Secondary Supply – diverse cable route

This guidance covers the routing of secondary supply cables from a life safety generator to the ATS (Automatic Transfer Switch), and the final equipment with reference to:

BS 7671:2018+A2:2022, specifically Section 560: Safety Services

BS 8519:2020, with emphasis on Clause 7 (Cable Routing) and Clause 11 (Cable Selection)

The goal: clarify requirements for the diverse cable routing and maintain circuit integrity under fire conditions for systems that support life safety and fire-fighting applications, such as sprinkler pumps, fire-fighting lifts, and smoke control systems.
