ECN Forum Forums Technical Discussion Electrical Theory and Applications Gnd and Neut Wires Same Termination in Panel

I hope this isn't too dumb for the forum, but here goes:

I worked with an electrician who was big on directing process and not too big on explaining theory. Most directions were explained by "Because I said so."

I've noticed on forums here repeatedly the concept that you do not terminate ground wires and neutral wires in a panel on the same terminal strip. The old boss is retired and moved away, so maybe one of you pros can explain to me what the deal is here.

I should mention that we worked exclusively on residential.
