Grounding an AC-Powered System
(J58890CE)
Grounding is relatively simple for an AC-powered system. Basically, the cabinets connect to the single-
point ground terminal block located at either the AC load center or to a separate single-point ground
block wired to the AC load center (or optional AC protector cabinet).
•
The approved ground wire must be a green (or green with yellow stripe), 6 AWG (#40) (16 mm
copper, stranded wire.
•
Bond all approved grounds at the single-point ground to form a single grounding electrode
system.
