In most circumstances, besides what I've already stated, a… Read More

### What size circuit breaker should be used if you use 5 horsepower of air-conditioning?

To answer this question a voltage value must be given. Circuit breakers protect the conductors that feed the load. The lower the voltage value, the higher the current value, hence a larger the wire size is needed and therefore larger the breaker size for the circuit. In reverse the higher the voltage value, the lower the current value, hence a smaller the wire size can be used therefore smaller the breaker size for the circuit.

Legally there is no law on this (under UK law) However, you will know if there are too many as this will cause the breaker to trip 'breaking' the circuit, and thus telling you there are too many =============== In the US, circuit conductor size and circuit breaker size are calculated before installation. If you are doing modification you should get the help of a professional in calculating what your installed wiring will safely allow.

### What is the use for a circuit breaker?

Each wire size is rated to carry a specific amperage. A circuit breaker is used to limit the amount of amperage that can be applied to these specific wire sizes.
