The electrical ground is the rebar in the foundation.
Grounding electrical panel to water 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.
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.
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.
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.
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.
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.
A premise s electrical service shall be connected to a grounding electrode system consisting of a metal underground water pipe in direct contact with earth for 10 feet or more if available on the premises and a supplemental electrode a rod pipe or plate electrode.
