The main distribution board should be set near the power supply, where the power consumption equipment of the distribution box or the load is concentrated; When the distance between the distribution box and the switch box exceeds 30m, the switch box shall not. The power distribution system at the construction site shall be distributed in different levels.

Modern stadiums integrate photovoltaic (PV) solar arrays, battery energy storage systems (BESS), and EV charging infrastructure — all requiring advanced low-voltage distribution boxes capable of managing bidirectional power flows and reactive power compensation. Each stadium's power systems should be designed to suit the match and broadcast needs of the events it will host, from major international matches down to community stadiums for development groups. Power supplies will need to be resilient and incorporate redundancy in order to provide back-up. A Power Distribution Box (PDB) is a centralized electrical enclosure that receives incoming power from a main supply and distributes it safely to multiple circuits across a facility. In the context of city stadiums and Olympic projects, these systems are not merely utility components — they are. According to experts, during moments of peak demand on game days, the stadium is capable of consuming a staggering 10 megawatts of electricity. Design solutions to provide a category 1 or category zero power supply with two or three independent power sources via a 20kV or 1kV automatic standby system.
