[PSUBS-MAILIST] Electrical thru-hull

[Hugh Fulton via Personal_Submersibles]

I seem to remember that Rule of thumb is 2000 amps / square inch for copper so 50 amps would be 3/16” diameter.

¼” diameter would be OK for 100 amps. Hugh

Hank, Jon,

                       What diameter rod do you need for 50A ?

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, 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.
