INSTALLATION OPERATION &
MAINTENANCE DATA SHEET
3. Receptacle Installation
3.1. Enclosure mounting
Securely mount the receptacle in a vertical posi-
tion as illustrated, using three 5/16" (8 mm)
screws and suitable washers. Mounting dimen-
sions are marked on the back of the receptacle
housing.
3.2. Conduit/Cable Installation
For conduit installation, connect 1 1/2" NPT con-
duit to the hub and avoid misalignment. For
cable installation, connect a listed cable fitting to
the hub. Conduit/cable fitting should not be tight-
ened more than 60 ft-lbs (81 N-m) of torque.
3.3. Wiring
Open the terminal cover and connect 75°C cop-
per supply wires. The supply side of the terminal
block accepts up to two wires which are
between 6 through 2 AWG per terminal. Allow
proper length for bending and cut the conductors
to length. Strip the conductor insulation 1" (25
mm) from the end. Insert the conductors into the
appropriate terminals which are marked to corre-
spond with the markings on the plug. Torque all
terminal screws to 54 in-lbs (6 N-m); including all
unused terminals.
3.4. Auxiliary Contact
When using the 20 ampere rated early break
and late make auxiliary contact for an electrical
interlock or other control signal, connect 12
AWG copper wire to terminals 13 and 14. Torque
the terminal screws to 18 in-lbs (2 N-m).
3.5. Function Label
Remove the plastic function-label (taped inside
the cover), mark as required, remove backing
strip and apply to the recessed area above
switch. Close the cover and tighten the cover
screws.
