4 Advantages of Using a Wire Tester in Your Home

A wire tester can be used for many purposes inside a home. It can be used for both  simple wiring repairs or more complicated projects, such as replacement and installation of main circuitry. Below are some of the advantages of using a wire tester in your home.

Detects Broken Wires

A wire tester can detect whether a wire is broken or not. Sometimes, circuits do not work because some wires are broken or damaged. When a wire is broken, current cannot pass through. To check for any broken wires, set the tester to read resistance. The resistance of the wire tells you if a wire is broken or not. Touch the probes of the tester on the wire and see if the tester displays a low or high resistance. Wires with high resistance are called open wires. These wires do not allow current to pass through because they are broken. If the tester reveals a low resistance, the wire is in good condition and is continuous.

Detects Live Wires

When repairing electrical circuits at home, it is best to turn off the power source. This means turning off the circuit breaker. Sometimes, the circuit breaker does not work and this poses a dangerous risk of electric shock when working with naked wires. To check if the wires are conducting electricity or not, it is best to use a wire tester. Set the tester to read current. Touch the two probes of the tester on the wire and see if it gives a reading. If the tester does not indicate any current, the wire is safe to touch with bare hands. If the tester detects current, make sure that the circuit breaker is repaired.

Detects Cross Lines

Cross lines are not only dangerous, but they also waste a lot of electrical energy. If you are moving to a new home, it is best to check for cross lines. A cross line is a connection made between two circuits. Normally, connections should be isolated in order to provide efficient use of electrical power. A wire tester can detect these cross lines.

Reads Voltage, Amperage and Resistance

A wire tester can also be used for simply reading the voltage, amperage, or resistance of wires in a circuit. To ensure that an electrical outlet has the right amount of voltage, the probes on the tester can be connected to the sides of the outlet to determine the amount of voltage on the connection. The tester can also read the resistance of a wire. It also reads the exact amount of current passing through wire. These values are very important when doing electrical repairs on a home circuit or electrical home appliance.

You don't have to be a licensed electrical technician to own and use wire tester in your home. In fact, every home should own one that adults in the household can use. It will not only save you the trouble of knowing which wires are damaged or in working condition, it will also save your family from the dangers of getting electrocuted by seemingly harmless, broken wires.
