Configuration of Primary Main Distribution Box
Primary distribution systems consist of feeders that deliver power from distribution substations to distribution transformers. Expanded Radial System with Two Utility Sources and Multiple Primary Feeders shows an expanded radial system utilizing multiple substations and two utility sources, again with metal-clad primary switchgear but with a duplex metal-enclosed switchgear for utility source selection. Indication Lights: These provide visual availability and status of mains power supply. Together, they make sure the electrical power distribution box works well and safely. Smart DB boxes have extra parts like energy monitoring units and communication modules.

Where should the main power distribution box be placed on the construction site
The main distribution box shall be located in the area close to the power supply; the distribution box shall be installed in the area with relatively concentrated electrical equipment or load; the distance between the distribution box and the switch box shall not exceed. The power distribution system at the construction site shall be distributed in different levels. Choose the right box based on environment (indoor/outdoor), load capacity, and durability. Unlike residential or industrial panels designed for long-term installations, these boards are built for mobility, durability, and flexibility. This 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).
