Q1: What is VCB breaker?

A1: A vacuum circuit breaker is such kind of circuit breaker where the arc quenching takes place in vacuum. The technology is suitable for mainly medium voltage application. The material used for current carrying contacts plays an important role in the performance of the vacuum circuit breaker.

Q2: How do I know what circuit breaker I need?

A2: Circuit breakers have markings stamped on the side of them and are usually located inside the panel cover door. There is a label that will tell you what type of breaker is needed for installation in that particular panel.

Q3: Can I replace a breaker myself?

A3: You can replace the circuit breaker by just removing the panel cover. Once you have removed the cover then you can disconnect the wire from the faulty breaker and pull it out of the way.Take note of how the breaker fits in the panel and locks into position so that you can put the new circuit breaker in correctly.

Q4: Why does my breaker stay tripped?

A4: The only reason a circuit breaker trips is to stop the circuit from overloading and overheating more than what the circuit can allow. If your circuit does overheat, you will experience harmful problems such as damage to your electrical units and possibly a fire.

Q5: Do house breakers go bad?

A5: So to answer the question simply, yes, circuit breakers do go bad, the way any other essential home device can cease to work the way that it should. This being said, a faulty circuit breaker does not necessarily mean that it has to be replaced.
