Insulation resistance test: This test is used to find the insulation resistance of motor for 1 min or 10 min through high voltage insulation tester. By this we can find the insulation level. Polarization index: This is the ratio between insulation resistance for 10 min to insulation resistance for 1 min.
The megger is used to find insulation resistance in any equipement. It will generate around 10kVA power to test.
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.
Good question. Lots of people would like to know that. When you find out, please let me know. A study buddy helps.

Get your book out study it thoroughly and take the test. If you dont pass it at least you have an idea of what is on it. <><> ---While I certainly agree with this answer, it's also important to note that there are a lot of things on the NCCER test for pipe-fitting that you will pretty much never run into in the field. With that, and the above statement, being said, there is a company called Contren that has a learning series for any craft in the NCCER certification series. Here's the link to the pipe-fitter's series in the Related Link below. The company is not called Contren. Contren is NCCER's copyrighted curriculum that they developed for trainees. It can be purchased through Pearson Publishing. here is the link to find it; http://nccer.pearsonconstructionbooks.com/store/browse.aspx?st=69118
