Yes, I know about the ANL fusing delays and ratings. Still, I'd go with a larger one, since I have personally blown a 150A or 250A ANL on my 4-108....can't remember which. No problems since I've started using a 400A ANL over 5 years ago, and my wiring is 2/0.
Look at Maine's circuit diagram. If you're going to use the house batteries for starting, you HAVE to use the BOTH postion (and leave the ON-OFF switch OFF, isolating the start battery).
