well if your consumer is mounted on timber and many are dave, if your cables are entrering back entry kind of defeats the non combustable method to me

Its not in the book but it has been noted that Good workmanship and proper materials must be applied by the installer. The cable installation entry method shall, as far as is reasonably practicable, maintain the fire containment of the enclosure. Account shall be taken of the manufacturers instructions, if any.
IMO if one of these boards are mounted on a plaster board wall with the cables entering rear entry I don't see no harm in sealing the hole with a bit of pyro mate or the like "as far as reasonably practical" to maintain the fire containment of the enclosure.
[h=1]FLUE JOINTING COMPOUND[/h] |
A non-setting, weather resistant, non-flammable, stiff putty material which allows small movements without breaking the seal. Recommended where pipes and flues emerge through concrete, stone or brickwork; and for both external and internal flue pipe joints. FJC can also be used for sealing service pipes and conduits of all types through fire-rated walls. May be used for sealing the gap between a gas pipe and the sleeve through which it passes. Must not be used either where the pipe will be hotter than 250°C (482°F), or directly onto heating appliances. Manufactured in the UK by a BS EN ISO 9001:2008 registered company.
