earth cables with no sleeving

I was replacing a socket for my folks and noticed a bunch of sockets that have earth wires that are not sleeved. I didn't have any sleeving available at the time.

Does this present any major risks and how urgent is this sleeving?

Thanks in advance.

Bare earth conductors may get pressed against bits of bare metal and/or copper that is either Live or Neutral when the faceplate is screwed back in place.
 
Are they bare copper or bare tinned (silver colour) copper?

If the second then it could be very old wiring . . .

There would be a (probably small) bang and an MCB and/or RCD would trip (immediately one re-energised circuit after replacing the faceplate). Nothing too dramatic.

The benefit would be that you then have an opportunity to pay another visit to your folks! LOL.
Honestly, you seem to be doing a heap of electrical work.
Earth sleeving is a cheap and basic thing to have in your tool bag.

I'm not totally sure what you are suggesting, but I do not see any significant risk/danger (to persons) that would arise from the 'bang' behind an accessory, after one had re-attached the faceplate (hopefully whilst the circuit was dead) when one re-endergised the circuit, almost certainly at a location distant from the place where the bang was going to occur.

Indeed. Was it not apparent that I was merely answering the "what would happen?" question, NOT talking about what I personally do (which, for what it's worth, is to always use sleeving, even though I doubt that history would be different if I never had done so :) ).

Alright, here goes:

I have often wondered why we sleeve the CPC. It is true that it might be squashed against the Line terminal causing an earth fault or the Neutral terminal causing earth leakage current (unnoticed without an RCD) but that would surely be careless installation. So - with careful installation what difference does sleeving make apart from facilitating sloppy squashing of wires together?

Would it not be better to have more earthed parts with which a stray Line conductor could come into contact?

Is sleeving mentioned in the regulations other than possibly 'identifying' the conductor (if that were ever needed).

Why are back boxes not insulated?

Same here. As I'm said, I've always done it - but, as I have implied, only because I wanted to avoid being criticised for not doing it!

Agreed. Except in situations when appreciable movement/vibration is likely (e.g. in vehicles or 'machines'), I see no 'purpose' other than what you mention

That could be argued.

I may be wrong, but I can't think of anything in the regs which requires any CPC to be sleeved, beyond, as you say, the requirement for identification (which can be satisfied by the smallest bit of G/Y).

It could happen, but the design of the socket makes it very unlikely, all L/N parts are recessed (IP2X??) on the sockets I've fitted
