WYE POWER

In simple terms in reference to a three-phase system, it would be a five-wire system (three hot wires, a neutral

wire, and a ground wire) . A wye connection utilizes a star connection . Measuring voltage on a wye system will

give you around 120v to ground on all three hot legs or between 208-240v when measuring between hot legs .

NEMA TYPE 1

This is an indoor rated enclosure that is providing protection to the equipment inside from typical indoor

contaminates such as dirt or other solid falling objects .
