25mm PVC Channel

[pauldreed]

I'm using lengths of 25mm PVC channel to bury some cables in plaster/breeze, but despite trying several nail sizes, the channel keeps splitting & cracking when I secure it.
What nails are recommended to avoid this please.

Ah - so we're assuming that it's cable in a channel, rather than on a blank wall??? See, makes a difference, doesn't it.

But when spreading the muck on the wall the trowel is naturally held at such an angle as to not do damage to cables, or maybe that's just me...

Also, assumption, the mother of all???

I was assuming chase
If its in a chase I don't bother with capping, the chances of the plasterer slicing a cable is almost nil. Unless you've peed him off, then he might just to annoy you.

Your more likely to damage the cable trying to hit the caping nail in, than the plasterer...

But if you have to then do it properly and use these felt nails the heads are huge

Which is cheaper: a few pence for a length of capping and some nails plus a couple of minutes, or having to dig out a damaged cable when you come to test it and find it fails it's IR? For me, it's a no-brainer.

Steel capping, sharp edges doubled over. Clout nails at the side of the capping. if the mortar is crap a 5.5mm hole drilled into the brick or what-have-you with 3 or 4 clout nails crammed in! Job done!

I completely agree mate.

I clip direct then put bonding coat on myself costs less and plasterer happy too, do it all at end of job only takes minutes.

 

[telectrix]

nails out of T/E cable clips do the job without splitting the capping. or, as previously suggested clout nails but alongside, not through the capping. the heads hold the capping in.

 

[ezzzekiel]

Usually plasters too thin for capping or oval and chasing out deeper channel into brick is no easy task, yet to find any damage bad enough to cause trouble due to a plasterers trowel.

If its a soft block use corse threaded plasterboard screws. Don't worry about drill and plugging it just screw em straight into the blockwork. Works a treat

You won't have any problems if you use metal capping instead of plastic.

 

[macca_31]

who doesn't use capping ?? surely its benificial for everyone !!

 

[Swicade]

I've always used Galv capping ....hate pvc capping due to it twisting while trying to install and the cracking when trying to nail it.

Maybe i'm alittle too oldskool here but i was under the impression Capping or conduit had to be fitted for mechanical protection (what little protection capping offer's) of the cables......maybe thats just me being taught old ways though back in the day and sticking to it.

Capping is fitted for protection of cable from

The plasterers trowel

The pests chewing on cable

can allow cable replacement(sometimes)

from chemical affects of plaster/insulation.



Capping does not afford protection from

Drill bits

Nails

Screws

Hammers.

plaster board nails clouts what ever you want to call them or a splodge of dry lining adhesive always does the trick

Personally, I always use oval conduit and pin it either side with galv nails. I can then take cable through insulation in a loft to avoid the 100 club, as well as it being there to help the next rewire... Oh, and it's good protection when a messy plasterer turns up.
