Sometimes battery switches are not located in a very accessible spot. I prefer to have the battery switch easily accessible but not in the way where a foot could accidentally hit it. Take a look at this installation, where the battery switch was located behind the galley sink drain in a very difficult location to access. Also there were some circuit breakers and a reset button. Look very closely at the photo. Who would install something like this?
My solution was to relocate the main and engine battery switches to a recessed panel near the companionway entry. The companionway ladder blocks this so an errant foot cannot trip the switches, yet it can be easily seen or reached by hand.
Notice the new recessed switch panel also holds resettable circuit breakers for the anchor windlass and AC inverter as well as a battery system monitor.
This new design brings all the high current items to one central area, easy to manage and very short cable runs. Simple and done. Nice!
