New home,2 bedroom, Peoria, IL, construction with 200 Amp service. I have a basic 30 space Sqaure D main breaker electric panel that I just purchased from Lowes.
I am ready to wire up all my breakers.
My questions is... which is the neutral bus bar and which is the grounding? They are both bonded together on the panel so does it even matter which is use to attach my white and ground wire to?
Plus, there are two isolated grounding bars screwed on opposite sides of the panel that are not bonded to the neutral bus bar...??? For what?
Does it matter which bars I use to connect my white wires and grounding wires?
I'd appreciate any help. Thanks.
