Generated explanation

The illustration shows an open main electrical panel beside a basement foundation wall and floor framing. A green grounding conductor runs from a terminal bar in the panel to a connection on the incoming water supply piping near the basement floor. The conductor is identified as part of the Grounding Electrode System (GES). Service conductors enter the panel at the upper right, and an annotation explains that the neutral service conductor returns to the street and is grounded at the utility pole or transformer box. Branch circuit breakers, terminal bars, and outgoing circuit wiring are also shown.
