Hi I considering buying a home in Loganville, GA. and had a home inspector look at the electrical system in the home that he said it was fine. I was looking over his shoulder during the inspection and am not sure he is correct about the panel being wired correctly. I have some questions about the neutral and ground bus bar bonding at the service panel.
Outside the home there is a 200A single phase Meter Base that has a service disconnect. From there is 4 wire feeder cable going to the service panel inside the home (separate ground and neutral and the two 120V legs). Both the ground and the neutral wires of the feeder cable are bonded together in the meter base box on the outside of the house. Inside the service panel in the house the feeder cable connections are as follows: ground wire connects to the ground buss bar and the neutral wire connects to the neutral buss bar. Also there is a #4 AWG bare copper ground wire going from the ground buss bar in the service panel to two ground rods outside the home. The ground buss bar and the neutral buss bars are bonded together in the service panel inside the home. I also noticed that the neutrals and ground wires from the individual circuits were mixed on the ground and neutral bus bars.
So my question is, since the meter base outside has the disconnect shouldn't the ground and neutral buss bars in the service panel be separated (remove the bonding bar that runs between them), the bare #4 AWG copper wire for the ground rods be moved to the meter base where the neutral and ground feeder cables are bonded together, and the mixed neutral and ground wires in the service panel be installed on the correct buss bars? I'll have the current home owner get an electrician to make the changes if this needs corrected before I close on the home.
