Chris,

Replace any incandescent lights with led's.

I deliberately tested the RV by turning on everything. It did cause the 40 amp breaker to trip.

I've never had a repeat.


LED lights are one of the first mods I do on any new RV! Yes, they use MUCH less power. This RV has LED lights.

Just a random occurrence (tripped reset breaker) that has only happened twice in 3 years. I have ordered auto resetting breakers and will replace in all my RVs (an inexpensive and easy switch).

Thanks for the suggestions!
