An electrician and his apprentice were performing electrical maintenance on a 480-volt fused, load-rated circuit breaker. One of the employees used a screwdriver to remove a piece of metal from under one of the fuses. The screwdriver contacted the bus and the frame of the enclosure and caused a phase-to-ground electrical fault. A phase-to-phase electrical fault developed, and the ensuing electric arc burned both employees. They were hospitalized for their injuries. One was released 6 days later. The other employee was released the next day but had to return for skin grafts.
