    The neutral should connect to ground someplace. In the US, by code, this occurs only one place, and that is in the circuit breaker panel. The neutral is treated as a live wire- because it...

    The pictures you posted are of an ABB of 86 HP, a baldor of 55 HP and another that looks equally large- or larger.

    There are advantages to having an oversize idler- but for a 7.5 HP load you are...

    OK, I will jump in and display my ignorance.

    I looked up D/C motor inrush current, and found that this was several times the running current.

    I looked up the overload relay, and it appears to...

    Yes, an actual experiment.

    I was not surprised that my 10 hp idler with caps generated some voltage. I was surprised that the voltage got up in the 250 range, and would run a coolant pump.

    So I was correct in post #10.

    That makes a much simpler RPC. If his electrical service is sufficient he can simply switch on power to a star wound 15 hp motor and generate the 3rd leg. If that...

    There are people who have motors they can spin with their foot or a rope, apply power and the motor will run whichever way they spun it, and generate 3 phase power for their machines. If somehow...

    OK, now it makes more sense.

    He had the balance caps in the system when he spun it up, so it was acting As a generator- the same as what I had done.

    On thinking on it a bit more, if your phases are 120 Degrees apart, I believe you could hook up your lines to two of the 3 connections for a wye motor and have it start on the application of...

    I had the second post on that thread. I actually did see a reduction in inrush current- after I removed the run caps from the system.
