A typical source of power would be from an existing wall outlet in the same area or room.
Get power from light switch.
If power comes into the switch box first the neutral white line from the service panel and the white line that leads to the light are spliced together.
The switch will pass the electricity from the panel to a light or ceiling fan whenever the light switch.
Run 14 2 with ground sheathed electrical cable from.
The switch serves to cut the power from reaching the light switch.
If the power comes to the light outlet first and then goes to the switch then this can be done fairly easily as long as the outlet is accessible isn t too full of wires already because the unswitched power is available as well as the switched wire that is connected to the light.
You just want to put power to the switch then onto a light.
In this application the gfci outlet has the power entering the line side and extends through the gfci outlet and is fed out to the circuit from the load side of the gfci outlet.
This wire is needed to complete the circuit.
Turn the power off at the breaker.
You do not want the switch to control the outlet.
The ground wire sometimes in a green jacket should be connected to your switch and to your lights.
Flipping the switch interrupts the flow of electricity to the light turning it off and on.
The white or neutral wire bypasses the switch and goes straight to your lights.
The hot black wire from the power source travels through the switch and from there to the light.
The answer to this depends on how the existing circuit is wired.
Electrical switches typically have 110 volt power connected directly from the circuit panel.
