Sadly, yes it was quite a common practiceWhy do I keep finding this set up on installations over 20ish years old..was this the done thing back in the day??

Yes, very common. Not permitted now as all conductors must be within the enclosure.
Doesn't need to. However it must be painted green and yellow...So what sort of enclosure should conduit go in when it's used as a CPC?
Would hazard a guess that the joint box shown in the picture, is in my opinion far to small for the amount of cables that seem to be entering it 8 if my maths is up to scratch, should have used a plastic adaptable box, and as Wagos were to futuristic for the 70s a strip of connectors would do the trick nicely, cpcs as well.So what sort of enclosure should conduit go in when it's used as a CPC?
Must admit that is a poor job in the photo. Green sleeving was available back then. And a terminal block. Would like to see inside that JB, 8 t&e's I think it would only need a sprinkle of parmisano to finish it off nicely.
I did it at the bottom.cpc's should be wound on top of the JB and secured with a wire nut. then a bit of green tape to ID them.

Was never permitted.Yes, very common. Not permitted now as all conductors must be within the enclosure.
Hmmmm not sure I agree on that one. I think the general overall quality of electricians these days appears to be a lot lower than it was in the past.I don't think it was seen a bodge back then. Never done it myself mind. But in the 60s 70s when you were ripping out old, clamped conduit and lead cable that was used as the, then, earth and was totally exposed, then bare earth wire tightly wound must have seemed just as good or better.
Looks awful now though. Each generation of apprentice trained electricians improves on the last and so may it continue.
Reckon whoever did that mess want's shooting, crikey what a mess.all that needs is a couple of them american wire nuts. sorted.
it's a non-combustible joint box. what could possibly go wrong?Reckon whoever did that mess want's shooting, crikey what a mess.
Made for lead sheathed cables if my memory serve me well.Found this one the other day in a friend's roof. The cpc's of loop in/out are under the clamp at top right, the other 4 just twisted into that scruit externally. Might connect???View attachment 40226
maybe cheap but deffo not nice. how do the buggers get away with shyte like that?
Where's the strain relief on those cables!Neat Timbo- Never thought of using a surface box in that way - cheaper than a wiska and tough if a PVC box is used - will defo use that idea if the need arises!View attachment 40234
This is a lead sheathed lighting box, done properlyMade for lead sheathed cables if my memory serve me well.
It's just a JB in the loft!Where's the strain relief on those cables!
Terminate the cpcs in a Suitable JBReading this thread. what do people do with double insulated LED downlighters that do not have an earth connection in them? Lap from Screwfix do them, only bad comment is that.
When I think about it, a daft question. I am going to be replacing a surface mounted light in a kitchen and a bathroom. So i will just have 1 JB replacing the light accessible from the loft and the daisy chain 2 core flex to the three downlighter, using IP65 for the bathroom/wetroom. Should have thought more before posting.Terminate the cpcs in a Suitable JB
What about the earth being present at each point?When I think about it, a daft question. I am going to be replacing a surface mounted light in a kitchen and a bathroom. So i will just have 1 JB replacing the light accessible from the loft and the daisy chain 2 core flex to the three downlighter, using IP65 for the bathroom/wetroom. Should have thought more before posting.
Exactly except I will have 3 flexes into the JB as I am replacing one surface mounted light with three downlighter, or a daisy chain.The earth will be present at the junction box which is adjacent to the downlight. A short length of 2-core flex used to connect to the Class II downlight.
Same principle as the drop cable in a pendant.
