I had a call that an aerator (480v) wasn't working, the operator said it tripped the day before and he reset. And it didn't come back on. When i got there I turned it off and the starter dropped out????!!!!, after being on all night. I ohm'd out the wires at the starter and they checked ok. Checked the amps, all legs were reading 15 amps (normal for it without a load) so I assumed the prop came off. pulled it and two legs had worn into about midways of the power cable. So, it had been on for at least 16 hours and never tripped with only one leg feeding the motor!!!!!!!! Put a new cable on and the motor is fine. How can this happen? it Should have tripped again, or burned the motor up, it shouldn't have read a complete circuit , or showed same amps on every leg. I'm kinda baffled with this.
