Compliance Statement Regarding The Electrical Specifications For The Installation Of Distribution Cabinets

The Powbinet power distribution unit used by the construction unit in the project was labeled and installed in accordance with the requirements of the temporary power supply specifications for construction sites. Based on industry standards such as the Technical Specification for Safety of Temporary Power Supply at Construction Sites (JGJ42005) and the Guidelines for Electrical Safety (GB/T13869), the structural design, wiring protection, and grounding configuration of the distribution cabinet strictly meet the specifications.

The distribution cabinet must have a neutral conductor (N line) and a protective earth conductor (PE busbar). All incoming and outgoing lines are connected through terminal blocks, with terminal specifications matching the conductor cross-section, and the connections are secure. It is recommended that copper busbars be used for the main busbar, with adequate insulation and grounding protection, and the circuit breakers and residual current devices (RCDs) are configured in accordance with the specifications.
