Had a proper look at the earthing on the new place today. The supply earth is provided by a clamp onto the sheath. It's not, so far as I can, a tightenable clamp.

It has a 10mm cable in which looks like it only just fits, can't see how I'd get a 16 in there. (tails are - at the moment - 25mm as far as a Henley, then down to 16mm)

I noticed that the clamp rotates freely around the sheath. Is that to be expected? I will get round to measuring the earth soon when the replacement test lead turns up.



FWLIW I think I'd ask if a "proper" PME can be supplied

I was considering that. Assuming the clamp isn't expected to move as it does (??) I was going to call up and express concern about it, and see if that ended up with a PME conversion.

I was leaving the clamp to my youngers and betters But FWIW (a) a
clamp that moves patently means your Ze can change randomly, (b) clamps
(even constant force clamps) on lead sheathing are now a no-no, and (c)
I think tightening a clamp is for the brave and courageous.
