How to Run a Ground Wire to an Electrical Panel Box | Hunker
Your service panel’s ground wire prevents a line fault from becoming a shocking experience. By shunting excess line voltage back to the panel’s neutral pole, the ground current forces the circuit breaker to trip. The tripped breaker shuts off the circuit’s current, preventing a potentially dangerous situation.
Which takes precedence over the inspector and the NEC?
That's the bottom line. ALWAYS consult the utility "green book" first. The poco rules take precedence over the inspector and the NEC.
Why is GEC important?
The primary reason for the GEC is for surges and lightning events, so why would we want to route this into the interior of a building or panel?
Is a meter base grounded?
The meter base (in line meter base) will be grounded whether or not a grounding electrode conductor is taken into the actual meter base or not. The grounded conductor of the system will perform this function due to the connection to the grounding electrode system installed at the premises served.

Does GEC matter in meter base?
It doesn't matter if the GEC lands in the Meter base or the Main Breaker enclosure, the grounded conductor in the service entry bonds the two together.
What percentage of current flows in a grounding electrode?
Due to the skin effect, especially in the larger wire sizes, only 3 percent of the current flows in the grounding electrode conductor, while 97 percent flows in the enclosing metal raceway. The relatively high resistance of the flex makes it a poor choice to enclose the grounding-electrode conductor.
Can neutral current travel through conduit?
The argument against allowing neutral current to travel on the conduit system is twofold: First, the impedance of the neutral conductor will be increased, and second, the conduit may be in contact with building steel, other piping, etc., creating other alternate paths.
Does metal flex have higher resistance than other raceways?
Metal flex has a much higher resist ance than the other raceways permitted in 250.64 (B) because the oil used in the manufacture of the flex makes in effect the resistance based on the cross section of the steel pulled out to its entire length, approximately three times the length of the run.
Can a PVC raceway be used for a transformer?
The correction, again, is to replace the steel conduit run between the transformer and the first disconnect (usually the main in a panelboard) with a rigid nonmetallic raceway (PVC). If the bonding jumper is installed at the transformer secondary terminals, the neutral bar in the enclosure for the first disconnect should be insulated. Otherwise, even with a PVC raceway connection there could be a parallel path for the neutral conductor through building steel to which both the transformer enclosure and the enclosure for the first disconnect are fastened.
Why do you have to ground a neutral in a meter socket?
A good example of that is our multi-gang meter sockets, where you have to ground, bond and connect the neutral in the meter socket because the neutral is isolated and you do not want multiple grounding connections (one in each of the panels) to be present.
Why is my meter socket not faulting?
In theory, the meter socket could become energized and not fault because the neutral block is not always attached to the meter socket; sometimes it is isolated. A good example of that is our multi-gang meter sockets, where you have to ground, bond and connect the neutral in the meter socket because the neutral is isolated ...
