Summary of Three-Tier Power Distribution System: Primary: The main distribution panel, supplies power from the transformer. Secondary: Intermediate panel, routes power to buildings or zones. Tertiary:
Distribution Boxes shall have Isolator (Switch Disconnector) on incoming circuit and Porcelain CUTOUT fuse base disconnector on outgoing circuits with necessary interconnecting Bus Bars.
As for the equipment inside, there are certain differences: the first level distribution cabinet generally has isolation switches, circuit breakers, leakage protectors, etc., the second level
Three level protection refers to: on-site construction of electricity must be done in the general distribution box, distribution box and switch box to install leakage protection.
