Edd you ABSOLUTELY need a fuse or breaker on the alternator output; the size of the over-current protection will depend on the size of the wire, which will in turn depend on the alternator output.
And the over-current protection needs to be within seven inches of where the alternator output connects to either the battery or the main DC bus bar. This is why I suggested in my earlier email for you to get some advice from somebody with ABYC experience… :^) — Fred Fred Street -- Minneapolis S/V Oceanis (1979 C&C Landfall 38) -- on the hard in Bayfield, WI :^( On Jan 30, 2015, at 4:34 PM, Edd Schillay via CnC-List <cnc-list@cnc-list.com> wrote: > Graham, > > This is the switch I’ll be installing: > https://dh778tpvmt77t.cloudfront.net/images/products/8280.jpg > > And yes, I’ll be connecting the alternator to the house bank as well, > not to the starting bank (with an Echo charger between the house and starting > — > http://www.westmarine.com/buy/xantrex--digital-echo-charge-battery-charger--333669) > > For the group: What size wire should I place between the Alternator and > the House Bank?
