Grounding Electrical Panel To Water Pipe

The electrical ground is the rebar in the foundation.

Grounding electrical panel to water pipe.

As construction methods change a good understanding of grounding and bonding will ensure a safe installation and provide help in dealing with these gray areas. Section 250 104 b would permit the equipment grounding conductor for the electrical circuit that may energize the metal water pipe stub to serve as the bonding means. The copper plumbing is properly bonded to the main electrical ground at the electrical panel. Primary connection to the water pipe must be on the street side of the water meter primary connection to the water pipe shall be within 5 ft of the point of entrance to the building the nec requires that water pipes be bonded to ground even if these metal pipes are not used as part of the grounding system.

The wires that bond your metal piping are preventative and they only become important in the unlikely event that an electrical conductor energizes the pipe. The grounding wire that runs from your electrical panel to grounding electrode helps even out voltage increases that often occur because of lightning and other causes. Bonding is a non corrosive grounding wire that runs from a metal plumbing pipe back to the metal box of the home s main electrical panel to the wire that leads to a grounding rod outside the. Metal underground water pipe including any well casing bonded to the pipe.

Electrically conductive materials such as metal water piping metal gas piping and structural steel members that are likely to become energized shall be bonded as specified in this article to the supply system grounded conductor or in the case of an ungrounded electrical system to the electrical system grounded equipment in a manner that. All of the following 7 electrodes that are present at a building shall be bonded together to form the entire grounding system.
