[PSUBS-MAILIST] Electrical thru-hull

[hank pronk via Personal_Submersibles]

Brian,I use a 1\4 in rod for 50a at 12v probably over kill especially since my runs are quite short.  I don't want to worry about heat in the penetrator.  The answer really is relative to wire length.Hank
Brian, was it you asking about a pen for coax- I used to use a 8mm cam corder in my log salvage ROV with a 350 foot coax in the ambilical.   I simply put an adaptor on the coax to bring it to two wires, like what you had on old tv's  then through the hull with two epoxy filled rods then back to the adaptor and into coax.  Never ever failed us and we had a perfect! image all the time.

 Hank, Jon,                       What diameter rod do you need for 50A ? Brian

Jon,That should work perfectly well, I would drill and tap the delron so the rods thread into it, if not threaded all the way at least partially.  You could solder the wires to the end of the rods or crimp.  Then encapsulate the connections, I assume that is what your thinking with that void at the top.  The beauty of your material choice is you can get more rods into one penetrator.  Hank

 Hank, I need penetrators for 36vdc power to motors (50amp), 12vdc power to lights (20amp), and other small electronic sensors.   Any thoughts about delron or nylon as a body for machining.  Attached is a design for threaded rod through delron that I came up.  The nuts on the threaded rod probably not necessary if locktite or epoxy is used on the threads before driving it into the thru-hull body.

|  Jon,
 What do you have to work with in terms of hole in hull. What amp are you trying to run through.
