Hands must be dry when plugging and unplug g flexible cords and cord- and plug-connected equipment. Energized plug and receptacle connections must be handled with insulated protective equipment. Locking-type connectors must be properly secured after connection. Electric Power and Lighting Circuits Devices specifically designed as disconnecting means must be used for opening, reversing, or closing circuits under load conditions. Cable connectors (not of the load-break type), fuses, terminal lugs, and cable splice connections may only be used for such purposes in emergency situations. Circuits may be reenergized manually only after it has been determined that it can be done so safely. The repetitive manual reclosing of circuit breakers or reenergizing of circuits through replaced fuses is prohibited. Over current protection of circuits and conductors may not be modified beyond that allowed by installation requirements. Test Instruments and Equipment Only qualified persons may perform testing work on electric circuits or equipment. Test instruments and equipment must be visually inspected for defects before use, and be rated for the circuits and equipment to which they will be connected and the environment in which they will be used. Damaged or defective instruments and equipment may not be used until repairs have been made, and the items have been made safe. Flammable Materials When flammables are present only occasionally, precautions must be taken to prevent a hazardous condition from developing. When they are present on a routine basis, electrical installations must be made in accordance with OSHA regulations.
