Also, all outdoor outlets must have GFCI (ground-fault circuit-interrupter) protection.

it’s possible for you to meet this requirement simply by installing a new GFCI outlet.

Note:The new circuit cable and GFCI receptacle must have the same amperage rating as the existing circuit.

This prevents you from having to drill through a stud to fire off the new circuit cable.

The tester should indicate no voltage for everything in the electrical box.

Pop out the knockout with a hammer and screwdriver.

Materials for adding an outdoor outlet to an existing circuit

you might drill through the knockout hole in the box, if applicable.

Strip 3/4 inch of insulation from both ends of the black and white insulated wires, using wire strippers.

The third wire is the bare copper ground wire.

Determining the outlet location

You will use these three wires aspigtailsto connect the indoor receptacle to the circuit wires.

Strip 3/4 inch of insulation from the black and white insulated wires.

Do the same with the three white wires, then the three ground wires.

Turning off the power at the circuit breaker

Connect the white (neutral) pigtail to one of the silver (neutral) terminals on the outlet.

Connect the black (hot) pigtail to one of the brass (hot) terminals on the outlet.

Tuck the wires neatly into the electrical box and secure the outlet to the box with the original screws.

Testing to make sure the power is off

Reattach the outlet’s cover plate.

roll out the Outdoor Box

Remove one of the knockouts on the back of theoutdoor electrical box.

Feed the new circuit cable through the knockout hole, and secure the cable with a cable clamp.

Disconnecting the outlet

The Spruce / Kevin Norris

Mount the box to the wall with exterior screws.

Connect the bare copper ground wire to the green ground screw terminal on theGFCI outlet.

Tuck the wires neatly into the box and secure the outlet to the box using the provided screws.

Removing the box knockout

implement the outdoor box cover as directed by the manufacturer.

Join the pigtails and the circuit ground wire with a wire connector.

Also, test the TEST and RESET buttons on the GFCI outlet, as directed by the manufacturer.
