Converter trips breaker

I'm a new owner of a 1979 31' soverign (if you trust the plate on the name plate on the exterior of the trailer) or Excella 500 (if you trust the owners manual) with a rear bath.

Here's the rub: the 120 AC works fine. The DC works off battery w/ no problem. However, when I plug in the (brand new) Intelli-Power Converter, the breaker trips.

I've replaced all the fuses and have ensured there is no reverse polarity.

Any help is greatly appreciated.

Sounds defective. I'd send it back, maybe after trying it with an extension cord and an outlet in the shop.

Thanks for the responses. It turns out that if I by-passed the outlet that was designated for the converter and used an extension cord from another power source that the unit functioned properly.

You have not solved the problem.

You mention fuses and beaker in your original post. If the trailer has a breaker panel and that breaker was what was blowing I would lift the wire off that breaker and put it on another breaker of the same size, have first removed any wire on that breaker. If the breaker holds your original problem was a weak breaker and it should be replaced. If the second breaker blows also there is additional load on that circuit causing the problem. To check this out you will need a clip-on amp meter.

You mentioned fuses. There should be no fuses on the input side of the converter that would hold and still blow the breaker unless the breaker was weak.

Hi Howie-
The outlet I dead-ended was an add-on outlet the PO installed. I think that was putting the additional load on the circuit. I'll test the breaker as you suggest as a double check. Thanks for the info!
