Reliance PB30 Installation Process
Know how to install a remotely located Reliance Controls power inlet box for supplying power to the power inlet of a transfer switch.
Installing Reliance Power Inlet Box
- You need to mount the Reliance power inlet box on the outside of the building in a convenient location. By using the three-holed given at the back of the cabinet, you need to mount the power inlet box.
- Using copper wire and approved wiring methods, run the wiring through one of the knockouts in the cabinet to a junction box which is located near the transfer switch or panel.
- You have to pull at least three color-coded wires if there is a conduit. Use white for neutral and two other distinguishing colors, i.e., black and red for the 240 volts line. If not using conduit or if otherwise required, you need to include a green wire as a separate ground wire.
- Strip the wire insulation 5/8" and connect the wires in the power inlet box as follows:
- Make sure that no wire insulation is present in any terminal.
- The inlet terminal screws are secured to 20-inch pounds of torque.
- 240V line wires to the brass terminals markets "X and Y".
- White wire to the nickel-plated neutral terminal marked as "W".
- Green power inlet wire to the green ground screw terminal inside the cabinet.
- Green wire to the green ground screw terminal on the cabinet inside.

Installing a Junction Box and Cord Connector
If your Reliance 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 assembly from the junction box to the transfer switch power inlet is to be made of a four-conductor cord suitable for a 30 Amp load.
- The insulation on each of the wires is colored to identify with the standardized coding in plugins and receptacles. The wire colors are usually green, white, and red.
- You need to connect one end of the cord to the wires in the junction box and another end will be connected to a NEMA-type L14-30C connector which will mate with the power inlet on the transfer switch face.
- Now, remove one junction box knockout and insert a cord grip and the cord.
- You have to connect the wires in the junction box as follows:
- Red and black cord wires to 240-volt 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 to junction box ground screw if required.
- Wire the L14-30C 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".
It is not necessary to detach the connector from the transfer switch when a generator is not in use. You can leave it in place at all times for convenience.
