Plug in solar, what do you think?

A final circuit is a final circuit if it serves points of utilisation.
If you use an FCU on say a spur then that itself is a final circuit after its fuse (but it could feed a lower value fuse to yet another final circuit.
The Ring Final Circuit or Radial Final Circuit is also the distribution circuit for the FCU too.
Good innit?

Ho, and you might have a Ring Main in the street and you might have another type of Ring Main at a Distrubution point such as a power station, where sections can be locked off and the remaider used as a Radial.

I agree with @ebee it is not PC (politically correct) to refer to a military PC (police constable) as a MP without first saying what it means. I know we do forget that when talking about narrow boats, a RCD is the recreational craft directive, and not an electrical device, and in the main when we talk about a boiler, we don't actually want it to boil water. Even when it does, when it changes steam to super heated steam, is that still a boiler?

However, when we are discussing a fairly confined bit of tech, then what is under discussion will be fairly obvious, even if the short form of initials are used. When discussing smart meters, IHD, can only possibly mean an In Home Display.

True, and we all do it, all the time, nearly always with no risk of ambiguity or uncertainty.

However, "RFC" is a different, and unusual, kettle of fish since, within exactly the same context, it could no less 'obviously' mean "Radial Final Circuit" than "Ring Final Circuit" - so one can only know what is (probably!) meant if one is aware of the common 'convention'!

Well I had no idea what IHD might mean, why should I? that is my objection.
As an Electrician on an Electrical Forum I usually know what most things mean or are intended to mean even if the wrong terms or names might be used.
I am aware that folk often use the word Spur to mean an FCU (switched or not) etc etc but IHD no not me and others I think, we even know what people mean when they say Bulb even if we joke with them that Bulbs grow in gardens and lamps go in lampholders.
A few common things used correctly or incorrectly we can get by with but a lot of things are not quickly obvious to many, IHD is one of them I think.
Now I know what was meant in this context I might well recognise it if used again.

Almost every customer with a smart meter, will be aware of what a IHD is. I am surprised that someone 'in the trade' might not know, when the IHD was mentioned in the same sentence as the smart meter.

Only in the last year did I know what in home display was. And smart meters have been out a long time. The same applies to SOC, once I realised it was state of charge, it seemed so obvious, but it took some time to work it out.
