This battery switch and circuit breaker panel has Mini Dual Circuit Plus battery switch designed for a single engine dual battery application where one battery is reserved for starting. It then has a main 100 Amp rocker circuit breaker intended as a feed to athe boats main breaker panel, and three 15 Amp push button breakers which are wired for 24 hr circuits (ie they operate even if the main switch is off) Ideally this panel would be used in conjunction with the #7610 Automatic Battery Combiner.
