The Recommended Work Practices for Repair of Rotating Electrical Equipment guide describes record keeping, testing, evaluations, and general guidelines for the repair of electrical motors and generators. It is not intended to replace customer or manufacturer specific instructions or specifications.<\/p>\n\n\n\n

Excluded from the scope of this document are specific requirements, certification and inspection required for explosion-proof, dust-proof and other listed machines which are approved for hazardous environments as well as special or additional requirements for hermetically sealed motors, hydrogen-cooled motors, submersible motors, propulsion motors, or Class 1E motors for use in the nuclear industry.<\/p>\n\n\n\n
