[PSUBS-MAILIST] penetrator

[Alec Smyth via Personal_Submersibles]

I just checked ABS and the separate penetrator rule only applies to the
penetrations for batteries outside the pressure hull. With a motor supplied
from inside you would have a way to cut the power. That said, obviously you
will still want to insulate everything to prevent accidental shorts,
because if you had to cut power to the penetrator you would be forgoing
your propulsion.

Best,

Alec
