Indoor electrical distribution boxes should be raised above the ground
Wall-mounted boxes should be 4. This height makes it easy to reach without bending or stretching. Check and fix the box often to prevent problems. The International Standards of Practice for Inspecting Commercial Properties (ComSOP) states that the inspector. According to the "Code for Acceptance of Construction Quality of Building Electrical Engineering" GB50303-2002, the vertical distance between the bottom surface of the fixed stainless steel enclosure ip67 and the ground should be greater than 1. The bottom surface. A distribution box is the heart of any electrical system. - The foundation should be inspected and accepted as qualified, and the conduits embedded in the foundation, transformer incoming and outgoing line reserved holes, and related embedded parts should be inspected and qualified.
