Earths twisted up outside of joint boxes.

Why 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.

Sadly, yes it was quite a common practice

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.

Doesn't need to. However it must be painted green and yellow...

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.

Yes this was a common practice, I did it because it freed up a terminal inside the JB. (tin hat on)

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.

I did it at the bottom.

Once fitted conduit in a posh factory where we had to work like mad as the painters were only about 20 foot behind us covering everything in orange paint.
(Regulation colour for electric (silver for steam pipes) then, is it still? )
