Switch Wiring Problems
Electrical Question: When installing a switch for a garbage disposal the power was on and the white wire grounded and tripped the breaker for the entire house.
- I capped the wires to finish the install.
- Now the outlets in the kitchen do not work.
- There is power to each outlet, but when I plug in a light to any of the outlets the light will not work.
- This home is in Illinois so everything is in conduit.
How do I locate the problem? After reading about this it appears that a neutral wire has come loose or burnt in the conduit.
This electrical wiring question came from: Edward, a Homeowner from Schaumburg, Illinois.
Thanks for your electrical wiring question Edward.

Common Problems When Wiring Switches and How to Fix Them
IMPORTANT: When replacing a faulty switch it is best to work only with the wires that are connected to the switch and do not disturb the other circuit connections.
Troubleshooting Circuit Wiring Problems
The following is a guide to help troubleshoot complex problems with circuit wiring problems:
- Identify the Circuit Wires
It is essential to identify the circuit wiring to avoid incorrect electrical connections.
- Identify Circuit Problems
An insulated wire will not burn inside of a conduit unless there is a problem with the circuit wiring and incorrect circuit breaker protection.
- Identify the Circuit Connections
If some of the wires have become disconnected, it is essential to identify and understand the circuit before the wires are capped off.
- Testing Circuit Devices
Test all the GFCI outlets and other devices of the same circuit and replace any that prove defective. When a circuit short to ground occurs there is a possibility that the short may cause a GFCI outlet to be damaged.
- The Panel Circuit Connections
The circuit wiring should be checked at the panel, including the connection of the neutral wire to the neutral terminal strip to make sure it is not burnt and the connection is tight and secure.
- Check Connections at Junction Boxes
Inspect any splices that are in the junction box where you were working. Restore the original circuit connections.

The Safest Way to Test Electrical Devices and Identify Electric Wiring!The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester, [amazon.com], I use for the detection of Standard 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.
