Plastering directly over T&E

[Guest55]

Doing insulations tests before final connections are made - is it worth while ?
Of course it bloody is.
bs 7671 testing guidance advises the testing is done during construction
The problem is most posters view scenarios purely from a domestic perspective.
During my stint doing highways power on motorways all cables are tested instantly after being pulled in because the cost of putting out a lane closure to sort out an unchecked problem costs thousands.
Same with large commercial projects - no point waiting till the jobs finished to do all the testing , theres just to much.

Ha ha ha, no I am most definitely not implying that you are a Electrical Trainee, that would be most inappropriate as I am not aware of your back ground. I was stating that this is the route I followed to enter the trade albeit working alongside a spark at the time.

Everyone has their own method, I am more than happy with mine and seems you are happy with yours. Whilst I can understand what others say about my method being a waste of time this is the way I work and it is because I am always looking to cover my arse and know 100% that all is sound because at the end of the day we are all human and humans make mistakes fact!

I understand also the point you make about time however the tests take next to no time at all and I have proof on my sheet that I can use should the occasion arise where a fault is discovered and the owner/ kitchen fitter/builder or whoever tries to pull a fast one:thumbsup

Cool, sorry about that, there are a couple of guys on here who regularly like to refer to me as a Electrical Trainee. Personally I have no issue with people who have taken this method of training and think that, with the neccesary experience, its perfectly suitable for people doing mainly domestic electrical work. Sorry if my posts come across a little aggresive at times. But seriously, its worthing thinking about which risks are worthing taking and which arn't. It can save you hours.

I've had two occasions where an RFC cable has been screwed by a kitchen fitter and both times I mangaged to locate the fault and replace the cable (via a different route) within an hour or so. No mess, no fuss, no units down. Theres always the last resort option of disconnecting the damaged leg of the ring (if its near the middle of the circuit) and creating 2 20 amp radials instead.

The problem with written text is you cannot judge the tone of voice being used in a conversation to evaluate which way of many that it is meant

As mentioned, you are happy. I am happy... together we are all happy I'm certainly not going to argue over it because it's only my name that goes on my certs and my reputation at stake. I am much less experienced than many on here I am sure which is why my method works for me too. Sometimes I get disturbed by clients or telephone calls which "Could" distract me so by testing at this stage I am able to address any fault that may arise due to whatever reason.

That oval conduit is better than capping. Ahem.

 

[Guitarist]

I always use oval conduit. Love the protection it offers, along with the fact that it allows for new cables if they ever get damaged.
Had a job a couple of months ago where a new socket was needed and when I checked, the nearest outlet was already a spur. Luckily there was conduit, so converted to part of the RFC.
I've lost count of the number of times I need to make alterations or carry out a rewire and say "thank you" when I find the whole place has conduit installed.

Btw, render affects the cable sheath, plaster doesn't.

I'm picking up a general consensus that cables don't need to be in capping or conduit...

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.

Additional protection to cables buried in thermally insulated walls buried less than 50mm from the surface needs to have "additional protection" by means of an RCD on the circuit. This is not an excuse for not putting oval conduit or capping on or over your cables. Both scenarios need to be met with basic protection by means of oval conduit or capping and then if it is in a thermally insulated wall (chased or dob and dabbed) that it be additionally protected with RCD.

You only get what you pay for, good spark = basic protection and additional protection (guy that has spent some time in school and on site), average joe spark = RCD the lot

Correct me please if im wrong...

 

[Swicade]

Agree with most of what you say there Ben Grant except:

'You only get what you pay for, good spark = basic protection and additional protection (guy that has spent some time in school and on site), average joe spark = RCD the lot'

As stated many (usualy the older hands) still use capping/conduit...it's how we where always taught BUT rules have now made it optional....doesn't make someone an average or bad sparks just because they dont do it the old way does it?

 

[SPARTYKUS]

As above Ben Grant I'm not sure you fully appreciate that the only reason capping is used is to protect cables from a plasterers trowel, where NEEDED !

My cables are usually covered in insulation

BS7671 Definitions.

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