What does the 15 and 20 mean on a circuit breaker?
The standard for most household circuits are rated either 15 amps or 20 amps. That means a 15-amp circuit breaker can handle around 12-amps and a 20-amp circuit breaker can handle about 16 amps.
How do I choose a circuit breaker size?
The general rule of thumb is that circuit breaker size should be 125% of the ampacity of cable and wire or the circuit which has to be protected by the CB….According to the ohm’s law,
- I = P / V.
- I = 2000W / 120V.
- I = 16.66 A.
How do I know what size breaker box I have?
Look at the amperage rating on your main breaker or fuse, which may or may not be located in your electrical service panel with your other breakers or fuses. The main breaker will usually be the largest breaker you have and should have its capacity written on it or adjacent to it.

What happens if a bulb blows in a series circuit?
If one bulb burns out in a series circuit, then this will break the circuit. Unlike in a parallel circuit – where each light has its own circuit – so even if one bulb burns out, the remaining bulbs will still function.
