Where are you getting your metal buckle clips

[haptism]

Only place i can think of is in a garage, don't think I've ever just clipped a cable across someones living room wall.

If we are running surface cabling then its usually mini trunking and those D-Line clips.

How about a 5m run along a single joist (without going through the joist itself) in a loft with lathe ceiling below, what about that !

Lathe I hardly ever see that stuff anymore. I'd not really thought about it but I guess the fire rating is pretty bad.

Would it still be considered 'premature collapse of the wiring system' if the ceiling below has already collapsed? Obviously fitting a metallic clip is going to be best practice, you can't really go wrong then but it makes me wonder where to draw the line at 'premature collapse'.

Edit: D-Line advertise their clips being used outside of trunking also so I guess thats an option. Idk what the price of them is like, I'm on the books so just book them out at wholesaler

If the fabric of the building has collapsed then the collapse of the wiring system could hardly be described as premature.

Good point Andy, can I ask where you would consider installing metal buckle clips or similar in domestic ?

Other than clipped direct at high level in a loft; or along a hall, or over a door (which would likely be in trunking anyhow, utilising metal u-clips), I cant think of any other scenarios.

Like you say, up high in a loft might be a good idea, and across a joist in a garage, but otherwise not many cases in domestic work where I would clip direct where the cable would not be supported by the building fabric.

Externally prehaps? Cables/conduit above doorways could be liable to collapse and block the escape path

Just finished some work in my bosses new house lots of cabling put in loft space and no fire rated fixings employed.

Suppose you could argue that if the fire was in the loft to melt the clips then the ceiling would have already failed

I feel it is a pointless exercise.

The entire regulation and its intention, or just the situation you were on about ?

 

[Wilko]

If the loft is not a habitable space I guess cabling, if it were to fall, is falling onto the ceiling ...

Just the situation in the loft space.

Yes I believe so,or proper metal containment,where appropriate.
Let’s go back,go back,when we were all installing correctly & proper,conduit,trunking etc .

Yes if anybody knows how to do it in these days.? lol

If you are clipping in a loft space, let's look at the situation where we have cables clipped to boards that span the rafters. The usual clips are fine to be hammered in where the support boards are on or very close to the main timbers...hammering halfway betyween the main timbers is hopeless due to the bounce, unless you can get someone to hold a big hammer behind...so, you use buckle clips, substituting small screws for the nails. That way, you can drive the screws in midway, through the clips, and just fold the buckle over the cable...if that makes sense.

I've undertaken a couple of domestic re-wires this year and decided to go the whole hog on the fire rated clips, to see the impact on cost and time. To clarify, I used F-Line clips from D-Line. These allow 3/4 cables side by side. Used them every 400mm or where practice. Only used them when traversing ceilings or the loft and I hadn't gone through the joists. Quite time consuming to keep changing from hammer to impact driver when swapping from plastic clip to metal strap. Factor in a couple of boxes of 10x1.5 screws and the overall costs aren't a deal breaker at an additional £30 or so. It's the additional time spent and the ball ache of dragging the impact, screws, 2 lots of clips and the hammer around with you in confined areas. Looking at the metal clips from SF, I reckon £12 for 100 isn't too bad.
