How do I check for electrical problems in my house?

How can you know that there is an electrical fault or problems in your house?

Just because your circuit breaker hasn’t tripped, doesn’t mean there isn’t a problem with your electrical wiring. Another symptom of out dated or damaged wiring is flickering, buzzing or dimming lights.

How do you troubleshoot electrical problems in your home?

Turn off all wall switches, and unplug every lamp and appliance on the dead circuit. Then reset the tripped breaker or install a new fuse as discussed above. If the circuit goes dead right away, the problem could be a short circuit in a receptacle or switch.

How can I test my home electrical system?

To safely test an electrical circuit, use a circuit tester (as shown at left and enlarged at right) to ensure that no electricity is flowing through it. If a receptacle is live, a neon tester’s bulb will light when probes are inserted into the slots.
