Will this work for a double-wide trailer or does electric box need upgraded

Will this work for a double-wide trailer or does electric box need upgraded
Asked by: Newtothis
Your question doesn't have enough information to provide an answer. Typically trailers have one service panel per trailer, so the answer is that is depends on the infrastructure and capacity of the trailer panels. You need a qualified electrician to review your site and he/she will be able to tell you.

20000-Watt (LP)/18000-Watt (NG) Air-Cooled Standby Generator with Wi-Fi and Whole House 200 Amp NEMA3 Transfer Switch is rated 4.8 out of 5 by 496.
Rated 5 out of 5 by from Best Investment I have Made in a While We bought a home in an older part of town that has very large mature trees. I noticed that about half the homes in the neighborhood had generators so it made me think we probably should get one. The previous owners had an old portable generator. My wife and I went back and forth on whether to get a portable, partial, or whole house generator. Ultimately we decided on whole house. It was installed in July 2011 and I wondered when or if we would actually use it. Then came Tropical Storm Lee (Labor Day weekend), we lost power on Monday and it was not restored until late Thursday afternoon. I must say the generator has already paid for itself in my opinion, it would not have been any fun to have our food spoil much less be hot with children in our home. The 20kW easily powers our entire home including a 5 ton AC unit, three refrigerators, oven, and we can even wash clothes (with gas dryer). I highly recommend this unit, on its very first service it ran for 73 hours continuously without a single problem.

Rated 5 out of 5 by from good features works as advertised a little cumbersome to setup and program but once complete everything works as it is suppose to . just got it installed and haven;t had to use it yet. looks to me that one needs to make sure to size it wright . most people do not realize the amount of power the average home can consume. and a load management system or load shedding system should be considered . Also something to consider is the price of installation, i/e gas line and electrical connections,

Rated 3 out of 5 by from Ongoing lack of Remote Monitoring in Canada is Ridiculous I bought a 20kW generator in 2013 and the fact that Generac still does not have a cellular or wifi remote monitoring solution is ridiculous (a wifi solution has been underway since 2017with still no definitive date - maybe by the end of 2019). The unit itself runs relatively well, though requires a reasonable amount of servicing, etc. Have had to replace control panel once.

Rated 3 out of 5 by from Bad Control Board on 20KW Generators My generator is on it 3 Control Board in 5 years that I have owned it. Seems like Generac has issues with the Control Boards and they are doing nothing about it. I'm concern that every few years this is going to be a issue. David

Rated 5 out of 5 by from Great It easily can start from my phone, and I get updates on if there is any problems and maintenance is required. It's great. It's a pretty smooth transition to switch from city power to generator power.

Rated 5 out of 5 by from Powerhouse with good looks!!! We were looking for a generator that would take care of our entire home without the need for extension cords and countless gallons of gasoline. This Generac 20KW is well worth the cost. We are secure in knowing that any power interruption will be automatically taken care of whether we are home or not. Our installer, Diversified Electric LLC, of PA did an excellent job and did so while keeping us informed at every step of the process. Excellent communication and knowledge of the product. The Generac 20KW fits very nicely into our existing landscape and looks as if it were always there. The cabinet design enables it to blend in very nicely. The unit runs relatively quiet. It is not very noticeable from within the house while running. It recently went through an exercise cycle while we were entertaining and it was hardly audible from within our home. We are confident that this unit will more than definitely fill our needs.
