Home / Standard Configuration of Level 3 Distribution Boxes on Construction Sites
Level II required configuration: Main circuit general isolation + main circuit fuse and circuit breaker Shunt isolation + shunt fuse and circuit breaker Level III configuration: isolation + leakage protectorLevel II required configuration: Main circuit general isolation + main circuit fuse and circuit breaker Shunt isolation + shunt fuse and circuit breaker Level III configuration: isolation + leakage protectorThis fact sheet explains how to apply the requirements shown in AS/NZS 3012:2019 Electrical installations – construction and demolition sites (AS/NZS 3012:2019), which is called up as a mandatory standard by section 163 of the Work Health and Safety Regulation 2025 (WHS Regulation). The distribution box (cabinet) is suitable for temporary power supply at the construction site and should meet the requirements of "three-level power distribution, two-level leakage protection, one machine one switch, one leakage one box" for power distribution and protection. These guidelines provide you with information on the installation of electricity mains, services, streetlamps, and other parts of our electricity networks.
