3Phases+Earth, is quite common over here in Industrial work, no Neutral, this is used for 400V motors, wired in Delta, but are still required to be Earthed.
Hence, the four pin plug. [Linked Image]
Paul, I think that the RST/UVW directive came from the EU, correct me if I am wrong, but I work now with a Dutch Electrician, he says that the use of these, has been in use for some years?, bugger me!.
Over here anyway, the standard phase rotation,R,W(Y),B, is called L1,L2,L3, in that sequence. [Linked Image]:

The RST phase designation has been phased out long before EU, nowadays only L1, L2 and L3 is used.
Yes, earth was one pin, but the case had a grounding screw as well.

Texas,
I think that we have had a conflict of terms, here, caused by me.
What I meant by EU, was Europe in general.
Sorry, mate, Kick me, if you must!.

Oh boy, don't get me started! Consider yourself kicked... [Linked Image] [Linked Image]

Europe "in general" is a collection of countries filled with mostly friendly people whom I have nothing against. On the contrary, there are a lot of attitudes and approaches in Europe that I prefer to the prevailing state of affairs that now exists in England.

The European Union, on the other hand, is a bunch of corrupt, undemocratic, dictatorial bureaucrats who think they can ride roughshod over the rights and wishes of the people of Europe to achieve their aims. They've even suggested that criticism of the EU and its (many) branches should be made illegal! So much for freedom of speech, eh?? [Linked Image]

O.K., I'm getting off my soapbox and back on topic now....

I've seen the RST phase designations in 1960s documentation on equipment from Europe, so it was in use at least that long ago, before the EU started meddling in electrical matters (before the EEC even became the EU in fact).

Whoa, Paul,
I realised that there was a wee bit of ill-
sentiment from the UK, toward the European Union, but I never thought that it was that
strong.

Uh-oh... With all respect Paul, perhaps we better keep ECN (at least the non-US section) free from politics? There is a rather large chance that we (all of us) share views on matters electrical, but have opposed views on politics. This would be even more sensitive should there come members from, e.g. the Balkans or the Middle East.

Sorry guys, I didn't realize I was straying into the field of policitics. It's just that it sometimes seems that everything the EU gets involved with ends up being an expensive disaster for everyone concerned! The ill-conceived EMC Directive and the "CE" mark is an excellent electrical example.

I didn't mean any offense to any of our members in Europe personally or to their respective countries.

Yeah,
Sorry Paul, for leading you down that road,
in the first place.
I agree with C-H, we have enough politics in our lives as it is, lets keep ECN free of that Rubbish!.

I was probably feeling particularly antogonistic after reading some more idiotic EU regulations.

As I said, I'm anti-EU, NOT anti-Europe, so I hope our Continental friends don't feel that I'm in any way attacking them.

Let's get back on topic..... [Linked Image]

Paul,
What type of plug and socket combinations,
do you have in the UK?, for Industrial situations these days.
Are these the same as Scotland, David could you please help?.
