A rack unit (abbreviated U or RU) is a unit of measure defined as 1+3⁄4 inches (44. It is most frequently used as a measurement of the overall height of, as well as the height of equipment that mounts in these frames, whereby the height of the frame or equipment is expressed as multiples of rack units. For example, a typical full-size rack cage is 42U high, while equipment is typically 1.

Residual current protection (RSD/RCCB/RCBO): Detects leakage current and cuts off power to reduce electric shock risk. Earthing connection: Ensures proper grounding to maintain safety and system stability. Switches and Indicators: Some distribution boxes include switches for controlling circuits and indicator lights (like LEDs) to show the status of the electrical connections. Each enclosure is pre-wired, tested, and built to NEC standards, making it easier to deploy safe, compliant power distribution at job sites or.
