Typo. It's not an exposed-c-p.
Need to earth back boxes? Earth sleeves etc.

Well, to be fair, it's not either sort of "e-c-p" (unless the plaster/wall is very wet all the way down to the ground!). However, as you imply, it's probably not what TTC intended to type!Typo. It's not an exposed-c-p.

Ahh whoops 
Neutral is a live conductor.
Then so is the CPC a Live conductor, or do the electrons change uniforms when they cross the border between Neutral tails and CPC in the cutout ?
No it isn't. It is a protective conductor as it is not intended to carry current during normal operation.
Are you getting confused? can't keep up? the purpose of the link was to show waffleman that plastic boxes have earth terminals, it's the little brass thing in the corner.
Some do, and some dont't. ... and, in any event, plastic ones such as you kindly linked to obviously do not need earthing, via faceplate screws or anything else!
However, you don't seem to be very good at reading. What I wrote was that plastic light switches do not usually have earth terminals (and certainly not ones which connect to the faceplate screws) so, with such an accessory, the faceplate screws cannot earth a (metal) back box to which they are attached (in the way that a metal light switch would).

For the OP, just earth the metal ones with a short link of insulated\sleeved cable, its simple to do so you may as well do it.
The rest is just the sparkies bitching over semantics and those horrid and unsafe screwdrivers.
P.S. Use 20mm gromits when coming through the knockouts on all metal enclosures.

Let's see. John said "Be aware that the same is not usually true of plastic switches (like light switches), since they have no earth connection, so cannot earth a back box via faceplate screws".
And you then called it nonsense, and posted a link to a plastic box, which even though it has an earth terminal also has no connection to the screws.
You aren't very good at this, are you....
That might be a factor contributing to your desperate incompetence.
If you CBA to read posts, then do the decent thing and likewise CBA to reply.
You can do decency, can you? Or is that something else you aren't very good at?

Don't get why the attitude watson? Surely life is easier when we all collaborate. Seems you are very bitter about life and want others to fail. Are you like Risteard and think this forum is a closed book only to be opened when it suits you? What's the point of you being here? I come here to learn. Attention seeking maybe ?
Quite so. He's not the only one, but it does rather look as if he may have a very troubled life, and his posts suggest that his participation in this forum could well be making that worse for him.
He is also making a complete fool of himself, but maybe he's too tied up with other problems to worry about that.

Gawd...anyway, sockets now wired in to back boxes, with back boxes earthed as standard but still a stand alone dead circuit.
Now, how to connect it in to mains supply?

The two short tails protruding thru the beam over the door (with longer tails from new circuit/sockets hanging down) are the same two with red tape on their ends under the floor amongst the rest of the services. They mean that I don't need to drill holes thru 2 joists and 2 skins of brickwork to connect the new to the existing.
