Splitting service to a new power meter. I just cut the wires coming out of the meter box and now the grounding cable is 2' short of the grounding rod. Must the ground wire be continuous from the panel box, through the meter to the grounding rod?
In most circumstances it isn't necessary (or advisable) to go "through the meter", but your exact installation would need to be addressed. The wire should be continuous.
