Since it is a main and not a subpanel, that is correct -- both white and
bare wires can be (and usually are) connected to each bar.
RBM wrote above saying the same thing:
"If it is the main service panel, the neutrals and grounds go on the same
buss. If it is a sub-panel, there will be separate neutral bars and
equipment ground bars."
And, Nate Nagel wrote that that is correct. Others probably did too, but
I'd have to go back and read all the messages again to check.
But, again, what you wrote ("There are BOTH white and bare wire's hooked to
EACH bar") is correct for a main panel.
Depends where in the world he is. In Canada, there are 2 busses - one
ground (for bare wire) and one neutral (for white wire) - bonded for
main panel and not bonded for sub. - and code requires the neutral and
the safety ground to be installed on their correct Buss.
There are a number of manufacturers, each makes a pile of panel styles, with
a multitude of neutral/ground buss arrangements. In the US , regardless of
the buss arrangements, if they are attached together, attached to the
service neutral, and the grounding electrode system, you can attach both
neutrals and grounds to them.
There are some panels made, which Bud made reference to, that have an
equipment grounding "only" buss. This buss is attached to the frame of the
panel only, and not to the service neutral conductor except via the steel of
the cabinet. It may be that in Canada, this type of arrangement is what's
required by code
If it does say that, it's a new addition since the installation of the
panel in my house (and/or whoever did it didn't do it to code - but I
would ASSume that one would have pulled a permit for a panel replacement...)
I agree that it seems like a good idea, I just haven't seen it done.
I believe there's something in there about not putting more than one
neutral wire under a single screw, though? You can have more than one
ground under a screw, just no more than the connection is rated for
(e.g. it might be 3x 14AWG, 2x12AWG etc.) but only one neutral. I
assume this is to remove the possibility of opening a neutral on an
energized circuit while trying to service a different circuit.
Yes, I am in the YooEss. Not an electrician, but pretty handy. I do
try to "do things right" but don't pretend to know everything about code.
replace "roosters" with "cox" to reply.
