Handhole Grounding
Handhole Grounding
(OP)
480V, 3W system. Equipment bonding conductor sized per the overcurrent device. Running 3-1/C#2 and 1-1/C#8 GND from source to building via ductbank with handholes. Do we have to bond the rebar in the handholes to the bonding conductor? How could you / is it necessary to ground a metallic cover?
