Lo scenario
Industrial facility requires continuous control power even during utility outages; a 480V distribution panel supplies six motor loads while a standby generator and UPS support critical control circuits.
Cosa contiene questo disegno
Leggi le decisioni che ne stanno alla base.
01
Utility and generator sources are combined through an automatic transfer switch feeding the main 480V bus
02
A dedicated UPS input breaker feeds a 40 kVA UPS that powers a separate 120V control bus
03
Each motor feeder is protected by an individual breaker sized to the motor rating
Use for industrial single-line diagrams where control power must remain available during generator transfer or utility interruption, and where multiple motor loads are served from a common distribution panel.
