Please explain to me what the green screw does for the main service panel ? Please explain to me what the bonding strap does? When is the bonding screw required and when is the bonding strap required ?
Are both bonding strap and bonding screw required in a GE main service panel ? As you can see the service wiring is two hot, a neutral and ground rod. Just wanted to make sure I understand.
Thank You In Advance
