How to Protect Critical Electrical Circuits?

Stringent safety codes require that critical electrical circuits are protected to ensure that power is maintained for emergency equipment in the event of a fire. Systems as:

  • Fire alarm & emergency lighting
  • Fire pumps
  • Emergency elevators
  • Smoke extraction fans
  • Backup generators

Typically require a 2 hour fire resistance rating. However, differences in national and local code requirements can be confusing. Next to the varying codes, building engineers have a multitude of options on how to design and construct such critical circuits. Learn about important recent fire and electrical code changes and findings – and the technologies at your disposal to meet them.

Protecting Critical Building Circuits from Fire

Whitepaper that lays out the evolution in fire safety codes and standards. Methods to protect critical electrical circuits are explained and compared.

Fire Resistance of Concrete for Electrical Conductors

Research report published by the NFPA on the thermal protection of concrete during a fire. A common method is to install conductors under 2 inches of concrete, but this does not guarantee a 2 hour fire rating.

Executive Summary

Proposed solutions for fire code compliant building design, based on the whitepaper and the NFPA report.
