- Before you go pulling that NM cable through some smirf-tube underground, watch this video. Conduits installed in underground environments are considered wet, and NM cable IS NOT A WET-rated conductor.

This was a quick and easy little troubleshooting job. The customer called and said they had a circuit that kept tripping everytime their timeclock came on, which controlled their outdoor lighting. So I decided to stop by and check it out.
I found all of the bulbs installed were incandescent candelabras, which can break easily and sometimes show as a short circuit while troubleshooting. I found quite a few bulbs that were bad, so we just took all of them out to see if that would clear the fault. It didn't. We flipped the breaker and it still tripped, with no bulbs in the fixtures. I inspected all of the sockets at each fixture, and there were no visible signs of anything shorted out or melted, so I began to think there may be issues with the wires inside the fixtures.
This is less likely to be the case, but I also noticed no weatherproofing at the base of each fixture so the likelihood of moisture getting into the fixtures was pretty. Upon opening all of the light fixtures I verified that the conductors inside the stone were soaked at every location. The problem with this is that Romex (NM cable) is not rated for wet environments. The insulation around the conductors is not made of a material that is rated to withstand moisture, and over time can break down and cause a short circuit to occur.
This is exactly what happened.

ive been a commercial/industrial electrician for 15+ yrs and a overhead lineman for 5 yrs. i still love watching you teach your techniques because you take pride in your work..keep it up brother God Bless and stay safe
Ya, really took a lot of pride in literally putting tape on a known code violation, collecting money and rolling out so fast he didn’t have time to video the lights working.
I’d really hate to see your level of someone not taking pride in their work.
I can appreciate your sentiment. Dustin is a fantastic electrician however this is by far his worst video and something we’ve all done but should really keep to yourself.
I wish everyone would say God Bless. 🙏
We need more videos of you working on real world shit. I love it
Cement is water permeable, the amount depends on cement mixture, hence it is a wet location when exposed to the ground or outdoor conditions. It does not take high amounts of moisture to damage romex so the small amounts of moisture that make it through the permeable cement can do heavy damage to the insulation.
The real problem with using type NM cable in a situation like this, even if it was for a 12 or 24 volt circuit, is the jacket and inner paper, even though the conductor insulation might be THWN, the paper soaks up water, the outer jacket holds it in, everyone has seen THWN fail eventually because of a scuff in the nylon outer jacket on the conductor after a few years, but that is on a conduit that is more than likely filled with water because of condensation and elevation seepage, now couple that with rotting paper.
Those fixtures were not sealed to the mounting surface. There was plenty of room for water to enter the splice area from rain or pressure washing. Also, there is no way to know if those conduits were continuous between fixtures or were punctured during construction. We have all seen crazy stuff like "direct buried romex".
You can do a neat job of taping if you wrap your tape around a small 1/4" drive socket first and use this "mini roll" that you created to dispense the tape around the conductor tightly. Marine heat shrink tube with sealant is also a decent choice and maybe a braided sleeving for abrasion resistance. I love the 'real world' service calls. It's great content.
I use a short section of heavy gauge wire use a low torque small drill motor to turn it
I’ve taped many wire on service calls where they just need to get it going again. Only some of us will admit it though! Good find
I've been on service calls where it needs fixed NOW and then a date and time will be scheduled for it to be fixed right. Usually within a few days.
There comes a time where you can only do what the customer is willing to pay for. Really sucks when a couple of hours of troubleshooting has been spent to diagnose the problem correctly just to half ass the repair.
Twist the up and apply tape. I for one soldered them and then taped. I noticed the code book is different than when I retired many years ago. Never felt confident in the crimp splices but I saw them hold up in very bad environments. I considered the book as a minimum standard and approached wiring from an engineering standpoint--often better than the code. Engineering was my background.
@@paisleyprince5280 charge for the troubleshooting and say have a nice day call someone else.
So much wasted video on a simple fix
I found the ending of this video to be just as satisfying as if seeing the actual fixture lights working properly! Thanks for the closure! 👍🏼
The one important item that I always do when making up connections in a wet location is to make sure the wire nut is facing up. This prevents any water from pooling inside the wire nut and wire connections. It becomes ‘self-draining’.
You never want to caulk around the base of a vertical fixture, as caulking can also prevent any water that may have gotten inside the fixture and base from draining. Exterior light fixtures such as the ones in the video are not water tight. Rain water will enter via the top finial or around metal to metal joints or glass to metal joints. Also every exterior fixture has rusted rivets holding the lamp sockets or a socket with a rusted center (hot) tab.
Or you could just use the expensive WP wire nuts like an adult. LOL
@@jasonj4865 my thought also. Seems like use of silicon filled wn would have been a good plus up
@@jasonj4865 😭UL listed for damp environments too!
I do irrigation wiring as part of my lawn service. Even with the jelly filled wire nuts, I still point them face up so they can drain.
Yup, that's the rule with moisture: things get wet; the goal is to allow them to dry..
Love your videos... they're not only educational and informational, but entertaining as well. It's nice to see you always referencing code so everyone knows it's not just opinion. Keep em coming! Thanks for all your hard work you put into these videos! 👍
Well, actually there is one good reason to use incandescent bulbs. That is when you need light AND heat.
Such as in incubators or warming cabinets.
Yes gotta keep those chicks warm 🐣
@@electrofrying1685 what led lights are you buying with li-fi?
Or when they are totally enclosed.
Sometimes a good old incandescent is a great value...they just work.
@@heynow7363 incandescent outside is a pain, sodium or mercury fittings however are still great outside
@@darylsavage119 no doubt. I have an incandescent pole light on my corner of house 8 feet or so from corner. Lightning on this iron ore ground 300 feet from distribution lines apparently has blown a hole in 2 plus bulbs so far. I kept the last 2. I like the dual level motion detectors so there is a little light until you trip motion..
I drove ground rods on all four corners of home, attached to slab and specialty construction methods of walls.
I may just need to abandon the dual bright motion and go with a good led fixture. Looks like I need to drive a rod at that light, too. It's the only one on the hill ever affected. Crazy.
You've really stepped up your videos! They are a lot more comprehensive with the code checks and safety checks etc! Great work. Ps thank you soo much for doing service call videos. Theyre inherently more difficult and thus more entertaining.
lol
Seems to me that it would be best to always treat EVERY outdoor electrical component as if they were constantly soaked and use materials and methods appropriate for a wet environment as a normal practice. Yes, that would be overkill in most circumstances but you would never have to worry about anything being not quite enough.
@mariaelisakevin1 What about running a new length of replacement Romex through polyethylene tubing and attaching it to the masonry?
Thanks. I love when you go through the code book. It’s extremely educational.
I've NEVER had a bulb short out. They almost always burn out open.
Same here. Sometimes some flickering if the filament opens up and then moves a bit but I've never seen a broken filament cause a short. Although I once had a short when I tried to unscrew a light bulb on which the glass had separated from the base. As soon as I started turning the glass, poof....
Same. Wouldn't the filament just illuminate or burn up if it shorts? I also believe that most incandescent bulbs have fuses in them (Basically the wires leading up to the filaments are designed to act as fuses in cases of excessive current draw).
I think he was referring to incandescent light bulbs identifying as shorts (continuity) if you don't remove them from the circuit prior to testing-- as opposed to LEDs.
Incandescent are better in wet locations show it as a open circuit from I've heard so far LEDs that are rated for wet locations don't hold up. Maybe they have improved over the years...
Same here. I think Juice might be right. I've messed my words up plenty of times.
Definitely more repair videos like this would be great. I appreciate all you do. Many thanks!
Thank you for the ending, I was very satisfied haha. Keep making these videos I love them, there’s no other channel like you!
Video quality continues to improve! 👏🏼
Appreciate you. 👍
Keep crushing! 👍
More like that, teaching/troubleshooting well appreciated.
Dustin bro,I passed ny journeymans exam today and I wanted to say thank you for your videos you helped me out alot.keep up the good work brother
Congratulations! I wish you a full, and satisfying career sir! Welcome to the fold!
Congratulations!
Congrats, also handymen will now be the bane of your existence.
Congrats dude !!! It’s a rewarding career. I remember my instructor sharing advice with the senior class just before writing our national exam (ie Red Seal in Canada). You might have already heard this from a colleague or instructor. Mine said a newly licensed electrician is at the most dangerous point of his/her career. Newly licensed tend guys put a lot of unnecessary expectAtions on themselves. Remember, you can’t POSSIBLY know everything just because you are now licensed. A license is a minimum standard of independence and competence. Often, a competent decision is one where u decide to admit to yourself that you need to ask a more experienced colleague for guidance because u are not comfortable with the scenario you are in. I’ve been licensed for over 10 years now, and am not afraid to ask a colleague for their opinion. Equally, my opinion is often sought. Keep this advice in mind and you will be fine.
Congrats
Great video Dustin. The basic principle without all the legal bouncing from page to page in the code is - Non metallic sheath cable (Romex) is a "NON Rated" wire. In damp and wet locations, outside, underground, even in conduit, the wire must be "rated" for that use. Example THWN or XHHW (etc) are examples of rated wires for wet locations. I am so glad that you covered the codes from front to back about this. As so many just say, "but it works"...... my answer is "for now". I am sure that service call, the conduit does not go all the way back and the Romex is exposed to the concrete block and that why you could not pull it out. Seen that so many times from illegal work by patio and BBQ builders installing electrical. Frustrating. Home owners going the cheapest route always cost more in the end.
One of your best videos yet. This style is great.
I had a short in my landscape lighting. Took me a while to find the short. It was due to a missing junction box where the wire nuts were just buried in the dirt. Don't ask me who or what they were thinking. While fixing it, I discovered the builder ran NM cable in PVC conduit that's buried 12 inches underground. I decided to replace it all with UF cable. To my surprise, the NM was actually ok even though it was nearly 20 years old. I also replaced the really old HID lamps with some super nice LED lamps. So happy with the upgrades and now my landscape lighting is better than ever.
What is the voltage supplying your landscape lighting?
I like the “get your code book out” pause LOL
great to see another vid man!!!! this is again a super vid. you do a superb job on these
Love Love Love the trouble shooting aspect with this video!! This helps me hone my skills in troubleshooting.. more more of this kind of in the field videos!! Keep up the good work!!
In the house where I grew up from the mid 70's to early 90's, we had tube fluorescents in most rooms. At one point, a red and standard color ring fluorescent were combined to give a more natural light spectrum for one room. We almost never had to replace the fluorescent bulbs.
What I would recommend for stuff like this is liquid electrical tape it's like glue/silicone but electrically rated and if used right waterproof like heatshrink. I get there is no rating, but a layer if followed by regular electrical tape is vise versa, it's just a nice piece of mind.
Good to see you! The video was great in both content and quality.
Regarding the conduit, Ryan Jackson says the conductor is rated for what it is rated for. The conduit doesn't do anything to change what the conductor (or cable) is rated for.
Once again thank you for the great content. I really enjoyed the service call edition with code reference. Take care.
Great video I love seeing the stuff from the field
Filiment is the 'spring' thing. It is held in place by two contact wires which go to the base & foot of the bulb
Of course Dustin knows what a filament is. I think he was speaking on the glass rod ..
@@MrMaxyield no. he wasnt
Filament actually, but I think we got the idea. :)
@@phenry5083 yes he was.
@@xenonram no, he wasn’t.
There's still *one* valid use for incandescent bulbs.. when the heat they give off is actually something worthwhile. EZ-Bake oven for your kid, chicken egg incubator, and maybe for stoplights .. Read something a couple of years ago where a city replaced the bulbs in its traffic lights and had to do an expensive re-engineer because they were getting caked with snow that the bulbs used to melt
Keep up the good work, I'm enjoying all theses videos on the daily
Shout out to this Man paying it forward spreading knowledge to fellas who want to learn or expanding on skills
AS an electrician it is your responsibility to ensure the installation is safe. I agree with all your comments however I would have done an insulation resistance test (I dont know what the regs are in America but if the results show problems with the cables which I suspect they might in that installation. I would have disconnected that circuit and informed the client why it was disconnected and offered to give various quotes for fixing the installation properly. Yes I know they may have to have walls dismantled to achieve the same job or surface conduit etc etc but that is better than water getting back into that circuit and the wall becoming live and someone getting a shock. Awkward situation to be in would like to know your thoughts on this
Would never just “tape” it up where I am in Australia, always perform an IR test and in this instance I would definitely use resin heat shrink on the exposed conductors and then apply silicone inside the conduits and fitting and then outside around the base to completely seal that chamber and keep it free from moisture, like his fault finding methods but his repair work seems very cowboy to me
@@marcgaskett yes, it was so weird to have the guy that says, ‘Get out your code book’ just slap electrical tape on as a fix - where’s that in the NEC?
🤣🤣🤣🤣🤣
@@ScottHz as if you’ve ever opened an NEC
He should have disconnected the circuit as it is unsafe. The circuit breaker was also not a ground fault.
I don't think there's anything you could do to make a conduit outdoors not "wet" water will _always_ get in unless the conduit is fully potted. If air can get in (which it will, eventually), then water will get in via condensation, and then it will accumulate. At least that's my take on it.
But with the right wire, it still works. I've seen plenty of wire running literally under water with no problems.
Water in conduit is usually from air. Condensation.
You're right air has moisture, warm air meets cold air and condensation occurs over time water will buildup if not vented for evaporation. It probably would've been better if the Mason had slightly dome shaped around the pipes allowing the water to escape...
Every piece of conduit in the ground has water in it
Primer, glue, putty
Love your videos man, keep it up
Great video Dustin! I find this helpful thank you!
Don't run romex through ANY conduit. It's incredibly hard to pull this stuff through. Use separate wires-- THHW or whatever.
I had wondered about that, because at my mother in law's house, an electrician had run PVC conduit from the main panel, through the exterior wall of the garage to outside, up along the outside, then connecting back through the attic above the 2nd story.
The family was discussing whether they could use that conduit to wire something through the attic, and the insulation surely looked like NM-B/Romex to me, but everything I kept seeing kept mentioning "no Romex through any conduit" and I kept wondering what was going on.
million dollar home “this guy doesnt wanna pay to bring this up to code” seems typical too much money spent on the yacht and golf clubs
That's how they afford the home. Rich people are misers. Poor people spend money on junk food, liquor and cigarettes.
I mean he said he would have to cut drywall and that might not help much so it could easily be like $5,000 or $10,000 if they have to break up the foundation and repair which for 4 lights it's just not worth it
@@james10739 Replace with some sort of Solar/Battery powered lighting, if the outlet is not needed. Even if wealthy, homeowner's mason could be 2 years out on availability. I know an ornamental iron guy... no business cards, no van graphics.... he works for 5 families only.... in order..... so your project is likely 1-3 years wait. Wealthy people spend on their own stuff. But busting everything up sucks. If the guy that built that outside space made a plan... (I still have the carpenters drawings of my kitchen. I wish his work was as good as his ability to make renderings). A tradesman who assumes wealthy people do not pay big money for their stuff is a handyman. Identifying the short, and making a temp repair is fine, but I would sell client on the proper fix, if they wanted additional outlets, or wiring to a firepit all as part of a deck renovation. And if the guy is selling the house in a year.... "good 'nuff the girls he goes out with" (Yeah, stole that one from AvE.. he can not sue me, without showing his face! )

I really like and appreciate your style and approach to presenting the information in your videos.
Very clear and concise, yet real world with a touch of humor.
Thank you.
You now have a new subscriber.
Good content. Thanks. Love the service calls with explanation.
I like the troubleshooting videos.. hope to see more of these.
I think you mentioned it but some clear silicone around the fixture base may have helped. I really appreciate your videos, I was an electrician over 20 years ago before I got into Healthcare, I still do all my own stuff and here and there for family but have lost a ton along the way.
Best aspect of this channel and your teachings is the Use of the Code Book . That is amazingly good.. affirms what you say and assert with Evidence . Thats what i like to see . Not some bloke talking but Proiving what theyre saying is correct . Cheers mate, keep up the great work .
Great content! Trouble shooting is great for step by step. Keep it up Dustin!
These are my favorite videos along with how to s. Also the way the fixtures are mounted to the pillars is an issue thats probably why its all getting wet. There is no sealant between the base of the fixture and the stone which will let water in.
7:08 - The reason it's ALWAYS the last one you check... is because once you find the problem there's no reason to keep on checking. Its like when you lose your keys or something and you tear the house apart looking for them... you always find them in the last place you look because once you found them you stop looking.
I’ve been saying this for years and never met anyone else who thinks this way!
Its a metaphysical phenomenum- mena- menum- menum
I like it, that's good and so true!
Came to post this and knew it had to already be here…. Well done sir
RIP George Carlin
love the knuckle busters, true working man !!
I never really had anyone teach me how to troubleshoot in the right way, just a lot of error eventually turned into a streak of success. When you understand how the electricity moves, when you see the dumbest little things lead to the trips and the funky voltages, and if you get sent to a lot of troubleshooting calls, eventually all decent electricians will naturally go into doing exactly what he documents in the video. I wish this type pf content was more widely available a few years ago, this is good stuff.
The previous owner of my house installed a TT-30 receptacle with "Romex" on a 20A breaker. Luckily, he ran it in 1 inch PVC. Ripped it all out and ran proper THWN to a new RV panel. The old ground was nice and green.
That may have been compliant.
@@lloydmills9619 Nope. Conduit was underground and NM-B is not rated for "wet" locations. The conductors were also undersized.
So a 30a outlet on a 20a breaker. Not so goodly
@@rbryanhull Not so good for running AC.
@@timgraham7851 Thats pretty normal on an AC. In fact the MOCP is the breaker size. They dont have to atch on an AAC and usually don't. Its common to see #12 on a 30 Amp breaker or #10 on a 50. The breaker only provides short circuit and ground fault protection in those cases.
Thanks for a real world example and your care to check the codes. In my reading of this topic, one of the points brought up was heat dissipation, which is very different when one compares NMWU90 alone vs NMWU90 surrounded by conduit. The extra volume taken up by the cover reduces the volume of air inside the conduit, so the tables for conduit fill would need adjustment. Even though NMWU90 is not designed to be run inside conduit, I would guess that both mechanical and water protection would be better! Around here, inspectors will allow a short run for a few feet, which may help avoid an extra box for transition. The problem in your case was the lack of a plastic bushing and clamp to protect the wires from the sharp edge as they enter each light box.
A plastic bushing for a plastic pipe?
@@electricaf365 if the plastic pipe has a sharp bur-round the edge off and you have a bushing
@@bruceanderson9461 it’s smurf tube bro. There are no sharp edges.
@@electricaf365 something was sharp-maybe you can tell me what damaged the insulation as it is important to this discussion.
The technical terms to your debug approach is Occam's razor followed by binary search problem solving (split in half).
For all those that sat through the video, the answer to the video title is at 7:14 is the fault, and electrical code at 7:40 (note to author, use UA-cam timeline chapters to improve content quality).
Thanks for making the video, I had this wet question buried in my mind for some time.
WONDERFUL! Thank you Dustin!
The ending tho!!!..😂🤣😂🤣 SUPER EPIC!!!!..😂😂🎯💪🏾💯
I use the newer klein hybrids (grey/black handle)....by far my favorite hand tool. The only negative, is the smallest hole size to strip wire, is 16 awg solid.
Agreed, I finally switched to the hybrids and stopped carrying my linesman and croc jrs in my tool pouch. It's so nice to use one tool for multiple uses. and I can comfortably twist 4 12 ga. wires together to place under a wire nut with the hybrids. so not many applications where I miss carrying the linesman now. I used to be so stubborn about using multi tools. I hated the feel of them. But now that I realize how convenient they are, and my tool pouch is much lighter to carry. Wouldn't have it any other way. I still keep the other tools in the truck just in case lol
@@andrewbargo1 exactly. Was so use to my basic strippers, and having to pull out the linemans, back n' forth. I've been using the hybrids for a couple years now.
We call our linemans "the electrician hammer" lmao
Buchanan's became my favorite way to put wires together. Sometimes if there were any chance of moisture I could finish the connection by filling it with silicone. Eliminates that corrosion in joints which can drop voltages and heat up which is not good for compressor motors like outdoor refrigerators. Plus if used correctly they will not looses due to vibration. A good hard crimp on the wires insuring mechanical and electrical connections.
Love your content man!!
I like the way you brought the code book into play while doing the job. Yea going through the code book just doesn’t interpret everything clearly at times. Much appreciated

Great video! Keep doing these troubleshooting videos!
(UK viewer) Cool vid dude. Splitting a circuit mid point is often very time consuming and difficult to do unless you spend the time to measure resistance of conductors and estimate length of run etc using the values and it is at best an estimate but can give you a good starting point. Even harder to do on lighting circuits with switch drops etc and who knows how many JB's tucked away. Luckily you only had 4 points on this one to go through so hitting it one by one proved to be the best method. I do love a bit of fault finding but it can seem daunting when you are trying to work out how the previous installer was running on the day.
I’ll open you up to a really good troubleshooting tip for stuff like this If you want to see if you have a shorted line in the ground or if you want to know if you have to start taking fixtures apart.
If you go to the hardware store and buy one of those rubberized light sockets this design to hang from the ceiling in a wet environment to screw a bulb into, you know the old-school ones And keep it in your toolbox… If you run into a situation like this and you want an easy way to find a short, what you can do is disconnect the hot lead from the breaker and connect one end of the light socket to the breaker and then wirenut The black wire that you removed from the breaker onto the wire coming off of the portable socket. Then screw in a 60 W incandescent bulb, yes it needs to be incandescent for this purpose LED or CFL will not do.
What you are accomplishing by putting the incandescent bulb right at the breaker is basically placing a visiual current limiting resistor at the beginning of the circuit before any short could take place.
If that light comes on, that indicates you have a neutral return path either on the neutral or a ground wire back to the panel in some form or fashion. Because electrical current must return to the source in order to complete the circuit for that light to light up. If none of the other lights on the circuit were lighting up before, but this one lights up when you put it in circuit, then logically that would indicate you have an underground short or a short in the wall somewhere in a junction that’s hidden and you’re going to have to investigate.
hahaha the end was so funny hahaha . dustin your the man
isnt that the best part.. when the lights go on and they all work
Just found the channel and had to sub. I love watching solid tradesmen doing what they do best
I really like that you refer to the code book which many others don't. You're also an excellent teacher.
Thank you!
Ever since I became a 480V member, my muscles have gotten bigger, women are coming up to me and asking me my name, and my hairline has filled in. Thanks, Dustin.
Maybe I should try it. Top of my Head looks like I have the mange.
Butt splices also aren't really great for solid conductors so the tape works.
Love the service call videos!!
More troubleshooting videos please!! Love them
These are awesome videos! I love these service call videos, they help a ton!
If you could also add info about how you bid your jobs or how you determine how much to charge your customers, that would make your awesome videos even more awesome I think.
But other than that, keep up the great work, these videos are really great!
In. All my years, never heard of an incandescent bulb causing a short,
Not from a broken filament. But I've had the glass bulb work loose from the edison base, and if someone rotates it bulb, the two conductors can short.
i have actually had someone tell me they had two high dollar LED bulbs burst into flames, and burn the fixture up
en.wikipedia.org/wiki/Shunt_%28electrical%29
I got my first car for $50, because of a shorted bulb. The left rear running/brake light bulb had shorted between sections. The left turn signals didn't work, if the running lights or headlights were on. Also, you could turn on the running lights, flip the lever for a left turn and play the radio without a key. It was a '61 Ford Galaxy, with a tube radio, so it quickly discharged the battery. My uncle had taken it to the Ford dealership, and they gave up, so he sold the 10 year old car to my dad. He was really pissed off that I repaired it for 29 cents!The short was between two of the support wires, inside the bulb, and the defective bulb was likely installed by the Ford garage since my uncle wasn't mechanically inclined.
Learned a few new things, thank you
The light montage was the best part!
Conduit is wet because of warm, damp air inside the conduit, causing water to condense on the inside of the conduit due to the colder ground (and conduit). Romex also shouldn't be used in conduit because the extra insulation in an enclosed space can overheat.
Things must be different in America, TPS (is that called Romex in the USA?) is fine underground in conduits - it can be rated higher too because the ground is cool and cools the cable.
@@matticussilverman6179 I’m in Canada and only single leads can be pulled in outdoor conduit. From the #0 from the pole underground to a #14 for a 15A 125v circuit, only single sheathed strands are permitted in conduit.
@@markstevens1729 nec in us is same. romex shouldn't be in conduit due to overheating . but in this case with 12 g wire and only 4 lights i can't see it pulling no 20 amps. or 16 amps either at 80%
@@ronblack7870 ... there may be an outlet on that circuit so if part of the branch is #12 then the rest must also be #12.
It's a bitch to pull Romex through conduit if you have any bends. But in this case, it would be a bitch to pull it out to replace it with THHN, like code requires. Hope it never gets inspected!
If I have to tape something up outdoors or where it’s wet I use self amalgamating tape. if it has to be colour indicated I wrap over it.
you have gained another sub... i just watched three of your videos straight through and i enjoyed every little bit... i am a fire alarm service tech and inspector in philadelphia and i can relate. i have some crazy stories of my own.... one had to deal with a short on my LowVotage wire and lights not working on a wing of an apartment complex... :)

Exactly what I would've done.... From start to finish... Very nice. I know I do good work...I go in after other guys to find out where the problems are. You did and explained exactly what I would've done.
Nice work
When you said "Stripper lineman's pliers" the picture that popped in my head... oh gawd.
Putting tape on it definitely seems like a hack, when you know that tape will get inevitably get wet, dry out and fall off and the short will reappear in probably just a few years. You absolutely should've used heat shrinking for a more permanent fix.
Fellow Sparky here. Just ordered my 2020 code book. Long overdue so thank you Dustin.
Hell ya my friend, enjoy reading...lol...though to be honest, you may get more enjoyment out of biting your own arm off 🤣
DO YOU KNOW IDEAL SAYS NOT TO TWIST WIRES WITH PLIERS THIS LETS NUTS COME LOOSE NUT IS TO TWIST
WIRES AT LEAST 3 TURND OF WIRE TO PASS INSPECTION THIS COME FROM SALES REP AND THERE INSTRUCTIONS .
CHIGAGO LICENCED ELECTRIAN 40 YRS Have found many loose nuts on wires were twisted with pliers .
@@richardrussell4288 I don’t get why you’d twist with pliers first, it’s a waste of time, when the wire nuts twist them for you (in addition to your reasoning).
@@richardrussell4288 interesting! So many people twist beforehand with the lineman's pliers. Of course, if you overdo the twisting, it creates metal fatigue and weakens the splice. At the other extreme, I've seen wire nuts that weren't torqued enough to keep them in-place over time. I prefer the wire nuts with two wings which gives you more leverage. Afterwards, I tug on the individual wires to make sure they're not loose. Some people wrap tape over the wire nut, which I think is overkill.
Pretty interesting look at the problem; thanks for sharing!
Great, great and easy to understand video
Incandescent bulbs are especially useful when running a generator or inverter because they create a resistive load on the system and convert noise into heat.
I use an incandescent bulb as a poor man's synce light to sync two generators to run in parallel..
An led build will not do this.
noise into heat? Uhm what?
@@sergeig685 AC Inverters and generators do not usually produce a perfectly clean and smooth sine wave. If you hook up an oscilloscope to the line and neutral, you will typically see "stair-stepping" , "saw teeth" or noise on the curve Putting a restive load on the generator plays the same role as the fuzzy cover on a microphone or the vibration damper between a motor and chassis. Resistance generates heat, be it a light bulb, a toaster or the brakes on your car.
@@946towguy2 ah, you did not mean "noise" literally . Yes, incandescents are far less finicky with irregular or unstable power supplies.
@@sergeig685 What we perceive as sound is oscillations in a medium being picked up by our eardrums. If you converted the oscilloscope output into an audio wave form or connected a speaker coil to the mains you will hear what the ac sounds like. , A true sine wave at 60 hz is just above B1 with 432hz tuning. Impurities in the sine wave will sound like distortion or noise.
Adding a resistive load or a ballast can attenuate some of that noise, while smoothing spikes and dips so that there is less risk to sensitive electronics.
its going through cement regardless its a wet location water goes through cement, UF is not more costly so, they should have just ran UF
uf is more costly than romex.
It’s definitely more costly but still, yes it should be used to stay code compliant.
Water goes through cement?
@@mrseanpride6449 asphinctersayswhat?
@@mrseanpride6449 yes
Well done! Nice walk around the code book!
Great troubleshooting! I appreciate you for sharing.
If you siliconed around the base of the light it would most likely keep the water out. It is most likely where the water is coming in.
Water coming in wasn’t the problem
No matter what you do water will find a way in, not to mention condensation, I know this sounds stupid and it's most likely against code but I always drill small drain holes in my junction boxes, I also always use single conductors suitable for wet locations in conduit
@@gurjindersingh199 and grease all outdoor wire nuts with noalox or dielectric grease.
In 35 years I've never seen an incandescent lamp cause a short, I have had them cause an arc fault. I am completely with you on the superiority of led lighting, but sometimes I wonder how some of your surmises come from.
I agree when a bulb burns out it don't short a short is working problems this guy I would not trust to do any work on my house or garage ...
I had the exact same question. Both sides of the filament have to be attached or there would be no light. Broken filament touches itself can't be a short, it is just simply open.
Haha true I've never seen that either in my 15 years
It's called running up the bill. milking the customer. I only get paid if i'm working and theres no more customers today so I'm gonna stretch this one out.
@@iamthundermug I charge by the job not by the hour you charge by the hour when you don't know what your doing
Great vid bro! Thx!
Not sure if I missed it but main reason why it's frowned upon is because you lose amperage overhead. Conduit, especially EMT, can reflect the heat from high amperage back into the wire, so the 12ga-20a rating is for THHN in conduit when it has room to breathe and cool off. When 12ga Romex is in the wall, the insulation holds in heat like EMT does to regular pull wire.
Free-air THHN can handle at least an extra amp or two when compared to Romex or EMT, but for obvious reasons we don't do that. For heat buildup reasons, we don't do both. EMT or Romex (except when necessary, like in basements where the Romex is exposed in the ceiling joints and it runs down the wall 🧱 to an outlet) (use fittings at BOTH ends of the EMT)
Love the videos. Always helpful especially for a learning apprentice
On the topic of incandescent lighting, what about when you have really old wiring (original wiring in a house built in 72) and LED flickers in every socket, but incandescent works perfectly fine. Any thoughts on the cause? My best guess is voltage or amperage fluctuation within the wiring
Have you checked the voltage? With how little power LEDs use, amperage wouldn't be an issue. I don't know how to test it, but it should be 120ish volts @ 60hz, maybe it's not at 60hz and that's effecting the LEDs. Hopefully somebody with more expertise will chime in.
Also if you have any dimmer switches that are original to the incandescent bulbs that will cause a flicker, they are not rated for LED bulbs
Voltage may be too high.
Great troubleshooting video.
Thank you.
your channel is awesome! that’s the thing with this trade no one will understand it but us electricians.along with continuous learning we got to keep sharing our knowledge it’s always beneficial.
1:05 Googling says either "stem" or "arbor"
"What is it, comment below?" It's called a filament and it's made of tungsten.
He's talking about the post that the filaments hang from.
The tungsten filaments are connected to lead-in or contact wires, that come in through the stem. There are also support wires coming from the stem to support longer filaments. The lead-in wires are often connected to the terminal contacts by fuse lead in wires, most of you can guess what those might be for.
@@SF-tb4kb Even with abuse that won't blow a typical lighting circuit breaker. Those tiny leads inside a bulb would vaporize carrying a 15 amp/115vac (1725 watt) feed if they touched. He's in lala land thinking (saying) they could blow a breaker and not burn up and blow open. Whatever!
@@zacharythebeau163 The posts that hold the filaments, I have always called "stand-offs." There might be a technical name for them, but any time it comes up in conversation (not very often) people know what I mean.
@@zacharythebeau163 it's the Filament Support
Yes to more of these troubleshooting thought process videos...
The part that is holding the two wires that holds the filiment is called a post. Living in Australia with different codes, stranded and solid wire, 240 volts etc. I still find your videos very informative and well put together. By the way ive been an electrician for 65 years.
