When discussing terms used in the electrical industry on this board, we should keep in mind that some terms are different between various locations around the world, and may lead to confustion when questions are asked of those of us in the USA.
Can someone offer to post the terms to be used so as to avoid confusion.
For example, what is a "ring circuit" and a "spur" and does a "fitting" mean something like a "device" and others .. get the picture?
Joe, You make an excellent point. There are some substantial differences in terminology just between English-speaking countries, let alone considering how foreign terminology might be translated into English.
When talking with you in the States, I try to use terminology that will familiar, unless making the point requires use of the British terms or there is no easily interchangeable equivalent.
So, defined in terms that should be familiar to Americans, here are a couple to get you started.
Ring circuit: (Peculiar to UK and a few British-influenced places.) A branch circuit in which phase and grounded conductor are wired in the form of a complete ring, starting and finishing at the C/B terminal and neutral bar of the distribution panel. There are thus two paths from the panel to any point of utilization. In the case of NM cable or single cables used in PVC conduit, the grounding conductor is also wired as a ring, each end being terminated at the ground bar in the panel.
Spur: A branch cable feeding an outlet which takes its power from a single point on a ring circuit. "Outlet" in this sense may be a single or duplex receptacle, or a hard-wired connection unit incorporating a fuse to feed a fixed appliance.

Excellent point Joe, I have been meaning to start a topic along these lines in the non US forum. We could use a glossary of terms, I am not familiar with US terminology. I have only worked in the UK & Australia, so consequently I am not comfortable using US terminology in the non US forum. Do you think such a glossary may be possible so that we might all understand each other better?

i totally agree with Joe, as an electrical contractor here in the UK i have some trouble with the terminology used within the Forums (not all of it, just some of it) IE what we call a socket outlet, you call a receptacle,
I gather that a panel board to you would be a mains distribution board to us,
and a CB would be a MCB (miniture ciruit breaker)
Is a GCFI an Earth Trip, or RCD to us,
as you see we over here would like to know more of what you do, and call it, over there. !
the more information the better, also what is a `wirenut` i have been called a few things before but only once have i been called that !!!!
