FAQ

Q1: What causes a breaker box to catch fire?

A1: Outdated wiring often causes electrical fires. Breakers should be triggered when circuits get overloaded by too much electricity, but outdated breaker boxes often have worn connectors that do not work, causing the system to overload and start an electrical fire.

Q2: How many times can a circuit breaker trip?

A2: An electrician is coming to replace the cutoff (containing fuses) with a simple lever cutoff. In discussing this he said that a circuit breaker should not be allowed to trip more than 4 or 5 times before being replaced.

Q3: Can I put a 20 amp fuse in a 15 amp slot?

A3: The 15 amp slot is designed for handling current upto 15 amps so if you put a 20 amp fuse in a 15 amp slot and draw a current greater than 15 amps there will be heating and other issues like molten insulation you can put a 20 amp fuse only if u know that u are not going to draw more than 15 amps.

Q4: What happens when you put a 20 amp receptacle on a 15 amp circuit?

A4: If your question is “can I connect a receptacle rated for 20 amps to a circuit designed for 15 amps?”, the answer is yes, because the receptacle can handle more current than the circuit is rated for. If you exceed 15 amps, the breaker will blow, and protect the receptacle.

Q5: Are you a factory or trading company?

A5: We are a professional manufacturer. We are warmly welcome clients from worldwide to visit our factory and cooperate with us.
