How to Install MELTRIC PN Series Electrical Plug and Receptacle

Step-by-step guide for safely installing and wiring MELTRIC PN Series electrical plugs and receptacles in industrial and commercial applications.

Estimated time: 1h

Tools needed:

Screwdriver (3mm/1/8" precision tip), Wire strippers, Allen wrench (5/16"), Multimeter

Supplies needed:

Mounting screws, Watertight seals/gaskets, Lock washer, Mounting nuts

  1. Verify Power Disconnection

    Disconnect ALL power sources to the circuit to eliminate electrical shock risk. Use a multimeter to confirm no voltage is present.

  2. Prepare Cable

    Insert cable through handle and strip cable jacket. Ensure jacket extends at least 1/2" into handle for secure grip. Strip individual conductors according to Table 3 wire strip lengths.

  3. Wire Terminal Connections

    Insert conductors fully into respective terminals. Twist conductor strands before insertion. Tighten terminal screws to 8 in-lbs using a 3mm/1/8" precision screwdriver.

  4. Mount Receptacle

    For custom mounting, drill holes according to Table 6 dimensions. Use watertight seals under mounting bolt heads. Secure with lock washers and nuts inside box/panel.

  5. Ground Connection

    Connect green ground conductor to designated ground terminal using green screw. Verify electrical continuity of ground circuit.

  6. Final Verification

    Check all connections are tight. Verify IP rating is maintained. Ensure cable weight is supported by strain relief, not terminal connections.
