How to Identify Electrical Wiring for Lighting Circuits
[ad#block]Electrical Question: I have two separate switches. One controls a ceiling fan, and one goes to a switch controlled outlet.
The power comes into the switch that controls the outlet. This was once a three way switch, but no more. I have switched out the 3-way switches for single. I am trying to use the red wire of the existing 3-wire to extend power to the switch box that controls the ceiling fan, and then provide power to the fan through the switch. All seems to work fine until I turn off the switch that controls the outlet, then it trips the breaker.

Circuit Testing to Identify Electrical Wiring

Identifying Electrical Circuits

From what has been described it is very possible that there are actually two circuits that are found in the switch box, and that you have tied into these two circuits to be used where one circuit is needed.
A voltage tester is required to identify these two circuits so that each circuit may be isolated to its own separate function and remain separate from the other function.
These two circuits may be part of a multi-wire circuit.
Switch wiring such as this can be complicated and is best identified by a qualified electrician.

Electrical Tips

To Help You Wire it Right

The Safest Way to Test Electrical Devices and Identify Electric Wires!
The Non-Contact Electrical Tester

This is a testing tool that is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.

The Quickest Way to Check for Faulty Electrical Wiring!
The Plug-In Outlet Tester

This is great to troubleshoot a problem with outlet circuit wiring, is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect, Very handy and easy to use.

Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!
The Wire Stripper and Wire Cutter

A wire stripping tool used to safely strip electrical wires. This handy tool has multiple uses: The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation. The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets.
