Wiring a 20a 125/250v Locking Plug
Before you start wiring a 20a 125/250v locking plug, it’s important to have a clear idea of the wiring diagram that you’ll be following. Here’s a step-by-step guide on how to wire this type of plug:
Step 1: Gather Your Tools and Materials
Before you start wiring your 20a 125/250v locking plug, you’ll need to gather the following tools and materials:
- A Phillips screwdriver
- A wire stripper
- A wire cutter
- A locking plug
- A length of cable with three wires (black, white, and green)
Step 2: Prepare the Cable
Using your wire stripper, remove about 1 inch of the outer insulation from the cable. Then, strip about 1/2 inch of insulation from each of the three individual wires.
Step 3: Open the Locking Plug
Using your Phillips screwdriver, remove the screws that secure the locking plug cover. This will allow you to access the wiring terminals inside.
Step 4: Connect the Wires
With the locking plug open, you should see three wiring terminals labeled “L,” “N,” and “G.” Connect the black wire to the “L” terminal, the white wire to the “N” terminal, and the green wire to the “G” terminal.
When connecting the wires, be sure to wrap the exposed wire around the terminal screw in a clockwise direction. This will ensure a tight connection and prevent the wire from slipping out.
Step 5: Secure the Wiring
After you’ve connected the wires, use your Phillips screwdriver to tighten the terminal screws. This will secure the wires and prevent them from coming loose.
Step 6: Close the Locking Plug
With the wiring completed, you can now close the locking plug cover and secure it with the screws you removed in Step 3.
