Essential Rules for 3-Level Electrical Distribution
The main distribution board should be located near the power source. Distribution boards should be placed in areas where electrical equipment or loads are

Here's a quick rule of thumb using a three-phase 400V system: Power (kW) = √3 × 400V × I (A) × PF (0. 8) Always keep a 10–20% margin for surge and future expansion, especially in prefab room power applications. (1) Power distribution from the primary main distribution board (distribution cabinet) to secondary distribution boards can be branched; that is, one main distribution board may supply power via multiple branch circuits to several secondary distribution boards. Utilities may have some control over and access to the energy stored in electric vehicles attached to the grid. Many factories and businesses use these boxes to run things like motors, air compressors, and heaters. That is, a distribution electric box is arranged under the general distribution box, and a switch box is arranged under the switch box, and electrical equipment is arranged under the switch box to form a three-level distribution.
