Cable clips as per 18th edition.

ZippyMo · Apr 16, 2019

Friends,

I'm rewiring my brothers house tomorrow. Can someone tell me if the new 18th edition allows me to use the plastic cable clips to secure the cables to joists etc?
Or do I have to replace them with metal ones?

Thanks

Is the joist above a plaster board? If so then the plaster board is a fire barrier so plastic clips can be used.
Tin hat on....

Are the cables above plasterboard?

No tin hat, plasterboard is rated at 30 minutes. After 30 minutes of fire would collapse be classed as premature?

What if the fire brigade arrives within 30 mins?

Have a look at this.

I'm presuming that this is a worst case scenario, with all the doors open.

If it’s above plasterboard, don’t use any clips at all.
That way you don’t have to worry whether the clips comply.

I was watching a vid about subject, as well as other matters, hosted by IET. Napit bod tried the argument that cable above plasterboard ceiling needed metal clips. Everyone else in the room surprisingly didn’t agree. I wondered what he would suggest doing during rewire or alterations; get a very small apprentice.

What was his reasoning behind this?

Probably some paper pushing bureaucrat who has no clue about what he is talking about, like a lot of the Cretins that make up the Scam's rules, technocrats most of them, no practical experience whatsoever.

Congratulate them for getting there quickly.

At school I'm sick of retrospectively tidying cables up from past lazy contractors. The amount of times I go and do a job only to see a stack of cables draped across the false ceiling after I lift a tile up. I use metal cable ties, probably overkill because many would argue the metal grid of the ceiling would act as a support, and if that comes down then it's game over, but I'm not sure I could live with myself if somebody lost their life because I tried to scrimp a bit on some clips/ties.

It’s not just the weight of the cables on the grid thats a problem, they shouldn’t be installed on the grid for numerous other reasons.. mainly due to the sharp edges that can cause damage to the cables
