Learn the correct sequence: LV off before HV, control before main, and never operate isolators under load. Power Off and Power On Sequence in the Distribution Room When de-energizing, first disconnect the low-voltage (LV) side, then the high-voltage (HV) side. First open all LV branch circuit breakers, then open the LV main breaker. When an overload or short circuit occurs, the breaker rapidly interrupts the flow of electricity, preventing conductors from overheating and potentially starting a. Phase 3's Powersafe Sequential Mating Box controls the connection sequence of incoming / outgoing high current cable connections. With key (included) turn the Earth lock clockwise. These switches are responsible for protecting the electrical circuits from overloads and short circuits. By referring to the wiring diagram, you can easily identify which circuit. Connection method: Each switch takes a wire from the incoming point and connects it to the incoming end of the switch, or uses parallel connection to reduce the difficulty of wiring.
