How a 3 phase motor starter works
WebElectrician: Franklyn. Okay, yes, I would go with the name plate and what it states. I would say that this unit should be wired as a single phase, 2pole breaker. Black and Red on the breaker and white on the neutral bar, ground on the ground bar in the panel. It would provide the 230-240v to the saw like it needs. WebPrinciple of Direct On Line Starter (DOL) To start, the contactor is closed, applying full line voltage to the motor windings. The motor will draw a very high inrush current for a very short time, the magnetic field in the iron, …
