Australian Standard Circuit Breaker Sizes Chart

The Australian Standard Circuit Breaker Sizes Chart is a table that lists the standard sizes of circuit breakers for use in Australia. The chart is divided into two sections: residential and commercial. The residential section lists the sizes of circuit breakers for use in homes and other small buildings, while the commercial section lists the sizes of circuit breakers for use in businesses and other large buildings.

The chart is based on the Australian Standard AS/NZS 3000:2018, which is the national standard for electrical installations in Australia and New Zealand. The standard specifies the minimum size of circuit breaker that must be used for a given application. The size of the circuit breaker is determined by the amount of current that the circuit is expected to carry.

The Australian Standard Circuit Breaker Sizes Chart is a valuable tool for electrical engineers and other professionals who work with electrical installations. The chart can be used to quickly and easily determine the correct size of circuit breaker for a given application.

The following is a table of the Australian Standard Circuit Breaker Sizes Chart:

| Application | Minimum Circuit Breaker Size (Amps) | |---|---| | Residential | 6 | | Commercial | 10 | | Industrial | 20 |

It is important to note that the Australian Standard Circuit Breaker Sizes Chart is only a guide. The actual size of the circuit breaker that is required for a given application may vary depending on the specific conditions of the installation. Always consult with a qualified electrical engineer to determine the correct size of circuit breaker for your application.
