here we need an inch or so of free space
Yes,. Four 4/0 alum , two 2/0 alum and 1 ground wire is too much for 2.5" PVC conduit.
why did you have to separate the ground and neutral bars in the middle panel?
Always a pleasure to watch an expert tradesman do an installation. Always a chance to learn.
I appreciate you watching. I wouldn’t consider myself an expert, but I appreciate the kind words!
Expert? He has six 4/0 aluminum conductors jammed in a 2" nipple. he's over the allowable percentage of conduit fill.
@@rc6147 Thanks. He says so in the Chase section.
Thanks for sharing your install!
Thanks for watching!
Its good to see that some of us electricians are still working before and during the sunrise..
