Fire Resistant Panels and Motor Manufacturing

06/30/2009 2:57 AM

In india, why fire fighting panels and chiller don't have neutral connection?. i.e., they are 3phase 3 wire connections.

why do some motors are 3phase - 3 wire and others are 3 phase-4 wire.? what is the criteria for manufacturing?

regards

The question is not nation-specific.

Fullest information on this topic may be gleaned from the Wikipedia article on 3-phase power.
