Sequence Flow (Normal or Uncontrolled)
A sequence flow is used to show the order in which activities in a process or choreography will be performed.[1] Symbol 1] Silver, B. (2009). BPMN Method and Style: A
Adiabatic
Adiabatic checks are required to determine whether conductorsmight be damaged by the thermal effects resulting from the level of calculated fault conditions.
built asset

coordination
Coordination goes beyond orderly task execution, it transforms individual perspectives into shared, community-wide actions. It’s not just a subset of collaboration; it’s the engine that makes collaboration more than a patchwork of solo efforts.
Harmonic rating factor (Ch)
Ch Rating factor used for calculating theminimum required cable size in the presence of harmonic currents.See BS7671:2018,Appendix 4, section 5.5.

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.
