Connect Ground to 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 mm2), copper, stranded wire.

■Bond all approved grounds at the single-point ground to form a single grounding electrode system.

AC Load Center is 50 Feet (15.2 m) or Less from
