Cabling
Where the cable enters the wiring base, use the supplied cord grips
with rubber grommets. Each cord grip comes with 2 different size
grommets.
Cord grips with small diameter grommet accommodate wire
diameters 0.191 to 0.354 inches (4.9 to 9.0 mm).
Cord grips with large diameter grommet accommodates wire
diameters 0.236 to 0.472 inches (6.0 to 12.0 mm).
You can obtain additional cord grips from most electrical supply
outlets. Make sure you use Teflon tape or other type of thread
sealant to maintain a NEMA Type 4 rating.
