Step-by-Step Guide to Wiring Your Grounded Extension Cord Ends

1. Remove the screw from the top of the plug using the screwdriver.
2. Next, pull on the prongs of the plug to release the plug from its shell.
3. Loosen the set screw on the barrel cord grip.
4. Look at the inside of the cord grip and ensure the plastic screw is not covering any part of the opening.
5. Insert one end of the wire into the cord gripʼs top opening. Cord gripʼs threaded end should face the end of the cord once inserted. You may need to wrap tape on the cord end for easy insertion.
6. Insert the same end of the cord into the plug shellʼs small opening.
7. On that same cord end, Measure 11/4 “ from the tip of the cloth covered wire, and wrap an inch of electric tape over the wire.
8. Over the midsection of the tape, strip the PVC housing to expose the 3 conductor wires. We recommend the use of our Color Cord 3000 striping tool or your own stripping tool if you already have one.
9. Make sure that there are no cuts on the conductor wires exposing the internal stranded copper wire.
10. Strip one end of each wire to expose about 1/4” of stranded copper wire.
11. Using your fingers, twist the stranded wires together and bend them.
12. Locate the positive (brass), negative (silver) and ground (green) terminals on the back of the plug
13. Loosen the 3 screws on the back of the plug to open the terminals.
14. Wrap the stranded copper wires on each matching terminal screw. The black wire (+) with the positive terminal, white wire (-) with the negative terminal and green wire with the ground terminal.
15. The stranded copper wire should be tucked in the terminal, covered by the screwʼs head.
16. Tighten the screws of each terminal to secure the wire in place. Pull the wires to make sure the wires wonʼt pull out of the terminals.
17. Pull the plug shell over the plug making sure that the screw hole on the cap aligns with the one on the plug.
18. Tighten the plug screw to secure the cap onto the plug. Bring the cord grip towards the plug and insert the threaded ends into the capʼs opening.
19. Twist the cord grip until its tightly secured.
20. Tighten the set screw on the cord grip.
