Can you megger an electric wires? The megger will generate a current between the probes, and the meter will record the resistance of the jacket to the flow of the current. … Look for a resistance reading between 35 and 100 megohms. Acceptable insulation resistance values for electrical cables is 1 megohm per 1,000 volts of electricity.
How do you test a house wiring with a Megger? If you are testing insulation resistance to ground, place the positive probe on the ground wire or the grounded metal junction box and the negative probe on the conductor or terminal. Energize the Megger for 1 minute. Read the value of the resistance at the end of the minute test and note it in your table.
Can you test insulated wires? Insulation resistance testing is a key test for electrical cables as it is a measure of how effectively the cable is insulated. Poor insulation may result in short circuit, electric shock or fire.
What is a good Megger reading for wire? If the megger reads a resistance under 1 (1,000 ohms) on your meter after the initial 60-second interval, the cable has failed and the cable should be removed. If the megger reads a resistance between 1-1.25 on your meter, then the cable passes. Any reading above 1.25 is considered excellent.
