May unqualified personnel reset a circuit breaker or replace fuses without having a qualified person investigate why the breaker tripped or the fuse blew?
In my opinion, that’s a very bad and dangerous idea. From my point of view, you should hire special people who will find out where the problem is and solve it. I am from New York and in my district, we often have problems with electricity. This fact pushed me to hire guys from Handykith every time when I had problems with electric things. They also helped me with circuit breakers installation and they did it well, I must admit
Reply: Paragraph (b)(2) requires an evaluation to determine whether equipment and circuits can be safely reenergized prior to operating a manual circuit protective device. However, as the “Note” advises, if employees can verify an overload condition from the de-energized circuit, then no examination is needed before the circuit is reenergized. In this situation, an unqualified employee could reset the breaker or replace the fuse once, if doing so would not expose the employee to electrical parts that are energized above 50 volts.
