No, the ground wire (green) can be strapped to any metal pipe going to ground. In the absence of a suitable pipe a metal stake at least 6 feet long can be driven into soil and the wire strapped to that.

Most new homes today do not use copper pipe for Plumbing because of the high cost of copper. PVC is used as a replacement product. The electrical code requires that grounding rods or grounding plates must be used as the main grounding medium in electrical service distributions.

The ground wire sized from the panelboard ground bus to the grounding rods or plate is calculated by the amperage of the service's first over current device (main breaker) where the service wires enter the home.


If grounding rods are used as a service ground, there have to be two 10 ft rods spaced 10 foot apart. If ground plates are used, only one is needed buried to a minimum depth of 18 inches below grade.


If there is a metallic water line entering the home, or a metallic gas line, they have to be bonded to the distribution service ground. The key word here is bonded and this means that they are not to be used as the main ground for the electrical service distribution.

No, although the electrical system is sometimes grounded to the Copper water lines. This does not pose any problems.
