How should grounding conductors be installed at an outlet box?

Grounding conductors should be installed at an outlet box in a manner that ensures safety and compliance with electrical standards. The correct approach involves first connecting the grounding conductor using an approved method. This may include using wire nuts, terminal blocks, or other connectors specifically designed for this purpose. After the grounding conductor is securely connected via an approved method, it can then be attached to the terminal that is designated for grounding in the outlet box.

This method protects against electrical faults and hazards by ensuring that the grounding system is effective. Properly done, this creates a low-resistance path back to the ground, which helps to trip circuit breakers or blow fuses in case of an electrical fault, preventing potential shocks or fires. In addition, adherence to this method ensures compliance with electrical codes that promote safety standards in electrical installations.
