This Practice covers the general requirements for design, materials fabrication, inspection, testing, and shipping of medium-voltage motor control centers and also covers requirements for the design, fabrication, and testing of metal enclosed, NEMA Class E2 controllers. This equipment is used for the supply, control, and protection of medium-voltage motors.

The application of NEMA Class E2 controllers covered by this Practice is limited to squirrel cage induction and synchronous motors rated 5000 hp or less and limited to transformers of 5000 kVA or less. Where specific job requirements dictate, exceptions to this limitation may be taken with Buyer’s prior approval.
