Wire location

[triplethreat]

Does it matter where the wires go in a panel? All my wires including the service wire all come in from the top. I want to add another wire for a sub panel but their is no room at the top. Is it okay to come in from the side or the bottom? I would think it wouldn't matter since their are knockouts on the sides and bottom. I did notice that my new 100 amp breaker is rated for 2/0 wire on the SQ D side and my cuttler hammer 100 amp BR breaker is only rated for 1/0. I'm running 1/0 SER AL wire from the main panel to the sub panel. Thanks in advance.

Wherever you want.

If there is not a KO (knock out) where you want one, it is permissable to hole saw an opening in any place convienient.

Only if it has a main breaker that is partitioned off with a barrier from the rest of the panel.That area is reserved for the service entrance conductors only,the remaining three sides can be entered as you and of course,good workmanship permit.
