One probe should be inserted into the ground wire, and the other into the positive hole of the socket. Make sure your circuit or cables are dead.

How To Identify Hot Wire.

Before testing the live wires, try it on a fixture. Turn on your multimeter and set it to measure voltage (v) under the alternating current (ac) setting. Before testing an unknown fixture, test a fixture that is known to be working.

And Observe The Voltage Reading.

Within this function, several numbers indicate the different ranges of voltage. Connect the probes to the meter and power it up. Make sure the switch is on;

There Are Several Ways To Test If A Wire Is Live.

By inserting your multimeter’s black probe into the live wire, you will get an indication on its display that the voltage is more than zero. Make sure your circuit or cables are dead. Typically there will be more than one setting within the range, so you'll want to choose the setting that is.

For Testing, Put The Red Probe Into The Live Wire.

In the simplest form, your multimeter will beep and alert you that the wire you are testing does indeed have power flowing through it. While keeping one lead on the ground terminal, touch the second lead onto the other live terminal or wire. If it is in the vicinity of the supply voltage, one of the wires is the 'live'.

It’s A Good Idea To Put One Probe In The Positive Hold And The Other.

On the meter it will likely look like a capital v followed by a ~. It has the advantages of being inexpensive, not requiring a battery, and. Test the wire using a multimeter
