INSTALLATION
A.
As specified in Section 16050.
B.
Provide a separate, green insulated, grounding conductor in each raceway
independent of raceway material:
1. Multi-conductor power and control cables shall include an integral green
insulated grounding conductor.
2. Provide a separate grounding conductor in each individual raceway for parallel
feeders.
C.
Provide a separate grounding conductor for each motor and connect at motor
terminal box. Do not use bolts securing motor box to frame or cover for grounding
connectors:
1. When grounding motors driven by variable frequency drives (VFD) comply with
the requirements of the VFD manufacturer.
D.
Provide a grounding type bushing with lug for connection of grounding conductor for
conduits that originate from each motor control center section, switchboard, or
panelboard:
1. Individually bond these raceways to the ground bus in the equipment.
E.
Provide grounding type bushings with lugs for connection of grounding conductor at
both ends of metallic conduit runs. Bond ground bushings to the grounding system.
F.
Provide a green insulated wire-grounding jumper from the ground screw to a box
grounding screw and, for grounding type devices, to equipment grounding
conductor.
