Am I wrong in guessing that this refers to campers that have sections that slide out?

One of those breakers might be for the charge line from the chassis alternator to the coach battery, if you have a second battery.

Microwave is always AC, just like your A/C unit. Tele could be AC or DC but wouldn't need 30 amps DC unless it's really old and there's an inverter hidden behind it.

I have an OLD Class C converted from on old Chevy Van. It is small but I am modernizing it a bit. I bought a new power center and my question is...
It comes with TWO DC breakers that can handle 30amps. The rest are all 20.
To me? I am guessing I just ignore those 30amp? I can't imagine what would need a 30amp breaker? I have an air conditioning unit but that only runs on AC power anyway. Anything DC would just be the lights, microwave (maybe), tv and water pump.
The water heater is gas.
