Thanks for your electrical tester question Debra.

Electrical Wire Locators and Circuit Tracers

Application: Electrical Troubleshooting and Repairing a Damaged Electric Circuit.
Skill Level: Advanced – Best performed by a Licensed Electrical Contractor.
Tools Required: Basic Electricians Pouch Hand Tools, Voltage Tester or Volt Ohm Meter and a Circuit Tracer.
Estimated Time: Depends on the type and age of the home, the condition of the electric wiring, and the access to the circuits and wiring to be evaluated.
Precaution: Identify the affected circuit, turn it OFF and then Tag it with a Note before performing any wiring or inspections or electrical repairs. Electrical troubleshooting and repairs requires specific tests of the electrical circuits.
Notice: Repairs to Home Electrical Wiring should be made according to local and national electrical codes. Installing new or replacement electrical wiring may require a permit and inspections.

    Hi Steve,
    Here are two methods of Electrical Circuit Testing that will reveal the condition of the circuit conductors.
    The circuits may be tested for Resistance using an Ohm meter, and tested for Load using a clamp on amperage meter. The results of each test must be evaluated according to the circuit wiring and the known connected loads. By performing an inspection of the circuit wiring, and factoring in the age, and the methods used during the installation you can almost determine what the test results may be. Abnormal electrical consumption or unusually high electric utility bills may be a sign of voltage leaks, which is bad in itself, but it also presents a great hazard with destructive capabilities, especially in moist conditions. Circuits that are thought to be damaged should be disconnected until they are properly repaired or replaced. Electrical circuit testing methods must be fully understood before proceeding. When working with electrical wiring there are risks involved which are escalated if the wiring is suspected to be damaged, therefore electrical wiring and electrical testing is best performed by a qualified electrician.
    I hope this helps with your circuit problems,

    Hi, thanks for being here. My electric bill seems to be about twice what it should be and I’m wondering if I don’t have a line leaking to ground somewhere. I have 2 separate circuits that go outside underground to a garage and one to a light pole. The garage line has been in place at least 40 years that I know of and spliced once. The light pole is only about 30 years old but could have been hit on a couple occasions while digging nearby. I was thinking about getting a meter to clip on each circuit at the breaker box and narrowing it down by circuit and then by appliance or outlet. What meter would be best for this? Am I on the right trackin this thinking about losing power to ground? The house is about 120 years old but I think all wiring has been replaced. Thanks.
