Ok, I have installed my subpanel and wired up my sub panel receptacles. Now Im faced with my fear, the main LIIIIVE Panel. My question is: What exactly on my main service panel is LIVE??? I have reached the point where all I have to do is connect my breaker to the main panel but Im nervous because I dont wanna touch ANYTHING in the box until I know for sure Im not gonna get zapped. I want to screw in the neutral and the ground but that makes me nervous.
