    In your first post of an issue, never tell us that something was tested and was "okay." Tell us about the test AND the specific results. Let us decide if the result is "okay." The more detail and train of thought you can share is all the better.

    Measure all phase legs for voltage and current. Do NOT measure voltage to ground. Give us the results. If the unit can run, check for voltage drop from line to load.

    If a unit cannot run. put good fuses in the disconnect, and with the feeders de-energized, measure resistance from the line to load terminals with the disconnect closed in.

    If you don't understand what the words "feeders de-energized" means, ask someone with more experience to help you right away, so you don't get hurt. This is not residential equipment, and many guys are seriously unprepared for this part of the business.

    Most of the time, your "entre" into this type of work needs to be done with an experienced person next to you, giving instruction AND asking you questions.

    This is NOT a part of the trade where you should be tossed in and asked to swim.

    I'd like to add a couple things to the list of requests:

    if you're having an issue with some type of overcurrent device.... whether it be a circuit breaker or fuses in a disconnect..... please also supply things like the wire gauge and a fuse or circuit-breaker setting, the unit's minimum circuit ampacity and the maximum overcurrent protection device values, which are given on the unit label.

    The more information you provide in a post, the more cogent and insightful will be the reply that you receive.

    Hey folks sorry for the time lag on a response. As someone stated it's motor time. Timebuilder; I apologize for the lack of info included in my post. I will be the first to admit that I don't know everything, I've been in the trade for about 14 years. However when I posted this thread I was at home thinking it through and when a lot of the questions were asked I didn't know exact values to the questions. That's my fault, I will chalk that up as lesson learned. Next time I post I will have more accurate readings instead of saying that it tested ok.

    Okay, motors away!

    Glad it worked out for you. I'm sure a lot of other people watching this thread learned something as well.

    Put 60 amp time delay fuses. Have fun and experiment. Perhaps the load holds back the shaft and the windings shift somehow on their mounting inside and short. I just made that up, ha ha, but who knows? Something has changed.
