Adding An Outlet To An Existing Circuit Diagram

Once power is verified turn off the electrical power to the wiring circuit.

Adding an outlet to an existing circuit diagram.

One cable is the incoming power source entering the box from one side while a second cable exits the box to continue onward to downstream locations on the circuit. The neutral wire from the circuit is shared by both sets. The source is at the outlet and a switch loop is added to a new switch. Watch the video to learn how to add a new outlet to an existing run.

For general purpose circuits you are only allowed 12 outlets on a 15 amp circuit and 16 on a 20 amp circuit. Here 3 wire cable is run from a double pole circuit breaker providing an independent 120 volts to two sets of multiple outlets. How do you tap an existing circuit to add an outlet for a flat screen tv. When an outlet receptacle falls in the middle of a circuit run rather than at the end there are generally two cables in the outlet box.

Arrangements are included to use an existing receptacle circuit or lights and switch circuits as the source for a new wall outlet.

Test the same outlet for absence of power using the tester.

The hot source wire is removed from the receptacle and spliced to the red wire running to the switch. This wiring is commonly used in a 20 amp kitchen circuit where two appliance feeds are needed such as for a refrigerator and a microwave in the same location. You then splice all the white wires and all the ground wires in the switch box together. Adding a new electrical outlet to an existing run is a straightforward process.

To add a new outlet to a group of receptacles already in place splice the new wires to one set of wires on one of the existing outlets.
