120v AC

[Sebas]

I need help for my 120V system on my T4500. The old converter produces about 14V. I choose to replace it with a NOCO smart charger and a fuse box. I have no problem with the 12V now.
I'm actually using the 15A circuit from the old converter. I want to replace the old cable and upgrade to 2 circuits 15A. What type of circuit breaker should I use? I want to keep my 12v system.

Is it better to put a main breaker if I use two circuits?

Show us a picture of what you have, is it an all-in-one unit, or do you have an AC breaker box?

I have to rebuild my system. My DC is done. I am thinking about how to do for the best. Maybe I will use the box of my old converter and use two push button breaker. One for each circuit

You don't need a main breaker. If you feed your unit from a generator, the generator will have a circuit breaker to protect it's outlets. You just have to make sure the wiring external from the generator thru to your new circuit breakers is sized to the generators outlets. If the generator is a standard duplex outlet it will have either 15 or 20 amp rating. If you use 12 awg wire you will be covered.

Same goes for a connection at a trailer park. Use the duplex outlets if you have a 12 awg wire. If you plan on using the 30 amp outlet at a park then you will need 10 awg wire from the park outlet to your new circuit breakers.

For my house I always use 14 AWG for 15 amp circuit. Is it the same for stranded wire ? Why you suggest to use 12 AWG wire ? I know biggest is better but the cost is not the same.

For house wiring use 14 awg or 12 awg for a 15 amp circuit, use 12 awg for a 20 amp circuit. In your situation you are relying on an external circuit breaker to protect the wire feeding your trailer and you may not know what it is (15 or 20 amp). What I am saying is, to make sure your protected use a 12 awg wire.
