INSTALLING A REMOTELY LOCATED POWER INLET BOX FOR SUPPLYING POWER TO THE
POWER INLET OF A CORD-CONNECTED TRANSFER SWITCH OR PANEL
If your transfer switch or panel is provided with a power inlet for cord connection, it will be necessary to install a
junction box with an attached cord and cord connector of a configuration that mates with the power inlet.
The cord and connector assembly from the junction box to the transfer switch or panel power inlet should be four-
conductor cord suitable for a 20 Amp. load (AWG #12 minimum). The insulation on each of the wires is colored to
identify with the standardized coding in plugs and receptacles. Wire colors are usually white, green, black, and red.
One end of the cord will be connected to the wires in the junction box, and the opposite end will be connected to a
connector that mates with the power inlet of the transfer panel (Type L14-20 connector for all Reliance Genswitch™
and ProTran® 5000-watt transfer switches). Remove one junction box knockout and insert a cord grip and the cord.
Connect the wires in the junction box as follows:
Red and black cord wires to 240V line wires from the power inlet box.
White cord wire to the white neutral wire from the power inlet box.
Green cord wire to junction box ground screw.
Green wire from power inlet box, if required, to junction box ground screw.
Following the wiring device manufacturer's instructions, wire the cord 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".
A diagram of the this arrangement is shown below. It is not necessary to detach the connector from the transfer
switch when generator is not in use, and for convenience may be left in place at all times.
