Requirement of gaskets for BESA or universal box.

Mirak

Please help me to get clarification on the below statement. Is it a requirement according to the BS7671 and Buiding Regs? 

"Where conduits pass through fire-rated ceilings and walls, it is a requirement to terminate each side with a BESA or universal box fitted with intumescent gaskets to stop fire penetrating. It is also a requirement to fit intumescent gaskets in the back of metal switch/socket boxes where they are back-to-back and cables pass through the wall."

    That exact form or words is not BS7671. However the sentiment, of preserving the fire integrity when drilling holes in a fire wall /ceiling is certainly.important and intumescents are one way to do this.

    The wording is from the manufacturer's guide. Thank you, Mike.
