About this file
This document is an electrical riser diagram and panel schedule for a commercial facility electrical upgrade project. The design shows the integration of an existing 350 kW, 437.5 kVA emergency standby generator (120/208V, three-phase) with new electrical distribution infrastructure. The system includes a new 600-amp panelboard (Panel APH Section 2) fed from an existing 1200-amp bypass switch, with a 1.9% voltage drop from the service entrance to the new panel. The existing service entrance maintains a 1200-amp main disconnect rated at 208V, three-phase, four-wire, NEMA 3R with 2000 AIC rating. The available fault current at the service entrance is 17,409.139 amps, while the available fault current at the new panel disconnect is 44,297.238 amps.
Panel APH Section 2 is a Square D NQOD cabinet with 600-amp main lugs only (MLO) or 600-amp main circuit breaker (MCB), rated 208Y/120V, three-phase, four-wire, with a total panelboard load of 106.1 kVA across three phases. The schedule details branch circuit designations for work stations, printers, and office spaces distributed across three phases, with individual 20-amp and 30-amp breakers feeding various office areas (123-128). Integrated equipment ratings are 22 kAIC. The project notes specify that all new circuit breakers must match the manufacturer and AIC rating of the panel, the existing 1200-amp generator circuit breaker must be verified as 100% rated (or replaced), and a new 600-amp trip circuit breaker must be installed in the existing bypass switch. Grounding includes #2/0 copper conductors to a driven ground rod, cold water pipe, and building steel per NEC 250 standards.
