A Double Pole (DP) fuse disconnects both the live and neutral wires to protect the circuit during faults, such as overloads or short circuits. An MCB (Miniature Circuit Breaker) automatically cuts off the power in the event of an overload or short circuit. It is reusable and safer than a traditional fuse. 🔧Inspecting and replacing a faulty DP fuse or MCB: ✅Inspect the faulty DP fuse and MCB for any damage or malfunction. ✅Safely disconnect the power supply before starting any work. ✅Remove the damaged DP fuse and/or MCB and replace it with new components. ✅Ensure proper wiring and tighten all connections for safety and functionality. ✅Test and restore the power supply to confirm that everything is operating correctly.
