We just bought a new house and want to upgrade the electrical system, some of which was done in the 60's when the house was built. The vast majority of the electrical outlets have only 2 wires, the ground terminal is missing.
Some of the outlets are in the basement, where the wiring is partially accessible however.
Is it legal (according to the electrical code) for me to change the outlet to a more modern 3 prong type and to obtain a ground from a nearby copper pipe or from one of the nearby plugs that already have a
3 prong outlet???? I notice the previous owner did this in several locations, but I need to know if it's legal to obtain a ground in this manner???We live in Maine, but belive the National Code is the one that has jurisdiction.
Thanks,
A
