Explain briefly about grounding of cable trays.

1 Answer

Answer :

Cable trays are grounded because to avoid any shocks to personnel incase of leakage. A grounding wire runs at the side of tray through a parallel groove clamp through out the length of the cable tray. If trays are one above another we can loop up the grounding wire to the tray below. This saves extra ground wire.
