Installation Steps:
- Disconnect Power: Locate the circuit breaker or fuse controlling the circuit where the receptacle will be installed and turn it OFF. Verify power is off using a voltage tester.
- Prepare Mounting Surface: Ensure the surface is clean, dry, and structurally sound. The receptacle is designed for surface mounting.
- Mount the Receptacle Base: Position the receptacle base on the desired surface. Use appropriate mounting screws to secure it firmly. The back of the receptacle features pre-drilled holes for this purpose.
- Wire Connections: This receptacle is a 2-pole/3-wire grounding type (NEMA 6-50). It typically requires two hot wires (L1, L2) and one ground wire.
- Strip approximately 1/2 inch of insulation from each wire.
- Connect the L1 (Hot) wire to one of the brass-colored terminals.
- Connect the L2 (Hot) wire to the other brass-colored terminal.
- Connect the Ground wire (typically green or bare copper) to the green hexagonal grounding screw.
- Secure Wiring: Ensure all wire connections are tight and secure. No bare wire should be exposed outside the terminals.
- Reassemble: Carefully place the cover over the wired base and secure it with the provided screws.
- Restore Power: Once installation is complete and verified, turn the power back ON at the circuit breaker or fuse box.
