How do you find out which outlet the light switch controls?

Answer 1

turn off circuits one at a time until one of the outlets you are concerned about goes off, and leave it off now check the OTHER outlets you are concerned about if any of the OTHER outlets are still alive, then they are on a different circuit

Answer 2

To determine which outlet a light switch controls, turn the switch off and test the outlets with a lamp or device. Once you find the outlet that loses power when the switch is turned off, you've identified the controlled outlet. Alternatively, you can use a circuit tester to trace the wiring and identify which outlet is connected to the switch.

Answer 3

Plug a table lamp into the receptacle and turn on the switch. Make sure that you do both the top and bottom positions on the receptacle Some times just the top half or bottom half of a duplex receptacle are switched and the other half is regular un-switched power.

Answer 4

Sometimes it is written on the door. One person disconnects the fuse while another person tell them when the power goes out. Some systems used two breakers in a room with overhead lighting on still another circuit.

Answer 5

Sure, but the new outlet will be restricted to the amps rating of the fuse for the original outlet. You're basically making a hardwired extension cord.

Answer 6

In parallel circuit
