Just fixed a ceiling light that had stopped working because one of the
earths had come out of the terminal inside the ceiling fitting.

Started me thinking, what if one of the wires had snapped off? There's only
just enough cabling to (just) reach the terminals inside the ceiling rose,
so what would the (sensible) option be? A chocolate block small enough to
fit inside the rose, or would you have to replace the whole cabling from
there to where it comes from?

Why are some sparkies so obsessed with leaving so little cable that it's
almost under tension when fitted? I put up a ceiling fan in my last house
and whatever wire I connected first, it left me with about an inch of gap to
put all the other wires in the right holes and screw up the fittings, while
balancing a heavy motor on my head. Ridiculous.

Hmm - does it rely on an earth to work?

You really need to have it checked over professionally if an earth coming
adrift stopped it working. Could be a very dangerous fault.

humbly suggest you rethink your faultfinding approach, and maybe take
another look.

Personally I would stick another JB in the ceiling, although you can
get small boxes containing a bit of barrier strip now.

An earth coming adrift won't stop a light from working unless it's
wired incorrectly. Wonder why an unexposed cable would come loose.

Probably because it was installed by one of Adam's ace apprentices?
That's what happened with our extension - on 3 separate light fittings.

I should have said that I tightened all of the wires up while I had it open
and the electricity off, I didn't think any of the others were noticably
loose but maybe one was, a couple of them (and the obviously misplaced earth
one) had been put into the fitting without (it looked to me) having had the
insulation stripped back properly first. I stripped them back a bit "just in
case" and refitted them nice and tightly.

If it makes any difference, it is a simple on/off switch that used to be a
metal dimmer switch and it controls 2 ceiling lights about 12 feet apart. No
idea why it stopped working when it did, it was OK one day and the next day
the lights were dead.

That's going back a bit. ;-)

Is this "earth sleeving" or "proper insulation" covering the earth cable?

On the earth cable was a loose-fitting green and yellow striped sleeve,
could be just pulled off with the fingers. It was this that was held by the
screw in the fitting, either the earth cable was never put in there or it
popped out at some point.

I have a bathroom light where the choc block is already wedged up to the ceiling with the wire ends just about poking out of the ceiling far enough to be caught by the terminals.

Some form of crimp might do if I could find crimp tool that will do 'end on' crimp instead of requiring sideways access to the cable.

I shall require similar if I am to repuropse the obsolete underfloor heating thermostat wires into 2 amp sockets for the 'tannoy' system. The wires have all been cut short in the BESA boxes.

It's so I can have classic FM in the bathroom.

There are a variety of PBXen for telephonically summoning the domestics.

Maybe they're different now, but I remember wondering at the time why they
didn't make the terminal block removable so you could wire it all up and
*then* plug the main motor unit into it instead of having to hold the whole
thing up with one hand and try to push wires into terminals and screw them
up with the other.
