Page 67 - see Talking Back, August 1997, page 10. Page 67 - A subpanel requires two separate bus bars, one for the ground wires and one for the neutral wires. The ground bus bar amounts directly to the panel box, and the neutral bus bar should rest on an insulating block to keep the neutral wires from contacting the panel box. Also, in a subpanel, the ground wire must come from the main service entrance panel to provide a "least resistance" ground path for any fault current. Remember, don't take chances with electricity. Always consult local codes and get the advice of a certified electrician before beginning any do-it-yourself electrical work.
