Requirements for the distance of the on-site three-level distribution box from the ground
Distribution box and switch box should not exceed 30 meters. The Unified Facilities Criteria (UFC) system is prescribed by MIL-STD 3007 and provides planning, design, construction, sustainment, restoration, and modernization criteria, and applies to the Military Departments, the Defense Agencies, and the DoD Field Activities in accordance with USD (AT&L). The principle of minimizing distribution distances means that the distances between distribution boards and switch boxes should be kept as short as possible. It takes the incoming power and safely distributes it to different circuits throughout your building. Generally, distribution boxes can be divided into three levels of secondary protection, that is, three levels of distribution boxes: general. Dedicated space: The space equal to the width and depth of electrical equipment in addition to the space extending from the floor to 6 feet above the equipment or structural ceiling. IEC 60364 address residential premises.
