How to Install the PF and PFQ Series Plugs and Receptacles
This guide provides step-by-step instructions for the safe installation and wiring of PF and PFQ series plugs and receptacles in high amperage applications.
Estimated time: 45m
Tools needed:
7/8" wrench, 5/16" Allen wrench, 10 mm wrench, Screwdriver, Wire strippers, Multimeter
Supplies needed:
Mounting screws, Terminal connectors, Heat shrink tubing
- Verify power is off
Before starting the installation, ensure that all sources of power to the circuit are disconnected to eliminate the risk of electrical shock.
- Mount the receptacle
Secure the receptacle to the junction box cover using the provided bolts. Ensure that the locking cam remains easily accessible.
- Connect conductors
Strip the conductors 0.5 inches (12 mm) and connect them to the respective terminals as per the wiring instructions. Use the appropriate lugs and ensure that the neutral and ground wires are positioned above the phase wires.
- Apply heat shrink tubing
After connecting the conductors, apply heat shrink tubing over the lugs and terminals to prevent short circuits.
- Secure the handle cover
Attach the handle cover using the 8 mm Allen tool and the six screws provided. Ensure that the cover is securely fastened.
- Tighten cable gland
Compress the grease-coated cable gland by tightening the hub to achieve the recommended torque of 150 to 280 lb-ft (200-400 N-m) for IP67 rating.
- Verify connections
Use a multimeter to verify the electrical continuity of the ground circuit and ensure all connections are secure.
- Perform final checks
Check the mounting screws for tightness and ensure that the weight of the cable is supported by the strain relief mechanism, not by the terminal connections.
