Yellow for 110V, blue for 230V, red for 400V. Other colours for special applications.
16A, 32A, 63A and 125A, 2P+E, 3P+E, 3P+N+E.

You know what I'm talking about. They've been around for 50 years, but no-one can yet agree what to call them.

The official name is "plugs, socket-outlets and couplers for industrial purposes" according to IEC 60309 (formerly IEC309). They go by lots of different aliases... IEC309, BS4343, CEE17... but a lot of people use a manufacturers' name or trademark: Commando, Marechal, Ceeform, or just the current rating 'a 32A plug' or something relevant to them 'Caravan plug'.

What do you call them? Does it depend on who you're talking to?
 
I grew up calling them industrial plugs..
Depending on who I’m talking to though, also call them commando plugs..
At wholesalers will ask for them by colour, voltage, current and number of pins... they still get it wrong haha
 
BS4343.

There can be differences if not bs4343 and a particular manufacturers design.
Pin diameter, key slot.
I’ve had cheap caravan leads stuck in our Rolec hook up points because of differing measurements.
 
Commando plugs always through my training. Is that the MK name ?

I sometimes do work for a commercial printer company that call them shark plugs, probably another brand name.

We use a lot of shark plugs, they're made by PCE. We use them because they do an all black version which is very fashionable in theatre.
 

CEE FORM seems to me the best name to avoid brand and refer instead to 'Certification of Electrotechnical Equipment - CEE'

The link shows the colour coding table and rules for colour, voltage, frequency, ac/dc combination.

Re: Davesparks black shark plugs - black has entries in the colour coding table.

Trade names work when there is only one market leader, Hoover, Sellotape - etc. Otherwise it gets confusing as the above comments prove. In the RAF WD40 was called Rocket - because years previously it was originally made by a company called... Rocket. Now everyone calls it WD40 - even if it's GT65 or similar.
 
Originally made by the Rocket Chemical Co. The company were trying to develop a liquid which displaced water and with the 40th formula they succeeded hence WD40 (Water Displacement, 40th formula).

'Ceeform' is common in the entertainment lighting industry, but I thought it was originally a trademark of Mennekes Elektrotechnik GmBH who were one of the first manufacturers. A quick browse failed to find evidence for or against this, maybe someone can confirm?

The black PCE Shark series have all black bodies to reduce visibility, as distinct from black to denote voltage range. The data label is coloured to indicate the voltage (e.g. a 230V plug has a blue label) which in the case of the plug is concealed when inserted in a socket.

I'm not aware of any deliberately non-standard plugs that are partially / forcibly intermateable with BS4343 (STOP PRESS... BS4343 is withdrawn and replaced by IEC 60309-2). I'm thinking these are actually substandard or incorrectly assembled plugs that are supposed to be to IEC 60309. I've seen people manage to put them together with insert in the wrong orientation, could that be it?
 
all depends on the plug. if it's a qualified plug, call it "mate". if it's an apprentice plug, call it "Oi You"
 
Within the events industry, it’s always a ceeform, although not all domestic sparks are familiar with this, or indeed 7909, however all sparks are familiar with them referred to as commandos.
 
It's MK's trademark and well known now, but I don't recall them having much market penetration in the earlier days of IEC309. I wonder how high their profile is outside the UK? It would be ironic for an internationally standardised design to be best known by the local manufacturers' names. The USA knows them as 'pin and sleeve' which is a rather broad description, but distinguishes them from plugs with flat prongs or blades which have always been more common there.

Schuko is also a trademark, owned by an association rather than any one manufacturer. The name is known globally, and is pretty much the only standard name for that type of plug in dozens of countries. You can ask for a Schuko plug in Spain, Iceland, Hungary or Switzerland, all of which have very different languages, and you will be understood. The word 'Schuko' is a contraction of 'Schutz-Kontakt' meaning earth contact, but this is incidental to non-German-speakers.

Perhaps we could do the same for 60309. We should think up a catchy name and popularise it, form an association, then once the name starts to gain traction we sell licences to manufacturers who want to market their 60309 product using that name.
 
Emails from event organisers often refer to them not by name, but by size/flavour - e.g. 63/3, 63/1, 32/3, 32/1, 16/1. Some believe there's a 64A variant, presumably because 2x32=64... but no one's ever requested a 128
 
In telecoms it is Commando, doing events it was Ceeform, it did get confusing at times...

I vote for "nubbin plugs" due the the locating nubbin on the plastic moulding to ensure correct insertion.
 
Well if we can call them any names we want, I vote for "Tarquin Fin-tim-lim-bim-lim-bin-bim-bin-bim bus stop F'tang F'tang Ole Biscuitbarrel"
