Fixing of trunking/wall mounted isolation switches

[stratplus]

Hi all, when fixing the above into plasterboard do you ever use raw plugs or do you always use plasterboard fixings?

Always plasterboard fixings, or screw straight into joists/battens.

if at all possible I screw a sheet of ply to the studs before the plaster boards go on. Saves a lot of work later

Always platerboard fixings, or screw straight into joists/battens.

Always used to use toggles for anything on the heavy side. Never had any of those fail on me...lol!!

Red wall plugs are a no-no, they seem to work, but soon fall out or end up going round and round when you screw the screw in. You can get away with the metal 'thorsman' (other-makes-may-be-available) screw in jobbies for static loads, such as the trunking, unless its 50x50 full to the brim. As Eng54 says, toggles are better, especially for isolators which will have monkeys dangling off them every so often.

The only things plasterboard is good for, is ceilings and filling skips.
This is the stuff for walls...

All I ever use now.

a silly question in a way, who would use raw plugs in plasterboard?? I actually agree with spinlondon and do the same.

 

[dim_bulb]

just screws and decorators caulk then walk away.....

stickyback with a few clip nails for back-up. :24:

I always use wall anchors but noticed a spark using red plugs and screws!!! I questioned him, said he's always done it. I put a screw driver on one of the screw expecting it to spin but it was tight as! Hence my question on here.

when you drill 5.5mm and use a red plug it goes in nice and tight. does the job with self adhesive trunking, when fixing isolator or a socket better use plasterboard plugs or try screw it to a batten underneath.

I'm not a fan of redi-drivers tbh especially on pipe clips.

 

[stratplus]

It seems the majority of sparks I speak to in the field use red plugs when fixing trunking and light items to plasterboard! Hmmm not such a daft question it seems.

Ive never met one who uses plugs on plasterboard yet myself

Allways fin the studs/ tins if possible and use the 600 rule to screw it

Anything thats not going to get abuse/quite light, red plugs and screws. If done properly, their absolutly fine. Otherwise metal plasterboard fixs or better stilla noggin.

I'm a big fan of Sikaflex which is basically an adhesive. We use it on trunking along with a few screws. The majority of our installations are data cabling but I'm sure it would also work for smaller power cabling as well. It works even better if you fit your trunking at least a day before you put the cabling in.

Tbh redi drivers aren't that great. They pull out just as easy as red plugs.

 

[stratplus]

Personally I'd use plasterboard fixings but I can see both sides of the coin.

 

[stratplus]

I don't think raw plugs are classed plasterboard fixings. Would be a wrong answer on a c+g paper!!!

 

[Mitch6278]

plasterboard fixings or try using intersets..very strong if its double skin plasterboard!!

The thing with BS7671, is there is quite a bit about good workmanship, taking note of manufacturer's instructions, choosing suitable equipment for the conditions even ensuring that an item meets the appropriate British Standards for the use that item is being put to.
As far as I'm aware rawl plugs are designed to be used in masonary, not to be used in plasterboard.
It may be that using Rawlplugs in plasterboard would not comply with BS7671.

 

[stratplus]

Very true

 

[tigerpaul]

I'd never use standard rawlplugs on plasterboard. And I have never met a spark who would.
Screwing into the batten is best but if you have to go into the plasterboard then Twirly plasterboard fixings are okay, but the best fixings I find are the brolly type.

 

[jumpin jax]

Aren't the rawl plug uno designed for plasterboard? Those are the rawl plug with the lip to stop them going in to far.

It would appear that they are.

Ooh nice!
