Designing a hospital emergency power distribution system requiring seamless transfer between utility and a 2 MW diesel generator using a closed transition automatic transfer switch.
What is in this drawing
Read the decisions behind it.
01
Selecting a closed transition ATS to avoid power interruption during transfer tests and short outages.
02
Using a 2 MW diesel generator rated for the hospital's life safety, critical, and equipment branches.
03
Incorporating separate breakers for each load branch to meet NFPA 70 and NEC 700/701/702 requirements.
Use this template for hospital or critical facility emergency power single-line diagrams where a closed transition ATS coordinates utility and generator sources.
