OSHA Requirements Made Retroactive  Examination, installation, and use of equipment  Splices  Arcing parts  Marking  Identification of disconnecting means  Guarding of live parts 600 volts (V) or less  Grounding terminals and devices  Over current protection (600 V nominal or less)  Grounding systems, connections, path, supports  Grounding non-electrical equipment  Grounding methods for fixed equipment  Uses of flexible cords and cables  Splices for flexible cords and cables  …
