WFCO Circuit Breakers

I have a combination 30/20 amp breaker in my WFCO 8955 converter. I can't read what brand it is. It seams to be tripping quicker than it used to so I would like to replace it or carry a spare. Rather than removing it and taking it to the store to match it up, can anyone tell me what brand CB I need to buy?

Unless you bought a WFCO Power Center from a vendor who also sold you the breakers, they come without breakers. It's your RV manufacture who installed the breakers. That is why 4 RV's with the same PC could have different brands of breakers installed and why after electrical service, you could now have different brands in your PC.

My WFCO says right on the label what breaker to use, take the front cover off.

I had to replace a breaker in my 7300 Parallax in the 2003 5er. It was not the same size/shape as a typical stick house breaker of the same amps. I had to take it in to do a side by each comparison to get it right. I was lucky to find a store that had that kind, not all do.

If reluctant to take it out and lose all the 120v in the Rv while away-- if it is the fridge or whatever that is a plug-in, you can use an extension cord to the pedestal, and plug the fridge or whatever in directly till you get back.

I matched up some 120VAC Circuit Breakers in my WFCO Power Distribution Center from LOWES...

Thermal breakers do 'wear out', especially when tripped numerous times. The 'thermal' part gets weaker and trips more easily.

You might want to confirm it's the breaker or wiring.

They're fairly standard residential circuit breakers. According to the 8900 series manual from WFCO, the following brands and types are acceptable for main breakers:

Cutler Hammer: BR and C
Thomas Betts: TB or TBBD
ITE/Simens: QP or QT
Square ๐Ÿ˜ง HOM or HOMT
Murray: MP-T or MH-T
General Electric: THQL

In addition, for non-main breakers, Cutler Hammer BRD, BD, and A types are approved.

You may find you need to order a 30/20 combination breaker as that is not a commonly used combo breaker anywhere other than in RVs. An actual electrical supply house would be more likely to carry it than a home improvement store. If you have an empty space, or a single breaker for some other branch, it may be worthwhile to rejigger things so the main breaker is a non-duplex breaker.
