Arrangements are included to use an existing receptacle circuit or lights and switch circuits as the source for a new wall outlet. The hot source wire is removed from the receptacle and spliced to the red wire running to the switch. The neutral wire from the circuit is shared by both sets. 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.

Once power is verified turn off the electrical power to the wiring circuit. There are diagrams for adding lights to a ceiling fixture you already have and for using an existing wall outlet as the source for a new switch and light.

The source is at the outlet and a switch loop is added to a new switch. For general purpose circuits you are only allowed 12 outlets on a 15 amp circuit and 16 on a 20 amp circuit.

To add an outlet to a light switch you start by making a pigtail using the hot wire the wire going to the fixture controlled by the switch and a third length of wire.

Here we have an ideal situation the drywall on one side of the wall has been removed and the wiring is exposed. Test the same outlet for absence of power using the tester.

Here 3 wire cable is run from a double pole circuit breaker providing an independent 120 volts to two sets of multiple outlets.
