Warning: Before wiring any electrical devices, make sure the power is turned off at the circuit panel and test with a voltage tester.
When stripping wires, use the gauge shown on the back of the device to measure the correct length. Enough wire needs to be stripped so there is no insulation under the screw head.
Back wiring a device is when the wires (Black, white, green, etc.) are slid under the terminal clamp to the appropriate screw.
Side wiring a device is when the wires are attached using the side terminal screws. To do this, use a pair of pliers to bend the wire, creating a “fish hook", and place the hook around the appropriate screw. Tighten the screw so it holds the wire firmly in place.
