Grounding Electrical Panel

The connection is often unreliable.

Grounding electrical panel.

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. When this happens you must bring an appropriately sized equipment grounding conductor over with the circuit to the subpanel you must not have a neutral to ground bond in the panel and the grounding electrodes are optional although highly recommended. Grounding and bonding happen simultaneously during the installation of an electrical system and branch circuits. Because the panel must be connected to the.

Alternatively you might consider connecting the ground terminal to a water pipe by means of an exposed ground wire. They work hand in hand in order to make it safe. The grounding pathway is generally formed by a system of bare copper wires that connect to every device and every metal electrical box in your home. If your electrical cables have metal sheathing that runs all the way to the panel the sheathing can serve as a ground path.

In standard sheathed nm cable this bare copper wire is included along with the insulated conducting wires inside the cable. By shunting excess line voltage back to the panel s neutral pole the ground current forces the circuit breaker to trip. The tripped breaker shuts off the circuit s current preventing a potentially dangerous situation. Distance from the electrical panel nec article 250 does not specify a minimum or maximum distance between the main electrical panel and the ground rod.

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. Two problems make the safety of these approaches questionable. Which scenario is recommended.
