Testing Wire Installations After the conductors have been installed in conduits or raceways, it is accepted practice to test the installation for grounds and shorts. This test requires an ohmmeter, which not only measures resistance in millions of ohms but also provides a high enough voltage to ensure that the insulation will not break down when rated line voltage is applied to the conductors. Most ohmmeters operate with a maximum voltage that ranges from 1.5 volts to about 9 volts depending on the type of ohmmeter and the setting of the range scale. To test wire insulation, a special type of ohmmeter, called a MEGGER, is used. The MEGGER is a megohmmeter that can produce voltages that range from about 250 to 5000 volts depending on the model of the meter and the range setting. This instrument contains a hand crank that is connected to the rotor of a brushless AC generator. The advantage of this particular instrument is that it does not require the use of batteries. A range-selector switch permits the meter to be used as a standard ohmmeter or as a megohmmeter. When it is used as a megohmmeter, the selector switch permits the test voltage to be selected. Test voltages of 100 volts, 250 volts, 500 volts, and 1000 volts can be obtained. MEGGER can also be obtained in battery-operated models. These models are small, lightweight, and particularly useful when it becomes necessary to test the dielectric of a capacitor. Wire installations are generally tested for two conditions, shorts and grounds. Shorts are current paths that exist between conductors. To test an installation for shorts, the MEGGER is connected across two conductors at a time. The circuit is tested at rated voltage or slightly higher. The MEGGER indicates the resistance between the two conductors. Because both conductors are insulated, the resistance between them should be extremely high. Each conductor should be tested against every other conductor in the installation. To test the installation for grounds, one lead of the MEGGER is connected to the conduit or raceway. The other meter lead is connected to one of the conductors. The conductor should be tested at rated voltage or slightly higher.
