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.
Grounding electrical panel to water 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.
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.
All of the following 7 electrodes that are present at a building shall be bonded together to form the entire grounding system.
Single grounding electrode to perform its function over the life of an electrical installation.
The electrical ground is the rebar in the foundation.
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.
Metal underground water pipe including any well casing bonded to the pipe.
Have your electrician use a clamp on amperage meter to measure the current on the water pipe grounding electrode conductor gec and onto the copper pipe itself if the clamp will go around the.
The copper plumbing is properly bonded to the main electrical ground at the electrical panel.
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.
