Power and lighting distribution
The cabinet provides an enclosure for the selected switching and protective devices. The number of outgoing circuits, phase arrangement, protective-device ratings and metering functions are defined from the load schedule. Power and lighting circuits can have different requirements and should be identified separately.
Specify the enclosure and connections
State the available installation space, cable entry direction, operating access and the environment inside the electrical room. The final dimensions and internal arrangement are determined from the selected devices, conductor sizes and installation requirements. Additional enclosure protection should be agreed as a specific configuration.
Information for Selection
