Equipment Use - Electric Power and Lighting Circuits |

|
Equipment should only be used for its designated purpose. Load rated
switches, circuit breakers, or other devices specifically designed as disconnecting means
shall be used for the opening, reversing, or closing of circuits under load conditions.
Cable connectors not of the load-break type, fuses, terminal lugs, and cable splice
connections may not be used for such purposes, except in an emergency. After a circuit is de-energized by a circuit protective device, the circuit may not be manually re-energized until it has been determined that the equipment and circuit can be safely energized. The repetitive manual re-closing of circuit breakers or re-energizing of charged circuits through replaced fuses is prohibited. Overcurrent protection of circuits and conductors may not be modified, even on a temporary basis, beyond that allowed in standard 1910.304(e), the installation safety requirements for overcurrent protection. |
