Cable Selection for Fire Protection Distribution Boxes

Home / Cable Selection for Fire Protection Distribution Boxes

Standard BS 8519 is a designated code of practice for the selection and installation of fire-resistant power and control cable systems for life safety, fire-fighting and other critical applications. FIRES BREAK OUT IN EUROPE EVERY YEAR FIRES ARE CAUSED BY ELECTRICAL FAILURES (SOURCE FEEDS) COSTS RELATED TO FIRE SAFETY To mitigate the risks, each country has developed its own regulation regarding potential hazards in sensitive buildings like public buildings (hotel, cinema, theatre, schools. Originally published in 2005 under BS7346-6 standard, it was withdrawn and superseded by BS8519 in. If you are responsible for specifying, inspecting or regulating fire resistant cables for large or complex buildings then you need to be aware that the standard BS 8519 has been fully revised. Martin Boorman from Prysmian outlines some of the major changes to the guidance on selection and.
