FIRE RATED DOWNLIGHTS AND PLASTIC CCU - WHAT SIDE OF THE FENCE?

[NICKYNUNN]

1. This does not directly reference whether or not the lights themselves are fire rated. (As has been mentioned by @Pretty Mouth , some open back downlights are fire rated)

2. The bit about "the room above" only applies if the room above constitutes a separate fire compartment, which the book fails to point out.

The problem with the Codebreakers book is that it is only a compilation of opinions, with no real explanations given, and mostly vague references to regulations. It can be useful, but like any such opinions, needs to be taken as advice only, and not rigid rules.

(And yes, I do own a copy and have read it through from cover to cover, making notes of my disagreements and actual errors found)

Thanks ?

Thanks ?

Your welcome. Hope it helps.

The more these questions are asked, the more opportunity there is to shed more "light" on the answers, such answers (usually) being only available through both thorough research, and the experience of the members of this forum.

Edit: and of course John Ward! (And others on YouTube)

Definitely ?

The purpose of a fire rated downlight is solely to maintain the integrity of the fire barrier that has been penetrated by the insertion of the said light fitting,l

This is why it doesn't get a code, but I use my judgement as an engineer concerning the possibility of flammable materials collecting on the upper side, and give a strong recommendation for them to be replaced with can types in the notes accompanying an EICR.

9 out of 10 sparks Ive spoken to say C2 for non fire rated downlights and C3 for plastic board.
I'm pleased I asked on here, I appreciate all the advice.

Are the 9 just blindly following the advice books or are they using their knowledge and experience or lack of it to come to the decisions they have made
I might be wrong but in some of your posts you seem to be fixed on what code because it needs a code, or is their a need to code something to satisfy yourself or your client that your ECIR is credible
None of the advice books can clearly define beyond doubt each and every circumstance perfectly and obviously for that reason there are some elements that need local on the ground input to justify the coding that the books offer while BS7671 is the primary reading this has to be read in conjunction with the building regs and any other documents that affect the use or construction of the property

As has been demonstrated in this thread the decision on some coding needs a little bit more than just electrical knowledge to make the coding decision, if the plastic CU is in a firelined cupboard would it necessarily need a code
