This helps to reduce the potential difference that exists between conductive parts and the earth. The grounding "bus" (grounding bus, PE bus) in the box is directly connected to the power ground wire or grounding system; 2. Today, we're diving deep into the world of distribution box grounding, breaking down the standards, and shining a light on those sneaky mistakes that even experienced electricians sometimes make. If the height of the electrical equipment is less than 6. 5 feet, the minimum workspace height shall be equal to the. Metal raceways, cable trays, cable armor, cable sheath, enclosures, frames, fittings, and other metal noncurrent-carrying parts that are to serve as grounding conductors, with or without the use of supplementary equipment grounding conductors, shall be effectively bonded where necessary to ensure.
