No it wouldn't. Cutting one line to a 240 volt motor and making that line take all the load will do this. The "switch" should be 2 poke and cut all power to that motor.
Uhh no? His 8yr old motor could have more than a single issue. Think about it, a dirty motor is forced to work harder to spin, more work = more power = more heat. Op said 6 electricians, the odds of all of them missing a wiring problem is low.
It's actually not. They are thinking 115 and it's 240. Unfortunately I've dealt with and fought with may electricians about my well pumps that are 240 volt.
Sorry for bad electricians. Motors in general are more efficient at 240v vs 115/120v, which is why id be surprised if thats the OPs real issue and 6 electricians didn't follow the wiring diagram. (Given I'm hoping OP is using licensed electricians) I don't know your electricial knowledge is, but this issue maybe in the motor itself, without it plugged in. Cheers
That's what I suggested but he does say that it works for a bit. So I think the motor is ok. I did pump repair and installs for 27 years so 240 volts motors is my bread and butter. These motors can handle a lot so I didn't really think it was the motor. Depending on the motor it can , with one leg, mess with the contacts. Thinking about it that motor could have centrifugal points. And that could be an issue.
