To wire a NEMA 6-15 plug, follow these steps:
1. Turn off the power supply before starting.
2. Strip the outer insulation of the wire, exposing the individual wires.
3. Connect the black wire to the brass terminal on the plug.
4. Connect the white wire to the silver terminal on the plug.
5. Connect the green wire to the green terminal (ground) on the plug.
6. Tighten the screws on each terminal to secure the wires.
7. Double-check all connections to ensure they are secure.
8. Test the plug to make sure it is functioning properly.
Remember to always exercise caution when working with electricity to avoid any accidents or injuries.
A NEMA 6-15 plug consists of two straight-blade prongs aligned horizontally and one prong in the shape of a horseshoe. The prong configuration of a 6-15 plug is specifically designed to fit into a NEMA 6-15 receptacle. The horseshoe-shaped prong is inserted into the ground terminal of the receptacle, while the horizontal prongs of the 6-15 plug are inserted into the hot slots of the receptacle. A NEMA 6-15 plug is used for a 250-volt, 2-pole circuit with a ground and is commonly used to supply power to window-mounted air conditioners and commercial office equipment.
About the Electrical Cable
Typically, when wiring a 240-volt circuit, a 10-gauge or heavier 3-conductor wire is used. However, a circuit controlled by a NEMA 6-15 plug requires a different approach. It is recommended to use a 14-gauge wire, and since the plug does not have a neutral terminal, a 3-conductor cable is not necessary. It is advisable to use a 2-conductor 12-gauge wire instead. The thicker wire provides added safety against overheating and potential fires. To differentiate the hot wire from the neutral wire, wrap black or red tape around the white wire inside the plug and at the circuit breaker.
Connecting the NEMA 6-15 Plug
Using wire strippers, remove the last 3/8 inch of insulation from the end of each wire that will be connected to the NEMA 6-15 plug. Some wire sets consist of three insulated wires (usually black, white, and green) while others have two insulated wires (usually white and black) with an additional uninsulated wire. Remember to identify the white wire as the hot wire.
With a pair of pliers, grip the middle of the stripped portion of each wire and shape the end into a hook. Using a Phillips screwdriver, loosen the three wire terminal screws of the NEMA 6-15 plug. The ground terminal of the plug is identified by a green screw and the letter “G” stamped into the plug’s body. The two unlabeled terminals are brass and are used to connect to the live wires.
Slip the hook of the ground wire over the ground terminal screw of the NEMA 6-15 plug and tighten the screw. The ground wire, which is usually green or uninsulated, provides protection against accidental electrocution. Connect one of the hot wires to one of the hot terminal screws of the NEMA 6-15 plug (either one will suffice) and tighten the screw. Connect the remaining wire to the other terminal in the same manner.
Finalize the Installation Safely
Once the wire connections have been made, double-check to ensure that no exposed wires are touching inside the plug. Slide the plug casing together and tighten the screws to secure it. The plug should have a cable clamp attached to it; tighten the clamp and give the plug a firm tug to ensure it is securely in place before plugging it into the 6-15 receptacle.
