Hello again everyone.
I'm planning the basic electric system using "The Aeroelectric Connection" and the Advisory Circular as my main references. I'm a little fuzzy on how the apply some of the formulae from the AC for wire sizing. I think if you go very strictly by the AC, to run about 55 amps from the battery to the distribution busses I need something like a 2 AWG cable, though most of Mr Knuckolls' drawings run around 4 awg cable.
The big fat cables seem like they'll be a bear to work with. Maybe split the loads up and run several smaller cables through the firewall?
Worst case - highest demand on the power will be close to 55 Amps - if I have all the lights on, pitot heat, lowering the flaps, boost pump on, and transmitting on a com. Battery up front on the firewall.
Opinions on the heavy power lines?
