My RV has a single outlet circuit as you describe. My issue is that the GFCI outlet is outside the coach. Can I replace the standard 15 amp breaker with a GFCI breaker and then replace the outside GFCI outlet with a standard one?

Yes you can as long as there’s room in your power center. I believe that a lot of coaches are wired that way.

Quick caveat about resetting GFIC. The in my trailer must have power to it or it will not reset. You instruction to reset any tripped breaker covers this. Not all gfic are like that.

Exactly… which is why I said to reset the circuit breakers first. Thanks for reminding everyone. 😁

Also, on some class A coaches, such as Entegra and others, the GFCIs are located in the main 120v AC breaker panel and not in the 120v AC outlets. They are usually identified with a white trip test button. Again, as Mike says, they only trip halfway. You must turn them off and then on to reset. Also, most Winnebagos have 12v DC resettable breakers on their circuits, not fuses. Be safe out there.

Hi Mike. I think the main DC control panel has 12V breakers. There are a couple inline fuses in the motorhome but there is also a main control panel of (what appears to be) dc push-button breakers in the exterior compartment under the drivers seat and, if I remember right, a second such panel in the chassis battery compartment for chassis 12V features. Maybe the little white looking buttons have fuses underneath them,... but Tiffin calls them breakers. Page 59 https://tiffinmotorhomes.com/uploads/owner-manual/Allegro-Breeze-Manual/Allegro-Breeze-Manual-2019.pdf hints at what is there. This manual is actually from an older model, not the 2019.

I know that high-end RVs can have 12-volt DC breakers instead of fuses, which is also common in the Marine industry. And Tiffin motorhomes are certainly high end. 😁

HI Mike, FWIW our Tiffin Breeze (class A) has 8-10 breakers for 120V circuits and 20+ breakers for DC circuits.

I believe you mean 20+ fuses (not breakers) for 12-volt DC circuits, correct? And you probably only have 1 or 2 GFCI circuits for all 120-volt outlets in your coach. The intermixing of 12-volt DC and 120-volt AC circuits in an RV is another difference between an RV and a bricks and sticks house.
