What can never be used as a main source of grounding for a home?

A gas meter cannot be used as a main source of grounding for a home. Grounding systems are essential for safety, providing a path for electrical current to follow in case of a fault. They help to prevent electrical shock, equipment damage, and fire hazards.

The grounding system typically includes components such as ground rods, water pipes, and the electrical panel, all of which are grounded to the earth to help disperse electrical energy safely. In contrast, a gas meter is not designed to absorb or dissipate electrical energy and is primarily intended for gas utilities. Therefore, it does not provide any adequate grounding because it lacks the necessary conductive path and continuity to the ground.

In addition, using a gas meter as a grounding source can introduce potential hazards, such as the risk of explosions or fires if electrical faults occur in conjunction with gas service. Proper grounding should utilize designated and compliant systems specifically designed for electrical safety, ensuring the protection of both the property and its occupants.
