View Full Version : Conduit size vs. number of wires

09-06-2007, 04:48 AM
I have 2 12/2 MN ROMEX® running to a well pressure tank switch from the panel. above the pressure tank the ROMEX® is stripped and I have the 4 current carrying conductor and 2 grounds running in 1/2" conduit down the wall to a metal box containing a shut-off switch ( double pole 230v). My question is: is this to many wires or to large of wires for 1/2" conduit?
I looked in code book, but was unable to find the exact info I'm looking for, probably because I don't know the insulation type.
