FAQ

 

Q1: How do I know if my fuse box is grounded?

A1: The simple way to find out is to use a volt meter and put the red lead in the hot side of the outlet or touch it to the black wire. The other lead touch it to the metal box. If you get a reading of around 110 to 120 volts it’s grounded.

 

Q2: Can a breaker box explode?

A2: If the circuit breaker won’t reset, and trips instantly, then you probably have a short in the circuit. This is a more complicated and serious reason for a breaker tripping because it can result in an excessive electric current that can potentially cause circuit damage, overheating, fire or even explosion.

 

Q3: What happens when you put a 20 amp receptacle on a 15 amp circuit?

A3: 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.

 

Q4: What is the largest size copper wire allowed on a 15 amp breaker?

A4: In a way, it all starts with the size of the wire. 14-gauge wire is the smallest allowed for the permanent wiring of a circuit. It is rated as able to carry up to 15 amps of current. 12-gauge wire is the next size larger and is allowed to carry up to 20 amps.

 

Q5: How far can you run a 20 amp circuit?

A5: The total circuit would be about 60 -70 feet in length. It would only be supplying about 5 outlets and one light. It would be a light load, running small things, no heaters or med/large equipment. #12 provides reasonable performance up to about 100′ with general loads like you describe.
