Identifying and Repairing Electrical Wiring
By Dave Rongey - Summary:|
How to Identify Junction Box Electrical Wiring. A tester or meter may be used to identify the electrical wiring that may be found in the junction box.
Using a Tester to Identify Electrical Wiring
- I can connect the wires to get power to lights and outlets but the switch no longer works and if I connect one of the wires with the power wire and others it trips the breaker.
- How should this configuration be wired?
This electrical question came from: Joel, a Handyman from Kings Mountain, North Carolina.
Thanks for your electrical wiring question Joel.
How to Identify Junction Box Electrical Wiring
Skill Level: Intermediate to Advanced
Tools Required: Basic Electricians Pouch Hand Tools and Voltage Tester or Continuity Tester
Estimated Time: Depends on experience and level of problem solving skills.
Precaution: Testing live wires is dangerous and should be done by an experienced individual only. Testing using a continuity tester should only be made after the circuit has been identified and turned OFF and Tagged.
The Process to Identify Electrical Wiring
- All of the wires in the junction box will need to be identified to fully understand how the wiring should be connected.
- It may be found that power is being fed through this junction box to power other light fixtures or outlets.
- The cable leading to the wall switch must be identified for proper connection.
- The wiring is best identified using a continuity tester.
Testing the Wires
A tester or meter may be used to identify the electrical wiring that may be found in the junction box and it is typical to find the following cable pairs in a fixture box:
- The incoming power source of the circuit.
- Outgoing power to other devices of the same circuit.
- Wire pair used for switching.
