How to Determine if a pump is 240 or 120

[Haji]

If resistance is low enough to read without an insulation tester what more are you going to learn about the situation by using an insulation tester?

None, of course. But if it is high enough...........?

OP already indicated he was certain there was a ground fault.

OP already indicated he was certain there was a ground fault.

But he was not sure how many ground faults were there and so, again, the link at post # 11 may not be depended on.

Finding the status of 'degree' of grounding of phase leads of the (submersible) motor with an ohm meter may not be correct. An insulation tester is more appropriate for that.

If you get any reading from lead to ground with an ohm meter you're done, so is the motor. There is no need to do an insulation test.

You are also right.

Here in CA abandoned wells have caused serious problems when the casing eventually failed and allowed pollution from surface water or upper aquifer to get into a lower aquifer. Not an electrical problem but I feel strongly about the subject.

Thank you! We should all feel strongly about this. :thumbsup:
