Re: [PSUBS-MAILIST] Electrical thru-hulls



Hi Brent. That sounds like a viable plan. Making your sub a "wet sub" but still 1 ATM. requires some very innovative solutions. Would it be possible to make some of the systems as stand-alone "components"
that are sealed inside water tight boxes, with just the cables or flexible HP hoses connecting them. I'm assuming the sub won't be all that deep when you flood it for training exercises, so maybe just some off-the-shelf hoses and connectors between boxes would be fine for keeping some of the more sensitive parts from getting wet.
I'll be making stainless boxes for all my batteries, and although they won't be totally water "proof", the neoprene gaskets and suitcase type latches should keep any gas build-up inside and any water or vapor out.
The small control panel will be the same type of set-up.....a small stainless box with the 4 speed control dials and the three rocker switches for dive plane and rudder control. This will be loose on the end of the cable harness so it can be moved about inside the sub or reached through the hatch when topside.  Frank D.
