Hi all
Where a cable is secured to a ceiling with non fireproof fixings but above a metal grid suspended ceiling and in a communal escape route would this be in breach of 521.10.202? The cable is not resting on the ceiling grid but fixed to the concrete ceiling above it with plastic ties and blocks. Note 3 of 521.10.202 implies this only applies to cables "clipped direct to exposed surfaces". I have no idea if such a suspended ceiling (5 years old) has any fire resistance at all btw.
