Our supplier has been chasing us for ages to have one, so I just tried to book to have it fitted. I was told it couldn't go in an outside box.

Ah ha!!  That solves my problem then.  My meters are both in an outside box, with only a thin plastic door between the internals and the howling westerlies, bearing driving rain up the eastern slope of the Dee valley, which on a wet and windy winter's night saturates that wall of the house and lifts the roof tiles as we lie in bed, listening to the gale. Good job that both meters boxes are sheltered behind a 30 yo laurel bush then.

Many houses have outside meter boxes, that's so that the meter readers can get to them.  Is this more incompetence from the smart-meter promulgating fascists?

Does anyone know *why* the meters can't go in an outside box?  It's not like a traditional meter is particularly waterproof, so I doubt it's that.

It said something about low-profile meters and outside boxes. Didn't make a great deal of sense to me. I'm not necessarily saying that no such meter will fit any outside box, just that that's what our supplier said when I tried to book.

Not fitting in a standard meter box sounds entirely typical of the level of standardisation we've come to expect from the smart metering fiasco...   >:(

They cancelled my first appointment because I’m dual fuel with my supplier and the meter installer didn’t know that.

I told the installer that the gas meter was outside and the door was broken. He still made he appointment. (That one got broken too, and I got £30 for it).

Our electricity meter is a smart one and in an outside box.

A Youtube video of BigClive taking one to bits.  Answers a lot of questions, I don't know which type though.

I've not watched the whole thing but...
That thing he called a relay for disconnecting you.

Is it?
I couldn't make out the writing on it.

Is it not more likely to be a Current Transformer which does the metering?
I don't see any other metering device in-line with the main terminals.

Switch on the 250VAC line
Magnet on the 24VDC line

So fits his description.

Yes, I've watched more of it now.
It is a disconnector.

The current measurement is using an in-line Shunt, not a CT.

<ETA>
But I was a bit surprised how confused he seemed to be about the function of the shunt. He zoomed in on it and scratched his head and wondered what it was. And yet the PCB screen print clearly showed what it was, if it was not obvious enough from inspection.

I don't think that was the case at all - I think he was just intrigued by the way they'd implemented it as a special insert rather than just using the copper bus bar.

I've watched enough Big Clive, EEVBlog and so on to know that there's a special ability to miss the obvious that kicks in as soon as you're talking to a camera.
