Hi Larry,<br><br>I have worked in a marina for
the last 28 years. I have seen a lot of burnt wiring
systems that did not blow the main fuse. It allows you to
disconnect all power when you leave the boat or are working
on it with out having to unhook the battery cables.
The only thing I would leave "Hot" would be a battery
monitor or bilge pump. These would have their own fuses
located before the Discocnnect Switch. There might be
other times needed, but I can not think of any at this
time.<br><br>Good luck with your project.<br><br>Jim
