{"1":["What is the difference between an MCB and a fuse?","An MCB is a switch that automatically turns off the circuit during an overload or short circuit, whereas a fuse is a safety device that breaks the circuit when the current exceeds a certain level. MCBs are reusable, whereas fuses need to be replaced after they blow."],"2":["How do I know if my MCB or fuse needs to be replaced?","Frequent tripping of the MCB or blown fuses are common signs that it\u2019s time for replacement or repair. If circuits fail to work properly, or you notice overheating, it\u2019s time to check your MCB and fuses."],"3":["Can you install MCBs in an old electrical panel?","Yes, we can upgrade older electrical panels to accommodate modern MCBs, enhancing safety and functionality."],"4":["How often should I replace my fuses or MCBs?","MCBs typically last a long time, but fuses may need to be replaced more frequently, especially if they blow due to electrical overload. Regular inspection is recommended to ensure they are functioning properly."]}
