I need to tap some electrical in an underground garage where my car
is. There are no wall outlet whatsoever and sometimes I need to plug
in some hand tools. Anyway, I found this box hanging off the low
ceiling, I opened and saw thew 5 wires, 4 wiht shield and 1 just
barecopper(ground). Can someone in the know please tell me which of
these wires I can splice into to get teh equivalent household voltage
of 120V, I plan to add a wall socket to it. I promise I will be
careful, where gloves etc. Thx
