What’s an SDPM? We’re glad you asked!

Grounding – A grounding wire is attached to outlets and other electrical devices and then securely connected to the ground at the breaker box.

This direct physical connection to the earth is critical, as the earth acts as a reservoir of charge and can neutralize an electric current. Along with circuit breakers, grounding wires are standard safety devices used with today’s electrical circuits.

Grounding of customer equipment must be in accordance with the latest issue of the NEC (Article 250 Grounding). Code enforcement agencies may require ground connection to be visible when an inspection is made. However, for safety reasons, the top of the ground rod should be flush or below ground level in permanent application.

Meter – A device that measures and records the summation of electrical energy over a period of time

Meter base ring – A metallic ring that secures the meter to the meter socket and can be sealed by PGE

Meter socket – The mounting device consisting of jaws, connectors, and enclosure for socket-type meters. The meter socket is also referred to as a meter base.
