When the melt is burnt out under short circuit, the sound is very loud, the melting part is big, and there is burning phenomenon in the melting tube. According to the cause of fusing, find out the fault point and remove it.

When changing the melt, the specification of melt should be suitable for the nature of load and line current.

When replacing the melt, the power must be cut off for replacement to prevent electric shock.

Our experts have rich experience in various fields, so we have to provide a wide range of professional solutions for customers in various industries to win competitive advantages for customers.

Q1: Where does the white wire go in a breaker box?

A1: If you're installing a standard breaker, the neutral (white) wire connects here, too. If you're installing an arc-fault circuit interrupter (AFCI) breaker, you'll connect the neutral to the breaker and run a “pigtail” wire to the neutral bus.


Q2: What is circuit breaker with diagram?

A2: A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current, typically resulting from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected,


Q3: Where does the ground wire go in a breaker box?

A3: For service entrance, in the United States, the ground wire is bonded to the neutral bus bar and to the ground bus bar—if present—or the can. You will often times find a breaker panel combined with service entrance hardware. In any sub-panel, the ground wire is bonded to the ground bus bar or the can.


Q4: Is a tripped breaker dangerous?

A4: A tripped breaker is often just a one-time annoyance, but it can indicate potentially dangerous problems with your home's electrical system. Older homes in particular were not designed to handle today's increasing electrical demand.


Q5: Can a circuit breaker be reset automatically?

A5: The circuit breaker can simply be reset following an interruption. This is why fuses are increasingly being replaced by automatic circuit breakers.
