This stuff is extremely helpful. Thanks to you both!

On our Sabre 34, we have a Westerbeke W27, the house bank will have two Group 31 flooded deep cycles, and the reserve a Group 24.

I'm planning to use 1/0 cable for batteries (I think the current cable is 1 AWG). Runs are short since the battery compartment is adjacent to the engine compartment as is the battery switch.

By the chart, the proper MRBF fuse for 1/0 in engine spaces is 250 amp.

So, first, is 1/0 wire a good choice on this boat (Maine Sail, I think you used 1/0 on an S34 recently, but correct me if I'm wrong)?

Second, is the 250 amp a good choice for MRBF fuse on the 1/0 wire, or should I drop down to 225? And will the 225 or 250 avoid nuisance blows when starting?

Thanks, as always, for the input. I owe you guys, and a lot of others on Sailnet, a cold one.
