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!

Ben, as Dillb says, capping has nothing to do with "basic protection". I think you are misunderstanding the meaning altogether.

May I say I don't like cables being in the wall without "basic protection" yes there is a tick box on the schedule of items inspected on both an Electrical installation certificate and an electrical installation condition report to say that the " basic protection" has been met.

I think you may have been ticking that box without understanding BS7671's definition of basic protection!

BS7671 Definitions.

Basic protection= Protection against electric shock under fault-free conditions. So capping has nothing to do with this what so ever.

So basic protection is the cable insulation?

It doesn't even need to be double insulated, that means singles clipped to a wall, no capping and plastered is O.K.

Yes but it is for all insulation on the circuit form the cable insulation to enclosures to socket fronts etc. In laymans terms no live parts can be accessed anywhere on the circuit if there is no fault on it.

capping is not considered as additional protection....its there purely to stop plasterers (rough gits) from cutting into our cables with their trowels...

Put capping in don't put capping in. All the pictures on google I have seen have been with capping/conduit. Don't wanna put it in... Then don't, I get a better sense of pride when it's there, separates the men from the boys

well if the walls are to be dry-lined then PVC/metal channel isn`t really necessary is it....you look at the job in hand first to assess what needs doing....then go with that....its the same for most things isn`t it....

So .... to sum up for the OP. "If the cap fits..."

All I can reiterate is "Thank god for the electricians who used oval conduit 30 years ago". Saves me a world of pain when I start on a rewire

well this is it....having the foresight to see that the install they did had a finite lifespan.....
