Electrical Wiring Switch Loop - Mark the white wire at each end with black tape or black paint to indicate it is hot. Understand that switching is just a loop of the hot wire regardless of the colors of the wires. When the electrical source originates at a light fixture and is controlled from a remote location a switch loop is used. To make a switch loop connect the incoming hot black wire to the white neutral wire that runs to the switch. Connect the last switch in the usual manner looping the wire around the screw in a clockwise direction. Next the incoming white neutral wire is attached to the light fixture as usual and the black wire from the switch is connected to the light fixture. Electrical Wiring Switch Loop The black wire from the switch connects to the hot on the receptacle. The source neutral wire on the receptacle is removed and spliced to the white wire running to the switch and to a pigtail back to the receptacle neutral.
Electrical Wiring Switch Loop - It doesn t matter it s in the past. A switch loop is created when power is fed to a light fixture and the hot wire is broken and extended to a light switch. This circuit is wired with a 2 wire cable running from the light to the switch location. The bottom half of the receptacle is controlled by the wall switch while the top half is always hot.

Electrical wiring switch loop - To connect the switches simply score the wire with your wire stripper and push the insulation to expose about 3 4 in. Instead of running a separate pigtail from the hot wire to each switch just leave the hot wire extra long. Switch controlled split receptacle switch at end of cable run use this switch loop layout to control a split receptacle see circuit wiring 7 from an end of run circuit location.
The keys to using existing switch wiring. The neutral from the source is connected directly to the neutral terminal on the light and the source hot is spliced with the white loop wire. The hot source wire is removed from the receptacle and spliced to the red wire running to the switch.
The source is at the outlet and a switch loop is added to a new switch. Identify the location of the power source which means both the hot and the neutral and the ground of course. Figure 1 2011 nec handbook the common method prior to the implementation of the 2011 nec code of physically installing a switch loop was to use standard 14 2 cable which contains a white and black colored wire.
In the old days pre 2011 code adoption national electrical code said that if a wire with white or gray insulation or a marking of three white or gray continuous stripes is used as part of a switch loop to single pole 3 way or 4 way switches. Requires two wire and three wire cable.
