![]() The load itself conducts current down the line to the subsequent loads in the circuit. In a series circuit, current must pass through a load at each device. But, in fact, all household receptacles are always wired in parallel, and never in series. It's common to describe household wall receptacles that are wired together using the device terminals as wired in series. The white wire is capped with a wire nut in the new switch box. The red wire from the switch loop is connected to the hot terminal on the light and at the other end to the new switch. At the fixture, the white connects to the neutral terminal on the light. At the switch, the black wire is connected to the new switch.īack at the source, the neutral wire is spliced to the white wire running to the light and to a pigtail connecting back to the receptacle neutral terminal. At the light fixture box, the black wire is spliced with the black wire running to the switch. The switch loop is a 3-wire cable to comply with NEC requirements of a neutral in all new switch boxes.Īt the receptacle, the always-hot wire is spliced to the black wire on the light fixture cable, and to a pigtail that connects back to the hot terminal on the wall outlet. New cable is run from the receptacle to the new fixture location and a switch loop cable is run from there to the new switch location. This drawing shows the wiring for adding a new light and switch with the fixture coming first in the circuit. Wiring a New Light and Switch Loop from an Outlet At the light, the black wire connects to the hot terminal on the fixture and the white connects to the neutral terminal. ![]() The white wire from the receptacle is spliced to the white wire going to the light, it doesn't connect to the switch in this diagram. Likewise, the source hot is removed from the receptacle and spliced to the new black wire and a pigtail connecting back to the hot terminal on the outlet.Īt the switch, the black wire from the outlet is connected to one terminal on the switch and the black wire running to the new light is connected to the other. The neutral for the new light is taken from the receptacle and spliced to the new white wire and to a pigtail that connects back to the receptacle. From the switch, new 2-wire cable is run to the new light location. The switch comes first in the new part of the circuit and new 2-wire cable is run to it from the outlet. In this diagram power is taken from an existing wall outlet for a new switch and light fixture. Wiring a New Switch and Light from an Outlet ![]() Also, find a diagram for adding a light from a switched receptacle you already have to include the fixture when you turn on the outlet power. Different wiring arrangements are included to allow for either the light or the switch to come first in the circuit. On this page 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. For wiring to add a new wall outlet see these. Individual to neutral and common to line.This page contains wiring diagrams for adding a new light fixture to an existing circuit. Individual lampholder wires (blue and red) are connected to line.Ĭommon wires (yellow) are connected to neutral. Similar sized wire connectors can be used. Trim wires to about 1/2” for neutral and 5/8” to 3/4” for line. Using tan wire connector for line and orange wire connector for neutral. Remove the ballast from the fixture (or leave it in place).
