Re: Breaker for enclosed trailer?
I wanted to drop in and say thanks again to everybody for your input. I think I finally figured out a good plan of action after reading what you had to say and stopping by an RV Center for further discussion. I've decided against adding DC power since I don't have trailer brakes on this small trailer. I'm planning to use a Square D 60A 2-space Main Lug where I'll put a 30A breaker on one side (back-fed to the 30A Inlet) and a duplex 20A breaker on the other side (the lugs will have a jumper between them so that the 30A can provide power to the 20A leg). Here's a pic I found where somebody did something similar though it looks like they're supplying power direct to the left lug so there's no backfeed. The one thing missing from the above photo is a backfeed breaker retaining kit, which is used to lock down the backfeed breaker to prevent arcing. I'm not sure if Square-D's retainer will work with this panel so I may have to improvise... This panel comes with separate ground/neutral bars which is of course recommended on trailers. I noticed that some main lug panels have tied ground/neutral that can't be separated so you have to watch out for that...938Views0likes0CommentsRe: Breaker for enclosed trailer?
Thanks everybody. If I'm understanding correctly it sounds like back-feeding is pretty common for RVs. I was looking for detailed photos of the Progressive Dynamics panel that was mentioned and found this thread: http://www.classicwinnebagos.com/forum/index.php?topic=5326.0 Looks like it's also basically a back-fed main breaker. I didn't have any luck when I went to a local trailer dealer but I'll go to some RV dealers today to see what they have. Mark938Views0likes0CommentsBreaker for enclosed trailer?
Hi, I think I've reached the end of my Googling skills and would really appreciate your guidance. I am wiring my 6x12 enclosed trailer for a rooftop (13.5k) AC & four duplex outlets that will be used for basic purposes such as charging phones & computers and running some LED puck lights. Currently I don't have any plans for a DC environment. I have a 30 Amp inlet that will be connected mostly to a pair of EU2000i generators and sometimes to a 50 or 30 Amp RV park outlet. My issue relates to finding the best (safest) option for a breaker panel. I am planning to use a 20A breaker for the AC and a single 15A breaker for the outlets. If I use a main lug panel (no main breaker) those two breakers could total 35A and I am concerned that there would be a potential hazard since I'll be using a 30A extension cord as well as 10/2 wire from the inlet to the trailer's breaker. I can't seem to find a 30A main breaker panel and most seem to be 100A or higher... So if I was to install a 100A main breaker I would still have the same issue of potentially sending 35A across my 30A extension cord. Another alternative I've considered is using a 30A breaker on a main lug panel and then back-feeding it in order to create a quasi-main breaker, though this seems to be a controversial method on the internet, and if it's dangerous in any way I'm not interested. Do you know if there is a 30A main breaker available on the market? Is it possibly ok to forgo a main breaker and just use the 20A & 15A breakers? Am I over-thinking this? Thanks in advance, Mark6.3KViews0likes14Comments
