About this detail

An electrical distribution diagram details the interconnection of power panels, transformers, and meters including surge protective devices. The system incorporates multiple distribution panels such as HP-4E-1 rated at 200 A main circuit breaker with 480 V, three-phase, 4-wire, 42-circuit capacity, and HP-2E-1 rated at 100 A main circuit breaker with 208 V, three-phase, 4-wire, 42-circuit capacity. Step-down transformers like HTX-4E-1 provide 30 kVA capacity converting 480V to 208/120V. Four-pole switches including HATS-E-1 and HATS-OS-1 manage specific feeds alongside emergency generator start control signals and ancillary power connections.
