While looking over a PIR for a domestic flat, the approved electrician has entered for the Cooker circuit a cable size of 10sqmm but has scored thro this and entered 8sqmm. For the shower circuit he has entered a cable size of 8sqmm (no score out). So he must have intended a size of 8sqmm, but...
All comments are perfectly valid. If you want to be sure, get the lot rewired. If not, forget any scare mongering over the small asbestos flash pad. Since Grenfell and after a fire prevention visit, my wife now closes the kitchen door before retiring upstairs to bed. Danger is all around...
Den,
I would advise you to get the EICR done first. If your existing c/u is non-compliant with BS7671, the EICR will detail this. I believe that an EICR should be done after a new C/U is fitted any way.
Cheers

The reason I ask is that my next door neighbour has a lighting fault whereby the line to the one-way switch is "dead". The house has fitted carpet. To find the break, it would mean lifting the carpet! This made me think of all the jobs I've done and seen done whereby joint boxes are below a...
I was thinking of a pre-existing screwed type. It was common practice at one time to use Ashley screw down terminal joint boxes sited below floors. Do I take it that this practice does not comply?
A spark will soon suss out whether you've lost the feed or the neutral to those lights that are not working. The loss of either has to be either a break at a connection at a three terminal ceiling rose, or behind a switch or in an octopus joint box below the floor.
The thing is, it has taken more than six years to show so forget that. If it had. Een a mere month or two ago, I would have got the fitter back. Even the system installers were subbies of the Brittish Gas.
I will repair the fault myself but am only showing what can happen in the life of an...
All joking apart, and based on practicalities, as what happened to me was my downstairs lights all failed one night. I checked all connections at the Consumer Unit and found them all to be tight. I removed two wall switches and saw that there must be a joint box or three terminal ceiling...
You are right, Ian.
Was thinking of the type of terrace house where the octopus system has been used with the large joing box below the upstairs floor and client has composite flooring fitted. This would be a nighmare to gain access to the joint box. As you say, there is no right way.
Alternatively if we all in future use the switch boxes as the joint box, then no joint boxes are necessary, even with down-lighters. The point is, joint boxes, if unable to be left easily accessible, then don't use them at all. The switch box method also makes inspection and testing easier and...
Thanks, guys, for all your replies.
Not one of you has said anything that I don't agree with. We often do things without thinking why. I try to think of myself or A.N.Other, coming back to the installation for maintenance, or replacement.
Thanks, Murdoch. Why did they get away with inaccessible joints. Is it the electrical Foreman to blame or what, speaking generally. I mean I've done this myself but never without a drawing and an indication of the removable floor hatch.
To my knowledge, there are 3 methods of splitting the line conductor in each lighting circuit:
Joint box below floor, or above ceiling
Three terminal ceiling rose/batten lampholder
Joint in switch box (neutral)
I am wondering which method is most commonly used in new houses.
I have been in...
