INSTALLATION INSTRUCTIONS
IMPORTANT: Installation of this power inlet box and related wiring must be done by a qualified
electrician in compliance with all applicable electrical codes.
INSTALLING A REMOTELY LOCATED POWER INLET BOX FOR CONNECTION DIRECTLY TO A
HARD-WIRE TRANSFER SWITCH OR PANEL
Mount the power inlet box on the outside of the building in a convenient location at least 24 inches above grade level,
using the mounting holes provided in the back of the cabinet. Using approved wiring methods, run the wiring through
one of the knockouts in the cabinet directly to the wiring compartment of the transfer switch or panel. If using conduit,
pull at least three color-coded wires (AWG #8 minimum) -- use white for neutral, and two other distinguishing colors
(typically black and red) for the 240V line. If not using conduit or if otherwise required, include a green wire as a
separate ground wire.
Connect the wires that you bring into the power inlet box as follows:
240-Volt line wires to the circuit breaker terminal screws.
White wire to white power inlet wire lead using a wire nut.
If required, green wire to green ground wire lead using a wire nut.
Wire connections are to be made at the transfer switch or panel according to manufacturer’s instructions.
MAIN CIRCUIT BREAKER
This unit is equipped with a 50-amp. main circuit breaker, which must be in the “ON” position when power is supplied
from the generator to the transfer switch or panel. If necessary, reset this circuit breaker by moving the handle to the
“OFF” position, then “ON”.
PREPARING A CORD FROM THE GENERATOR TO THE POWER INLET BOX
Using a 4-conductor 50 Amp. portable cord suitable for the purpose, attach a male plug matching the configuration of
the generator outlet to one end, and a Type CS6364 connector (which will mate with the power inlet in the power
inlet box) to the opposite end.
Following the wiring device manufacturer's instructions, wire the generator plug and the CS6364 connector as
follows:
Red and black wires to the brass terminals marked "X" and "Y".
White wire to the nickel-plated neutral terminal marked "W".
Green wire to the green ground terminal marked "G".
