[PSUBS-MAILIST] SubConn BH4F and IL4M Connectors

[Rick Patton via Personal_Submersibles]

Sean,
I have been very careful not to use the hull as a ground for obvious
reasons but was just wondering if there was any drawbacks to having the
breakers for the battery's attached to the lugs as soon as they inter the
hull? I would prefure them to be inside because they would be easier to
replace or reset plus I have a lot more room for them.
Why do both pos and neg need to be protected with fuses?
Rick
