Plastering directly over T&E

[tedglen2]

Hello all.

I have goggled filling T&E with plaster and there are a lot of responses saying plaster will corrode the cable?

Is this just a myth? Will I be ok to just clip the cables then plaster over myself!

Ted, if you are ready to plaster than I am presuming that all the cables are in? This would be an ideal time to get the first fix tested for continuity and an insulation resistance test carried out.

This is where wago connectors work a treat:thumbsup

not ready for testing, just thinking ahead really !!!

Inspection and testing should be carried out before, during and on completion of works. It saves getting to completion and finding a fault. It is possible to find faults on new cable or for unknown mishaps to occur during installation. If you're thinking plaster and the first fix is not complete then it sounds like you may be jumping the gun

yep i am jumping the gun. i always worry about future problems !!!

Long ago in days of yore it was recommended that cables be capped. The Electricity Board inspector was liable to take an accessory off and see if the cables were loose (capped) or fixed (plastered) and I am told would refuse to connect if not capped (mine were always capped so never found out if this was true). I am told the cable sheath is now resistant to plaster and that used not be the case with the original PVC sheath. So bury in plaster, but I still prefer to cap them even in a chase.

Being prepared is one thing but giving your attention to other areas of concern whilst carrying out electrical installation will catch you out. Electrics is all about working methodically so once you have proven continuity and IR THEN you can think about plaster. If you are going to cap cables then the testing will need to occur after this because it is possible to nip a cable in the process. If plastering direct then you will still need to use cable clips on the cable to secure them to the wall. If you do not do this then the cables will keep bouncing off the wall and probably end up being visible after you have plastered.

One thing I would add is, get that ****ing sparky in to help/advise you appropriately. Regardless of what you are paying him for his services he will be responsible for the entire installation of the circuit/s if he is signing it off!

The main reason for capping is to protect the cables from mechanical damage during the process of plastering....not from the plaster itself.

Testing before 2nd fix eh? That's a new one. Total and utter waste of time IMO

So now we know who tedglen really is. Do you honestly think you should be helping sparkies out at 92 years old Phil?
Put your feet up man just like you've done since the end of the war

 

[tedglen2]

lol - I have a lot of chasing to do

 

[trev]

Aye, after all the minions and anything in a skirt if the old reports are true you old dog
