You use a device called a megger or meg ohm meter. Have the voltage range of the megger set to the working voltage of the motor. The first test should be to ground. One lead on the frame of the motor , the other lead one of the 6 wires. Test all 6 wires. If no ground shows up, test the individual coils against one another. If the coils are not grounded together, the motor is safe to energize.

Why and how does insulation depend on voltage?
Where you find wire insulation with ratings of 300 volts, 600 volts and 1000 volts, these are the highest allowable voltages that can be applied. A wire that is rated for 300 volts is good for 120 volts, 240 volts and 277 volts. At test research facilities, insulation on a wire is tested to destruction. The label that is given to wire's insulation, as a result of the tests, is the highest safest voltages that can be applied to that particular wire. So when you see a wire that has a label stating that it is rated for 300 volts it means that any voltage under and up to 300 volts is safe to apply.
Is there a voltage carrying limit of wire?
Yes it depends on many variables such as what the wire is made of the size of the wire whether the wire is a multi strand wire. What governs the amount of voltage a wire can carry is the insulation that is wrapped around the wire. Like wire with ratings of 300 volts, 600 volts and 1000 volts these are the highest allowable voltages that can be applied. A wire that is rated for 300 volts is good for 120 volts, 240 volts and 277 volts. At test research facilities, insulation is tested to destruction.

Which plastic is used for making wire insulation?
Electrical insulation on a wire or cable composed of plastic. Most wires and cables use plastic insulation. Some other types of insulation used on wires and cables are: enamel, cloth, natural rubber, gutta percha, ceramic, etc.
What does it mean when motor ticks?
i have a metal sleeve over each spark plug wire at the motor.....cant get the wire out to get to the plugs?? how do i get the wire off the plug??
Why do a megger test?
A megger test is done to check the insulation factor of wires or devices. This is to make sure that when the working voltage is applied, a short circuit to ground will not occur due to a problem with the insulation of the device or wire.
Why not use an ohm meter to measure the leakage in wire insulation?
An ohm meter measures resistance in a circuit, not leakage in wire insulation. To measure insulation resistance or leakage in wire insulation, you would typically use a megohmmeter or insulation resistance tester, which applies a higher voltage than an ohm meter to test the integrity of the insulation.
The term magnetic wire indicates a wire that has what for insulation?
Magnetic wire has a coating of varnish for an insulation.
What is the best test for testing battery cables?
Look at it. If the wire is corroded and/or the insulation is bulging, replace the cable.
What size of wire need to test using megger?
A general guideline is to use a megger that applies a voltage approximately twice the insulation's operating level. For example, for testing wires with an insulation rated for 600V, a megger with a 1000V output is commonly used. Always refer to the manufacturer's guidelines and specifications for the specific wire being tested.
What is the action of removing the insulation from wire?
The action of removing insulation for a wire is called stripping.
Why insulation is not required in winding wire side by side in motors?
Actually it is insulated, the red coating of varnish is the insulation. Also after a motor is wound, it is soaked in varnish and baked giving it added protection.
What is the high pod test?
A high pot test is a test of a wiring system for high potential (voltages). It's also called a megger test. This test verifies the integrity of a wire's insulation, and ensures that high voltages cannot escape through cracks in the insulation smaller than the human eye can see.

Does copper wire insulate?
The insulation on a wire is applied after the wire is drawn to size.

What is the outside of a wire called?
Insulation?
Electrical wire with clear insulation which wire is hot?
In standard electrical wiring, the black wire is typically the "hot" wire carrying the current, while the white wire is the neutral wire returning the current. If the wire has clear insulation, it may be difficult to distinguish between the two visually. It is best to use a voltage tester to determine which wire is hot.
