Resetable Circuit Breaker
I replaced a thermal 40 AMP circuit breaker with a T Tocas 40 Amp Surface-Mount Circuit Breakers with Manual Reset. Now I can open the circuit to do maintenance and at storage time. Great to know if it is set or open buy glancing at the red control arm. I have recommended this to other RV camper users since it is easy to install and serviceable.

appears to be well made
As usual Amazon delivered this promptly and the piece appears to be well made. It was easy to install. Time will tell if it is water resistant and whether it works as required. Very satisfied so far with product and purchase process.
