Classification of Level 3 Distribution Boxes
Summary of Three-Tier Power Distribution System: Primary: The main distribution panel, supplies power from the transformer. Let's make a hypothesis: a newly built residential area introduces a 10kV incoming line and builds a distribution room. Classification by structural characteristics and application: (1) Fixed panel switchgear, often referred to as switchboard or. Primary power distribution： temporary electricity is in a place where the construction needs electricity, that is, from the transformer into the three-phase power supply, ground wire, neutral line. Secondary power distribution;：From the primary distribution box power line to the temporary power. 1) First-level power distribution equipment, collectively referred to as power distribution center. Equipped with larger three-phase circuit breakers. The final connection point for end-use devices, delivering 220V (single-phase) power. Designed for local control with strict safety standards, such as. It is specially designed for the special situation of the project construction site and meets the relevant construction power specifications and standards of the construction department.

National Testing Standards for Distribution Boxes
A cornerstone standard in this area is ASTM D4169, Standard Practice for Performance Testing of Shipping Containers and Systems. ASTM D4169 defines a series of tests and hazard levels to evaluate how a packaged product will endure a typical distribution cycle. It encompasses various test methods. ASTM's paper and packaging standards are instrumental in the evaluation and testing of the physical, mechanical, and chemical properties of various pulp, paper, and paperboard materials that are processed primarily to make containers, shipping boxes and parcels, and other packaging and labeling. Packaging serves a purpose far beyond aesthetics—it ensures that products remain intact and undamaged, whether they are being shipped across vast distances or stored for prolonged periods. As members of ASTM and ISTA, DDL's engineers are well versed in these sometimes difficult to understand test standards. Manufacturers, distributors, and retailers use ASTM standards to verify packaging durability.
