Fire resistant cables 

on safety equipment

Don't let a supply cable be the cause of failure

Safety equipment must be configured to allow building occupants time to escape.  Cables providing electrical power must guarantee they function under extreme temperatures.

Use the appropriate cable 

sizing calculation method

Cable sizing for fire conditions is different from normal operating conditions because electrical resistance increases sharply as temperature rises. This means a correction factor must be introduced.

The aim of this campaign is to rise the attention of Electrical Professional on the appropriate sizing of Fire Resistant cables.

The simplified procedure explained in the document doesn’t replace local installation standards.
