What does grounding a light do?
Grounding is a safety feature for AC wiring that can absolutely save your life during a power surge or a storm, as it redirects all that excess energy into the ground where it is safely discharged, instead of turning you into a lighting fixture.
What does grounding a light fixture do?
Grounding is a safety feature used in electrical wiring. Grounding reduces the risk of serious electric shock by distributing displaced electrical current throughout the grounding system in your home and finally into the ground via the "grounding rod".
Why is a ground wire needed?
