Remove the cover from the
Outdoor Power Inlet Box
by unscrewing
the two screws on the front of the box with a #2 Phillips
screwdriver. Temporarily slide out the wiring tray. Mount the back
plate of the power inlet box on the outside of the building in a
convenient location, using the three holes provided. Remove one
of the POP-FAST reusable knockouts from the box by pushing out
from the inside of the inlet box. Using
copper building wire only
and approved wiring methods, run the appropriate wires from the
transfer switch wiring compartment through the removed knockout
in the power inlet box
.
3/4-inch fittings can be installed directly into
the knockout hole in the Power Inlet Box. To use 1/2-inch fittings,
insert the plastic knockout washer (provided in the power inlet box)
into the open hole, and then install the fitting.
Strip the wire insulation 5/8" and connect the wires to the wire ports
on the back of the power inlet in the power inlet box tray as follows
making sure there is no wire insulation in any terminal and the inlet
terminal screws are tightened to 20 inch-pounds torque:
Hot red wire to the terminal marked “X”
Hot black wire to the terminal marked "Y".
Neutral wire to the nickel-plated neutral terminal marked "W".
Ground inlet wire to green screw terminal marked “G.”
* On 125VAC only inlets, the terminals may be identified by the
screws; the brass screw is hot, silver screw is neutral, and green
screw is ground.
Slide the power inlet tray back into the
power inlet box and tuck the
wires in neatly. Replace the inlet box cover using the two screws.
These inlet boxes are rated for use
with wires having insulation rated at
60° C or at 75° C.
