<div dir="ltr">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. <div><br></div><div>Best,</div><div><br></div><div>Alec</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sat, Dec 17, 2016 at 11:37 AM, Brian Cox via Personal_Submersibles <span dir="ltr"><<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="font-family:Arial,sans-serif;font-size:10pt"><div>Alan, Alec, My batteries are inside, this would be power going to the motor.
