If you are wiring up a Three Phase 230 Volt motor the wiring is different than for a
460 Volt Motor.
REF:
**broken link removed**
You MUST provide some protection, Fuses, Overloads, and such to have the proper
protection.....else the fire/sparks can fly, and you don't want that. This means you will
need a Motor Starter that contains Overloads and Fuses.
The three fuses should be sized to protect the wiring, and the Overloads should be
sized according to the motors service factor rating. If I remember correctly, for
Service factors > 1.00 you can size the overload for 120%. Otherwise the Overload
should be sized such that it is as close to the Nameplate current rating, but not over,
according the the overload charts. Starting current (6 times Lock Rotor) can be very
high, up to six times Lock Rotor so everything must be properly sized.
