The original two-pin electrical plug and socket were invented by Harvey Hubbell and patented in 1904. Called an AC plug or male electrical connector, it is a common electrical device that allows you to connect an appliance to an electrical outlet or power supply. AC plugs are made of durable plastic or rubber, but are subject to wear and tear. A damaged AC plug must be replaced immediately in order to avoid possible electric shock.
Things You'll Need
- AC plug
- Wire stripper
Open the new plug using a screwdriver. Some plugs snap on while others screw together.
Get the flat cord and split apart the two wires by about two inches, then strip away about 3/4 inch of the insulation on the wires with the wire strippers.
Connect the wires to the AC plug using a screwdriver. The black wire gets connected to the copper, or the darker colored screw. The white wire gets connected to the silver, or the lighter colored screw, and the ground gets connected to the green screw on the plug.
Replace the AC plug cover. Depending on the type of plug, screw back or snap the cover onto the AC plug.
Tips & Warnings
- Before replacing the plug cover, make sure that none of the wires are in contact with each other in order to avoid a possible short circuit.
