Inverter and house batteries electrical plumbing!

The bus now has an official shore power cable hooked up,I went to the local electrical wholesalers and bought 40ft of 6-4 cable ,and the correct plug for the end of it.Total cost about $120. I attached this to a master breaker box with 2x20 amp brakers and 2 x30 amp breakers, the two 30 amp legs feed the inverter,the two 20 amp legs feed oulets in the bays.
The inverter I'm using is a Xantrex RV2012,the inverter is backed up by a bank of 6 golf cart batteries (Trojan T105).
The inverter is wired to a secondary breaker box inside the bus,this breaker has 15amp breakers in it which supply: outlets,lights,fridge,water heater.
I have tested out the system and it works great, the inverter will operate a small flourescant light all the way up to a single rooftop ac.
I bought the optional Inverter remote control panel and it is definately worth it.It mounts inside the bus in the passenger compartment.Makes programming the inverter a breeze.
I'll post pics tomorrow
