Just note. In order to get all 20000watts, you have to use both of the 50A outlets. That has to feed 2- double 50A breakers in a sub panel via 6awg wire. Then from sub panel you feed your main panel to a 100amp breaker via 2awg. This gets you all of the 20000 watts. Using 1- 50A outlet only gets you 12500 watts.
Btw, technically, you could just feed the two 50A outlets to two 50A breakers in the main panel, but then you'd be able to mechanically backfeed power to the utilities. The way tommysteele615 describes it, since the subpanel would be feeding only 1 100A breaker, you can safely make sure that only that breaker or the main breaker is on and not both, using an interlock kit.
Make sure you treat the fuel and turn the fuel switch off to let the generator shut down on its own. That will clear the fuel in the carburetor. Then turn off the power switch. Be blessed and a blessing Amen.
Looking forward to your more in-depth on this beast. I am pretty much sold on the Genmax GM9000iED but this thing is really making me think. I have planned on gettin 2 Genmax and running them in parallel. That would get me by with not much extra. But the WGen20000 would power my house and I have another 50 amp line to help others out. Thank you for all you do!
I’m battling the same dilemma, I am worried about my electronics as I just had to replace a 75in TV that was only a few years old. I’m unsure if it was just a normal failure or caused by the few times we lost power and had back up for an extended period of time. Was just about sold on the GENMAX 9k which matches the Westinghouse I have now but been thinking of upgrading to a larger unit.
I just ran my 5 ton 14seer AC unit with my predator 8750 ran it with no problem. I turned off all the other breakers while we ran the AC. Then when we were satisfied with the temperature we turned it off and ran the other breakers.
I just got this generator delivered on Friday. I have it setup with 2, 50amp inlets--1 for each of my 2 panels. We have 2, 2.5 ton units. I don't know if I'll be trying to run both at the same time though. That 5 ton pulled her right down. Definitely a stout unit.
@Buster Hyman Yes. I was able to power both panels and run both a/c units plus lights/ceiling fan/tv. I want to get some meters to see how much power we're using, but for all intents and purposes, it "powered my house."
@@brucewillis7135 This is the only portable generator that I have seen that puts out more than 50 amps, and that's only because it has 2, 50 amp outlets that put out 50 amps each. I haven't seen any portable generators that provide more than 50 amps from a single outlet, nor have I seen power cables that could handle more than 50 amps, so I don't think that I could fully-power each panel, even with 2 generators. These panels are each 100 amps, and as it is, I feed them 50 amps each. This more than powers anything that we need, short of running the washer, dryer, dishwasher, and heating systems simultaneously.
@brucewillis7135 I suppose if nothing on those panels overlapped, you could use 2 generators. On mine, the downstairs condensing unit is on panel A and the downstairs air handler unit is on panel B. The upstairs system is divided similarly. I was advised by my electrician to power both panels with my one generator.
You will wish to have when the time comes. You’re not buying it due to the gas price; you obtain it because it ensures you the peace of mind for the rest of your family. You can not stop the natural disaster, but you can work really smart to minimize the impact.
It's something like 11hrs on 17gal @ 50% load. However, 50% constant load is *a lot* for this generator. I got this unit a little more than a year ago and had to run it one night. Ran it for about 9hrs on just under a half tank of fuel. It ran a few lights, a tv, and my 2, 2.5 ton hvac units. For about 7hrs of that 9hrs, we were sleeping, so only the hvacs ran.
Hey Gavin, I have this gen hooked up to are house with two 50amp rv cords to run are 5ton geothermal no softstart, well pump for the geo and the frigerator. Only this i dont like about this generator is it only has an 83 amp main breaker for its distribution panel. Which is only good for 19920watts @ 240v. Each 50amp cord is only good for 12000. We can almost kill the gen out if the well and the geo turn on at the same time.
Property 1: FL: The more I watch these videos, the more I like the idea of a generator under $800 and a $200 walmart window AC unit that runs on 110v. (im in FL so not concerned with the high KW for heating). not having natural gas on property is a huge limit locally. Property 2: I have free "dirty" natural gas - in a rural area with mining and frequent power outages for 6h-3d, at least 3 times a year. there we do have freeze warnings. Anyone else running a dirty nat. gas line off a wellhead into one of these ? what, if anything, do you put inline to filter water/etc and regulate pressure?
We need something like this as a backup tothehouse. It is about the same price as a whole house generator but save you about $10 - $15k on the install 👍❤️🙏
Plus you need to get a permit and neighborhood association approval for those you’re talking about this one when you move you could take it with you or sell it Thanks for watching thanks for subscribing👍🏾😊💯
When the powers out all the things needed won't be needed such as permits or neighbors approval or HMO fees everyone will be asking you to hook theres into your for power. That's why I'll never live in those areas. The gen looks great and a great review
That's why I bought this one over a true back-up generator. For $2,500, I had both of my panels wired up, so that's the only cost I'd leave at my house if/when we ever moved since the gen can come with us. Compared to sinking all that cost in a stand-by unit that would probably be left with the house during a move.
Question for you, I am also considering getting this generator but with that 50 amp Inlet isn’t that only capable of moving roughly 12,000W? So do you have some sort of special set up that you’re utilizing the rest of that generator power?
This big generator maintains 60Hz.. perfectly during loads. My 12000 Druamax on propane fluctuates between 58 and 60 while running my 120volt microwave.
I just ordered one of these generators. I would like to have an auto transfer switch. My question is what parts do I need to have this fully installed. A full parts list would be very helpful. Any advice on parts or brands is helpful. Thank you for you time and knowledge.
Definitely less than 5% is acceptable anything more I don’t run it. I think the 9000 will power with the soft start no problem. The thing you have to consider is you never know when the AC is going to kick on, so you might be running the microwave or washer and dryer and then the AC decides to kick on and over load the generator. Thanks for watching thanks for subscribing
Gavin, would a Westinghouse 15kw dual fuel generator be powerful enough to run a house with a 3.5 ton and 2 ton split ac units? Not interested in a stand-by generator because I want the ability to move the generator to different location if the need arises. The 27 kw you tested is out of stock but the smaller duel fuel 15 kw is available. I like the ideal of powering my entire house if that need ever arises. Thanks, Randy
This model actually has less than 5% THD it’s not like the other construction style which has over 25% THD So it actually puts out pretty clean power and it’s pure sine wave
This is one serious machine. It sounds like a municipal power sub-station coming online. Quick question Gavin, do you know if anyone manufactures a "V-TWIN" powered inverter generator? Thanks.
Nice Video. I just purchased this generator and awaiting shipment. I’m looking for a power inlet box but all the highest related wattage I can find is around 12,500 watts. Is your inlet box rated for 28kw or will it be ok to use one rated 12.5kw with this generator?
This was a great video! Learned a lot. Could I install 2 inlet boxes and wire each to a single 200 amp breaker box with each going to a 50 amp generator breakers to utilize the full 20k capability?
I agree with you kind Sir @ time 2:43; where you said, "You don't have to do this". Which is break all the circuits \ in the panel. And it really has never been that; with the larger Generators these days. And even it does not need, or IF you are NO using/or turned off those users; in the large amp users. Which I feel is the best way to transfer in small Generators. So, for with this BIG Generator; NOTHING will happen in 99.9% of the times when you leave the circuits on. And think about this. How many times has lightning killed the power and then it comes back on. So there is NO difference. For most ALL big users; of amps; have electronic protectors; for fast on and off power. This is: in most ALL thermostats and/or the A/C's for many years; to protect A/C's, freezer's, Icebox's and etc! For what it's worth.
I'm new to this generator stuff but have questions. With the Westinghouse 20kw... 1 - 50amp plug is limited to 12000 watts (correct? ) Could you connect both 50 amp from the generator to the gome panel to achieve the full potential of the generator? Would that be considered parallel like with the inverter type generators?
Any idea how many gallons per hour that thing is drinking at anywhere around half load? I may be in a situation where I will not be able to install a whole home permanent generator I found a solution So I might need to rig something like this up to power a rather large home with two air conditioners. One problem we have during hurricanes is typically gas supply. Wondering how many gallons per hour of the same drinks
Yes, you can run 87 octane 10% ethanol with some fuel treatment added especially if you’re going to store it that way but I recommend you to drain the complete tank and carburetor before storing.
When you are at full load, are you using just the 50 amp cord, just wondering how so much can run off it, I currently run a small one then yours and thinking of upgrading currently at 13k but runs the whole house minus AC at once, I can run AC but need to turn off some things dues to surge
But isn't the AC on a 60 amp breaker? Just cause it'll run it doesn't mean it won't damage motor long term. Also 50 amp cord has max wattage of 12.5 kw. I have similar set up.
Gavin, I have truly learned a lot by watching your videos. This was the first time I've seen anyone with solar PV shut off RSD before running this type of test. In other videos, you dont show yourself doing so. Is your PV system grid tied and without batteries? I have a 19.5 system with no batteries. Im considering doing exactly what you have done with interlock, inlet box, and generator for longer outtagr backup. I will use DPU for shorter. Is there any danger of genrator getting back fed if you dont shut off the RSD? Just trying to ID all possible issues. Thank you and keep up the great work.
How is the power coming from this generator compared to an inverter such as the 9000 watt inverters out there? I want to protect my electronics with clean power but would also like to run my AC.
@@GeneratorReviews so the low idle switch is not the same as ECO mode? Or does the sound just because the open air vs enclosed generator? Would you recommend the GENMAX over this for a residential backup generator? A 9000 GENMAX matches the Westinghouse WH7500E in power output that I have now just want cleaner safer power to my TVs and such.
Looking forward to the Easy Start on the AC and a test with a smaller Gen. When running a house, does it have to be an inverter Gen? I got a 8750 watt that’s not an inverter Gen.
This is the first 20000 watt generator I have seen and it's by Westinghouse that is awesome power for your entire house. If you don't mind me asking, what is the financial damage to your wallet? Did you have this running on gasoline or propane?
Thank you for the video Gavin. I just ordered the same machine through Amazon (it hasn't arrived yet). When reading the details more thoroughly, I found that the frequency output is 50Hz instead of 60Hz. Your meter shows 60Hz on the unit connected to the house. Did you have to adjust the run speed and frequency settings to get 60Hz?
The soft start helps to run the central A/C using a generator by lowering the power needed to start the compressor ua-cam.com/video/KjGc7fz3D8c/v-deo.html
This generator has 17 gallons tank with a fuel capacity of 17.17 gallons, the WGen20000 may run for around 11hours at 50% load with a full tank (fuel consumption around 1.56 GPH).
You probably need two generator inputs to your house, as pushing 20Kw through a single NEMA 14-50 is over it’s rated limit. I noticed the generator had two NEMA 14-50 plugs, probably for that reason.
@@GeneratorReviews Awesome video! Thanks for posting! can you explain how (and if) you can run two cords out of the 50 amp outlets into 1 200 amp house panel? Thanks!
@GeneratorReviews Came here to ask the same question. Westinghouse's part number 329908 doesn't help anything. The oem filter has no numbers on it. Just spent 30min at the store with the tech looking around. There's a forum that had a comment where the Fram PH4967 and the WIX 51394XP both fit. The Fram is stubby compared to the oem. Going to look for the WIX next.
@@wow1022 Reason I asked is because I plan to purchase a 15,000/12,500 Generator to run everything possible in my 3,000 sqft home. I also have a 5 ton AC unit but I’ve been told it won’t work because both the AC & handler are both 50 amp breakers and the 50amp generator will not power both??
@@lesruth2756 a 12000/15000 probably won't get the AC started on the 5 ton unit without a soft starter, remember that the breaker protects the circuit and not the load, just because it is 50A circuit doesn't mean it's a 50A load, you need get a clamp meter to see how much current draw your AC and water heater pull, usually they size the AC circuit significantly above the actual load because of start up current and circuit length, my 3 ton unit pulls 12A on a 30A circuit

If a 20,000 watt generator doesn't handle all loads turned on, you have a huge problem with the generator. Just start your generator and turn on the generator breaker after you've let the generator warm up.
Just looked At this generator… You have two 50 amp outlets At 240 volts u only produce 83.33 amps continuous. Different AC and heat pump systems require different amperage…having two 50 amp outlets does not give you a 100 amps continuous.. With one transfer switch and one house breaker panel ..the most continuous amps u can feed that panel is 50 amps. So extra 50 amp plug really not much good unless u run a heavy extension cord into house to plug some 220 volt appliance in to that requires less than 33.3 amps… The Westinghouse 15,0000/12,000 DFc Is a way more cost effective Generator..initial cost ,option run propane , and operating cost in gas run time. Now if they wound make this wgen20000 with one plug that you could get 83.3 amps out off be a lot more useful and practical .
This generator is perfect for what it was intended for, which is construction site, you have electric concrete cutting cement, mixers, chopsaw everything connected to the generator at the same time.
@@GeneratorReviews …now that might be true …but caption says whole house generator kinda implies that it would easily take place of a home standby generator…giving you the full amperage of a 20kw unit home unit.
That generator is super overkill for your house if you can power everything off of a single 50A plug. If you have strip heaters in your air handler as a supplement during cold weather and they kick on, it'll trip that breaker and you'll be powering nothing. You can literally do everything you did here with a 9kw continuous, 12kw peak generator.
If I run my whole house with 7000 watts you can run yours and you neighbors!🤣🤣🤣. Only a difference, mine run at low RPMS, therefore fuel efficiency is better...
I don't recommend thus generator. I bought and after the first time I had to use it, the generator shuts dn randomly. It took more than a month a lot of emails ,phone calls to get a new generator. The customer service is very poor. I don't recommend to buy this generator. Buy something else.
Sounds like you got a bad one. Someone like me who sells hundreds of every generator brand I see a lemon every once in a while. Sorry you had to go through that. I hope they took care of you.
Just note. In order to get all 20000watts, you have to use both of the 50A outlets. That has to feed 2- double 50A breakers in a sub panel via 6awg wire. Then from sub panel you feed your main panel to a 100amp breaker via 2awg. This gets you all of the 20000 watts. Using 1- 50A outlet only gets you 12500 watts.
Is this how you have yours wired up?
If my generator has a 50A and 30A, could I do this with the corresponding 50A/30A breakers in subpanel and 80A in main?
So what you're saying is the 12,500 powered his house. Basically, it did it with one hand behind its back. That what you're saying?
Finally someone presents a solution
Btw, technically, you could just feed the two 50A outlets to two 50A breakers in the main panel, but then you'd be able to mechanically backfeed power to the utilities. The way tommysteele615 describes it, since the subpanel would be feeding only 1 100A breaker, you can safely make sure that only that breaker or the main breaker is on and not both, using an interlock kit.
That generator is a beast. When you install that soft starter it won’t even blink.
Make sure you treat the fuel and turn the fuel switch off to let the generator shut down on its own. That will clear the fuel in the carburetor. Then turn off the power switch. Be blessed and a blessing Amen.
Also a good idea to let it run at idle for 10 min or so after being on a load to let it cool down, then turn off the fuel to bleed the carb.

I have this generator on order. My house is fully electric and uses a lot of power. The 83 amp circuit breaker is the main breaker.
What about part 2 show more of this monster. I sold my Generac 17500 and ordered this generator. Less then 5% THD is a game changer.
I'll never need something like that but that was a great demo! Very entertaining.

That was awesome. What all do I need to run the house? I have a 50 amp plug. Already coming out of my box with a 200 amp.
The very first thing you need to do is install a soft start on your compressor then you’re gonna need a 9000 W generator
I run everything in my home on a 7000/10.5 geni . Including two mini split units
Check out the microair softstart
Question for you, I am also considering getting this generator but with that 50 amp Inlet isn’t that only capable of moving roughly 12,000W? So do you have some sort of special set up that you’re utilizing the rest of that generator power?
12500W on the 50amp inlet box, you can still use the plugs on the generator or wire each leg to its own 50amp plug or two inlet box
This big generator maintains 60Hz.. perfectly during loads. My 12000 Druamax on propane fluctuates between 58 and 60 while running my 120volt microwave.
Time to level up or switch to a brand like Champion that can handle the pressure
The max output in that configuration is going to be 12kw (50amp * 240volts = 12kw)
Thanks for sharing!

Get your Inlet box kit plus lock out kit your 50 amp power cable I would say around 25 feet you’ll be all set.
Would I get two so I can run the full 100 amps?
I want to see the 9000 w gen power the ac with the soft start, or do you need two in parallel, and what about that 23% vs 5% harmonic?
Definitely less than 5% is acceptable anything more I don’t run it. I think the 9000 will power with the soft start no problem. The thing you have to consider is you never know when the AC is going to kick on, so you might be running the microwave or washer and dryer and then the AC decides to kick on and over load the generator.

If you are referring to my post about the 23% harmonics, I found my mistake when I looked it up. THD is 5%.

That’s a good idea. You probably have to talk to your electrician see if that’s possible.
Or run a line to your neighbor so y’all can share the cost of a 3k generator.
I agree with you kind Sir @ time 2:43; where you said, "You don't have to do this". Which is break all the circuits \ in the panel. And it really has never been that; with the larger Generators these days.
And even it does not need, or IF you are NO using/or turned off those users; in the large amp users. Which I feel is the best way to transfer in small Generators.
So, for with this BIG Generator; NOTHING will happen in 99.9% of the times when you leave the circuits on. And think about this. How many times has lightning killed the power and then it comes back on. So there is NO difference. For most ALL big users; of amps; have electronic protectors; for fast on and off power.
This is: in most ALL thermostats and/or the A/C's for many years; to protect A/C's, freezer's, Icebox's and etc! For what it's worth.
I'm new to this generator stuff but have questions.
With the Westinghouse 20kw... 1 - 50amp plug is limited to 12000 watts (correct? )
Could you connect both 50 amp from the generator to the gome panel to achieve the full potential of the generator? Would that be considered parallel like with the inverter type generators?
It would not be paralleling, but that is something you can do
@@GeneratorReviews I appreciate the info. Thanks
Any idea how many gallons per hour that thing is drinking at anywhere around half load? I may be in a situation where I will not be able to install a whole home permanent generator I found a solution So I might need to rig something like this up to power a rather large home with two air conditioners. One problem we have during hurricanes is typically gas supply. Wondering how many gallons per hour of the same drinks
This generator uses an estimated 1.56 GPH (gallon per hour) at a 50% load
What's the specifications for the fuel needed for the generator? Will I do fine on 87 octane 10 percent ethanol
Yes, you can run 87 octane 10% ethanol with some fuel treatment added especially if you’re going to store it that way but I recommend you to drain the complete tank and carburetor before storing.
When you are at full load, are you using just the 50 amp cord, just wondering how so much can run off it, I currently run a small one then yours and thinking of upgrading currently at 13k but runs the whole house minus AC at once, I can run AC but need to turn off some things dues to surge
That was only a quarter of its output. This generator is so powerful
@@GeneratorReviews so you can run all that off one 50 amp cord wow
But isn't the AC on a 60 amp breaker? Just cause it'll run it doesn't mean it won't damage motor long term. Also 50 amp cord has max wattage of 12.5 kw. I have similar set up.
Gavin, I have truly learned a lot by watching your videos. This was the first time I've seen anyone with solar PV shut off RSD before running this type of test. In other videos, you dont show yourself doing so. Is your PV system grid tied and without batteries?
I have a 19.5 system with no batteries. Im considering doing exactly what you have done with interlock, inlet box, and generator for longer outtagr backup. I will use DPU for shorter. Is there any danger of genrator getting back fed if you dont shut off the RSD? Just trying to ID all possible issues. Thank you and keep up the great work.
How is the power coming from this generator compared to an inverter such as the 9000 watt inverters out there? I want to protect my electronics with clean power but would also like to run my AC.
This is a pure sine wave generator but it’s not as quiet as the inverter 9000w because of eco mode
@@GeneratorReviews so the low idle switch is not the same as ECO mode? Or does the sound just because the open air vs enclosed generator? Would you recommend the GENMAX over this for a residential backup generator? A 9000 GENMAX matches the Westinghouse WH7500E in power output that I have now just want cleaner safer power to my TVs and such.
Have you thought of using a soft start or smart start? I hesitate to buy due to bad Amazon reviews.
I do have a soft start installed.

What was the total watts, when everything was on in the house?
I only pulled 7000 W not even close to what this generator can handle I could’ve hooked up another house
Aussie Dave in PA here Gavin,... What Soft Start unit would you recommend ?
I’ll be installing the micro air easy start
@@GeneratorReviews with the soft start installed, will you be be doing the test with one 9000? Genmax or Predator?
@@alejandrocarrillo373 yessir I will definitely be doing that👍🏾
@@GeneratorReviews
Thanks 😏
Can you parallel the 2 50 amps to 1 100 amp for a home?
I really don’t know if you can do that.
What amp breaker did you use in your panel for the generator?
My inlet box is a50a so I used a 50amp breaker.
Looking forward to the Easy Start on the AC and a test with a smaller Gen.
When running a house, does it have to be an inverter Gen? I got a 8750 watt that’s not an inverter Gen.
Hey Robert
I would be very hesitant to run a non-pure sine wave inverter on my house with all of your electronics and computer systems
@@GeneratorReviews is there any way to turn it into a sine wave output?
@@TheSnakeman3 it’s a sine wave power already
@Justin Time you are absolutely right but 90% of modified sine wave power is dirty and will eventually cause more problems than its worth
This is the first 20000 watt generator I have seen and it's by Westinghouse that is awesome power for your entire house. If you don't mind me asking, what is the financial damage to your wallet? Did you have this running on gasoline or propane?
When I bought this one I paid around 3k now it’s doubled in price it’s a gas only Gen
@@GeneratorReviews That is a good price and I just found out they have a sale on models they want to get out the door sometimes.
Turn on stove and oven also
damn, you'd need 2 50A inlets to fully utilize the power out of this generator
Buying this!! What size 50 amp cord do I get? On Amazon all the 50 amp generator cords say max 12500 watts but this is a lot more. Thanks
It has two 50 amp plug
I bought 2, 6 gauge cords from Generac. I wouldn't go cheap on the cables
Thank you for the video Gavin. I just ordered the same machine through Amazon (it hasn't arrived yet). When reading the details more thoroughly, I found that the frequency output is 50Hz instead of 60Hz. Your meter shows 60Hz on the unit connected to the house. Did you have to adjust the run speed and frequency settings to get 60Hz?
It’s 60 Hz don’t worry that was a typo on Amazon
Thank you. I was worried as Amazon wouldn’t cancel. Then more research and found the Operating Manual online. It says 60Hz
Wow! Totally Awesome: Does this run on propane too? How much does one of these Bad Boys go for? Thanks Much!
No gas only! $3700
Thanx nice✅
Welcome 😊
You mention a "soft start" at the beginning of the video. (I may have spelled it wrong) Would you mind explaining what that would be for? Thanks.
The soft start helps to run the central A/C using a generator by lowering the power needed to start the compressor

@@GeneratorReviews Thanks for the helpful link. Just subscribed.
@@rcprod9631 Thanks for the Subscribe and you’re welcome glad to help 👍🏾😊
Hey Gavin, how did the sine wave output look on this generator?
The sine wave looked OK as long as the generator was not in the low idle mode
Could you do a THD test on this generator.
I don’t have that unit anymore
What is 20000 gen fuel usage vs 12500 Westinghouse gen; or know; need extra output?
You have to use the extra 50 amp outlet
How big is the tank and how long can it run on gasoline?
This generator has 17 gallons tank with a fuel capacity of 17.17 gallons, the WGen20000 may run for around 11hours at 50% load with a full tank (fuel consumption around 1.56 GPH).
You probably need two generator inputs to your house, as pushing 20Kw through a single NEMA 14-50 is over it’s rated limit. I noticed the generator had two NEMA 14-50 plugs, probably for that reason.
Yes you’re right.
@@GeneratorReviews Awesome video! Thanks for posting! can you explain how (and if) you can run two cords out of the 50 amp outlets into 1 200 amp house panel? Thanks!
Why do these large generators don't offer tri- fuel options?
I agree!! they should have tri fuel for home backup
I like this machine but at the price why not just get a ganarac stand by?
After installation and permits, I’m pretty sure you would triple the cost of this one
Do you know how much natural gas it uses per day?
This generates gas only
Have you changed the oil yet? What oil filter did you buy?
I can't find the oem filter anywhere
You don’t have to use the oem filter just take it to your auto parts store and find a replacement it’s just an oil filter.
@GeneratorReviews Came here to ask the same question. Westinghouse's part number 329908 doesn't help anything. The oem filter has no numbers on it. Just spent 30min at the store with the tech looking around. There's a forum that had a comment where the Fram PH4967 and the WIX 51394XP both fit. The Fram is stubby compared to the oem. Going to look for the WIX next.
What meters are those that you put on each leg in the diy box?
This is the video I showed how I made it and if you look into the description you’ll find all the links to everything you need on Amazon
@@GeneratorReviews you forgot to post the link😎
Question. How come the 50 amp breaker didn’t trip with the 59 amp start up power draw?
household breakers operate on a time overcurrent curve which is an inverse curve, as current increases above the pickup the trip time decreases
@@wow1022 Reason I asked is because I plan to purchase a 15,000/12,500 Generator to run everything possible in my 3,000 sqft home. I also have a 5 ton AC unit but I’ve been told it won’t work because both the AC & handler are both 50 amp breakers and the 50amp generator will not power both??
It didn’t trip because a 59 amp at 240v is only 29.5 amp on each leg.
@@lesruth2756 a 12000/15000 probably won't get the AC started on the 5 ton unit without a soft starter, remember that the breaker protects the circuit and not the load, just because it is 50A circuit doesn't mean it's a 50A load, you need get a clamp meter to see how much current draw your AC and water heater pull, usually they size the AC circuit significantly above the actual load because of start up current and circuit length, my 3 ton unit pulls 12A on a 30A circuit
@@wow1022 So what about the air handler blower do you think the two can be powered together on this particular generator?
I just hook up the inlet box. But once I turn the breaker on. No power is transferred. Yes the main is off
Make sure all your circuit breakers on this generator are on.
@GeneratorReviews when I flip the circuit on .the volt reader on generator goes blank . And when I flip off it comes back on
Is your ac compressor a single stage?
Yes I believe so
Is your 5ton a heat pump or straight cool
Just a straight cooling no heat pump
if you use one receptacle does that mean you can only get 12,000 watts?
Yes but it can be wired for two
@@GeneratorReviews Awesome video! Thanks for posting! can you explain how (and if) you can run two cords out of the 50 amp outlets into 1 200 amp house panel? Thanks!

@@joeriddell1 I would like to know that answer also.
What 50 amp power cord is this?

What's running watts means?
Running watts means what the generator can handle
Look at all those tandem breakers, my lord is that up to code
SMH
Do you think a West 12000/15000w generator run a 5 ton A/C unit?
Yes it might start it but with a higher THD things will run hotter My computers refrigerators and even the compressor
@@GeneratorReviews Thanks I just concerned about the extra cost for the 20000w unit.
@@donaldjeansonne8667 The 12000/15000 is also 5% THD add that soft start kit and you will be good to go.
How many gorillas does it take to move it it's got to be heavy
540 lbs it’s Heavy
If a 20,000 watt generator doesn't handle all loads turned on, you have a huge problem with the generator. Just start your generator and turn on the generator breaker after you've let the generator warm up.
Just looked At this generator…
You have two 50 amp outlets
At 240 volts u only produce 83.33 amps continuous.
Different AC and heat pump systems require different amperage…having two 50 amp outlets does not give you a 100 amps continuous..
With one transfer switch and one house breaker panel ..the most continuous amps u can feed that panel is 50 amps. So extra 50 amp plug really not much good unless u run a heavy extension cord into house to plug some 220 volt appliance in to that requires less than 33.3 amps…
The Westinghouse 15,0000/12,000 DFc Is a way more cost effective Generator..initial cost ,option run propane , and operating cost in gas run time.
Now if they wound make this wgen20000 with one plug that you could get 83.3 amps out off be a lot more useful and practical .
This generator is perfect for what it was intended for, which is construction site, you have electric concrete cutting cement, mixers, chopsaw everything connected to the generator at the same time.
@@GeneratorReviews …now that might be true …but caption says whole house generator kinda implies that it would easily take place of a home standby generator…giving you the full amperage of a 20kw unit home unit.
You didnt turn any appliances with the AC. A 9500 watts can do that.
With 28,000 W starting I didn’t think I would have to. I could’ve ran my whole house and my RV at the same time.😅
That generator is super overkill for your house if you can power everything off of a single 50A plug. If you have strip heaters in your air handler as a supplement during cold weather and they kick on, it'll trip that breaker and you'll be powering nothing. You can literally do everything you did here with a 9kw continuous, 12kw peak generator.
No longer anywhere
If I run my whole house with 7000 watts you can run yours and you neighbors!🤣🤣🤣. Only a difference, mine run at low RPMS, therefore fuel efficiency is better...
I couldn't have stuff like this am the most worthless guy with mechanical things Too confusing for me.
Lol can’t be that bad!
No longer on Amazon
Electric Direct Generator has them on sale for $3100
I don't recommend thus generator. I bought and after the first time I had to use it, the generator shuts dn randomly. It took more than a month a lot of emails ,phone calls to get a new generator. The customer service is very poor. I don't recommend to buy this generator. Buy something else.
Sounds like you got a bad one. Someone like me who sells hundreds of every generator brand I see a lemon every once in a while.
Sorry you had to go through that. I hope they took care of you.
Is safe to run sensitive electronic like tv, computer, washer & dryer?
Inverters generators are a lot better for sensitive electronics
