1. A simple question about electricity...... (score: 1): Author: "Gerald Brazil" <gerrybraz@voyager.net>; Date: Tue, 24 Jul 2001 20:29:21 -0400; I would appreciate a simple explanation of typical wiring.... A basic 110v circuit consists of a hot wire (black), a common wire (white) and a ground wire (green) A 220 v circuit consists or two hot; /html/shop-talk/2001-07/msg00123.html (8,189 bytes)

(score: 1): Author: Randall Young <ryoung@NAVCOMTECH.COM>; Date: Tue, 24 Jul 2001 17:44:52 -0700; The 220v circuit is completed between the two hot wires. In effect, they are 180 degrees out of phase with respect to each other, so if you meter from either leg to neutral (or ground), you will see; /html/shop-talk/2001-07/msg00124.html (8,526 bytes)

Otherwise, you're asking for problems, like, a fire.

The common serves a different purpose than the ground (aka safety ground), and is also tied back to the line transformer output.

The third wire you ran is a 'safety ground', since it doesn't carry power needed for the compressor or (I assume) welder.
