How to Identify Electrical Circuit Failures
Electrical Question: I have three outlets in my kitchen, the breaker kept tripping and I thought my breaker needed to be replaced as I had one that actually did (now I believe it was my very old microwave (circa 1984) that was causing the tripping.
- The problem is this, after I replaced the breaker and now none of the outlets are working.
- I did take the old breaker with me to the store so as to get a correct replacement.
- There is juice coming from the breaker.They are on a circuit that went to an old 220v air conditioner.
- These outlets predate GFI, so none are GFI.

Home Electrical Circuit Repairs
- The problem with the described circuit was most likely not the circuit breaker, although at times circuit breakers do go bad, however solving problems with a circuit that does not have power requires a process of elimination.
- The first thing is to unplug everything from the circuit to see if the problem is with one of the appliances.
- This is a process that is best provided by a licensed electrical contractor which involves identifying and testing the circuit from the point of entry and throughout the circuit path.
- Once the problem is discovered the competent electrician will know how to make the repairs which are generally due to a bad connection with one of the wires, which is usually found at one of the device outlet receptacles.

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.
