1. The philosophy is twofold:
[i] to keep AC, DC, house lights and outboard entirely separated;
[ii] to minimize power when mechanical will cover it. No servos, inverters etc.
Generator is earthed [or watered] via metal strip. Outboard earthing is taken care of by manufacturer.
2. Regs say Gen, Battery and OB must all be outside cabin by at least 1 metre. First two have own storage lockers, with run-off and ventilation. Outboard is covered and secured. Gen only used on open to the sides part of cockpit which has roof. Refuelling by putting on towpath first.
