Question

Which one of the following is not a function of the grounding electrode? Grounding electrodes maintain all the noncurrent-carrying metal parts that are connected to the grounding system at ground potential. Grounding electrodes provide many paths into the earth to disperse electrons when very high current flows are caused by lightning or line surges. Grounding electrodes carry the current that operates the overcurrent protection devices in a system. Grounding electrodes drain leakage or static to ground.

Explanation / Answer

FUNCTIONS OF GROUNDING ELECTRODES:

1)The grounding electrode helps ensures that the ground wire and the ground around the structure (picture a concrete slab for example) are at the same voltage (or at about the same voltage).

2)A grounding electrode is to provide a low impedance path for lightning to get into the earth

Grounding electrodes doesnot carry any current therefoe option C is not a function of grounding electrode
