	This would be the responsibility of the electrical contractor performing the task. Some real information will be needed by whomever does the work. The MPCB's would need to be large enough to protect the wiring.

	Read the label on the motor. It will tell you what voltage(s) should be applied and the running current it will draw. You should expect that the current will be higher when starting. The start current will briefly be the locked rotor current rating. There's a lot of information and code referencing that should be done when properly installing a motor, the associated wiring and protection circuitry. Let a professional handle this. __________________ "Don't disturb my circles." translation of Archimedes last words

	Locate a copy of British Standard 7671. Open at page 1. Read on. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856
