I have a commercial crac unit going off on hi head, internal ol. I megged out 1 comp at 500v and got 170 on the 3 legs. I megged out comp at 500v 2 and got upwards around 385 on the legs. Im used to using the push button supco meter and looking to keep it in the green. Now i have a fancy meter that shows numbers. Can someone give me a crash course on megging numbers? Now to think of i, i should have used the higher voltage. (1000v) and run the test again. I pulled the fuses and am running on 1 ckt. Any help is apreciated.
