First, you will need to strip the insulation off the end of the extension cord to expose the three wires inside: the hot wire (usually black), the neutral wire (usually white), and the grounding wire (usually green or bare copper).
Next, you will need to connect the hot wire to the brass terminal screw, the neutral wire to the silver terminal screw, and the grounding wire to the green terminal screw. Make sure to tighten the screws securely to ensure a good connection.
Once you have connected all three wires to their respective terminal screws, you can then reassemble the plug by securing the casing and tightening any screws that hold it in place. It’s important to double check your connections before plugging in any devices to ensure everything is wired correctly.
In conclusion, understanding how to wire a 3 prong extension cord is essential for ensuring safety and preventing electrical hazards. By following the correct wiring diagram and making sure all connections are secure, you can safely use your extension cord for all your electrical needs.
