However, those involved in the selection and installation of consumer units have expressed concerns over cable entries because these unavoidably penetrate the non combustible barrier of the enclosure. The concern being that a fire path could exist along the cables and through the cable entries to other combustible materials nearby.
To address these concerns Wylex has introduced its NMFS range of easy fit - self-adhesive intumescent strips to enhance fire safety in consumer units. Drop down seal
When the intumescent strip is exposed to sufficient heat a fire resistant “char” is created, this expands and flows around heat source filling the surrounding space and smothering fire by reducing the oxygen supply.
Once expanded, this highly insulating char also restricts the heat of any fire from reaching the surface of the enclosure, thus preventing fire propagation that may otherwise ignite surrounding materials.
Wylex worked in close liaison with one the UK's premier manufacturers of intumescents, and BM Trada one of the UK's foremost fire test authorities, using their expertise to assess the benefits of such practice.
