Construction Site Power Distribution Cabinets And Construction Power Supply Specifications

The layout of the Powbinet system at the construction site should revolve around the hierarchical power distribution structure of the construction power system. In practice, the location of the distribution cabinets, the selection of electrical components, and the wiring methods must all comply with the construction power standards issued by the construction department. Labeling should include incoming and outgoing line identification, voltage level, circuit number, and leakage protection information to meet the inspection requirements of on-site construction and subsequent acceptance.

Matching the distribution cabinets with the construction power specifications also involves the internal terminal blocks, neutral (N) wire, and protective earth (PE) wire distribution within the distribution cabinet. Labeling the internal connections of the distribution cabinet according to the specifications helps on-site personnel quickly identify each circuit and its functional level. The labeling of different electrical components should comply with national and industry standards to facilitate on-site work coordination and technical verification.
