Standard Circuit Breaker Sizes Australia

Standard circuit breaker sizes in Australia are determined by the Australian Standard AS/NZS 3000. This standard specifies the minimum and maximum sizes of circuit breakers for use in residential, commercial, and industrial applications.

The size of a circuit breaker is determined by its rating in amps. The amp rating of a circuit breaker indicates the maximum amount of current that the breaker can safely interrupt.

The table below shows the standard circuit breaker sizes for Australia.

| Circuit Breaker Size | Amp Rating | |---|---| | 10A | 10 | | 15A | 15 | | 20A | 20 | | 25A | 25 | | 32A | 32 | | 40A | 40 | | 50A | 50 | | 63A | 63 | | 80A | 80 | | 100A | 100 |

When choosing a circuit breaker, it is important to select a size that is appropriate for the load that the breaker will be protecting. A circuit breaker that is too small for the load may trip frequently, while a circuit breaker that is too large for the load may not provide adequate protection.

If you are not sure what size circuit breaker you need, it is best to consult with a qualified electrician.

In addition to the standard circuit breaker sizes listed in the table above, there are also a number of specialty circuit breakers available. These specialty circuit breakers include:

* GFCI circuit breakers: GFCI circuit breakers are designed to protect against electrical shock. They are required by law in all new residential construction in Australia. * AFCI circuit breakers: AFCI circuit breakers are designed to protect against arc faults. Arc faults are a type of electrical fault that can cause fires. * DDFT circuit breakers: DDFT circuit breakers are designed to protect against double-feed faults. Double-feed faults can occur when two circuits are connected to the same outlet.

When choosing a circuit breaker, it is important to consider the specific needs of your application. If you have any questions, it is best to consult with a qualified electrician.
