Is there an "easy" way of adding an earth/cpc terminal to a metal back box
that is already in position on a wall?

I have a situation where there is a single old, metal, back box with four
fixed lugs.

The space inside the back box is used to house connector blocks that join
two lengths of 2.5mm T&E. All this is covered with a blanking plate secured
with two metal screws.

The old metal back box has no cpc connection terminal. It is secured to the
wall with large nails where you would hope for screws (making replacing it
an unenviable job), but the metal is in good condition.

You could drill a hole in the side of the box and put in a nut and
bolt, or, especially if it's buried flush, drill the back and use a
self-tapper.

Drill through the side and put a bolt through.

Yes, as you say, thanks for the idea. If there is nothing special made for
this job,I was wondering about using one of the unused lugs; there is a
threaded hole there waiting to be used.

We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember "Anode" notvalid saying something
like:

Nothing to stop you doing that, if the lug isn't floating.

If you've got a pop riveter, fix a tail of CPC under a pop rivet with
washer.

Thank you all for the ideas, I'll look at the box in question and then
decide which method to go for.

Just run a CPC from the earth connector block to a blue crimp ring and
either use a pop rivet or a self-tapping machine screw with a washer to
fix the crimp ring to the back-box. If you're using a pop-rivet, you
might want to sandwich a star washer between the lug and the rivet to
make sure you get a tight connection.

Crimp an eye terminal on the end of a wire, and screw to the backbox
with one of these:

Looks more professional if you crimp a suitable sized lug to the cpc
then pop rivet the lug.

Extra crimps just mean possible extra problems.
