Technically it is more or less redundant - the two wires have no difference in potential - as say, the hot black and neutral would - but the 2 wires now serve completely different purposes once they leave the main panel.To add your country's flag to your flair, you must select a title from the drop down menu. Without this ground path the user might encounter a shock touching the device if it has an internal fault or in the case of electronics - internal circuitry damage may occur. In the event of a fault or short electricity has a quick way back to main ground. So this is the main purpose (and why it's required) for this isolated ground (isolated only in reference to the neutral) to provide that extra safety path back to the panel. The neutral, having an internal connection inside that device can NOT do this. Once you leave the main panel on any grounded system this extra added ground wire now serves a totally new purpose and because it is now isolated from the neutral from that point on - it adds the extra degree of protection that the neutral cannot - it is picking up any "bleed" to metal on all your appliances (the frame of your light fixtures or dryer or stove, etc) and taking that back to the panel and hopefully tripping the circuit breaker monitoring that circuit in the process. As you likely know, the neutral is the primary return path for any single phase circuit while the ground is a safety return path in the event of a fault - to help eliminate the potential for shock from any metal casing in the event of an internal short.Īt the main panel the service neutral and the outside ground rod (and any internal water pipe or supplemental ground for that matter) are all technically one and the same wire and point - but that is where it ends.
