Strange Grelco adaptor... a question for the 'vintage' sparkies

[Lucien Nunes]

I'm not usually stuck for ideas about old plugs but this is a new one on me.

See pics...



It's just like a regular 2-pin 5A Grelco, except for that peg leg in the middle. The middle holes in the sockety ends don't contain any contacts. The L&N pins are normal 5A gauge and centres.

What would it fit and why?

*bang* "What was that?!"

Not guilty! Well, except maybe once at the CNIT in Paris although strictly speaking I didn't plug them in myself. But we had more to worry about than a couple of smoking cabs. The best bangs I've had out of Soca was on a outdoor show that was packed down in the rain and left shut in the trucks for 2 weeks, then built up and plugged straight in. One day I'll tell some stories about that one, was in Russia, had some interesting 'challenges'.

E2A Snowhead I haven't read all of that thread but it's mostly about the USA stage pins, where the regs are quite different from anything that ever applied to BS372 round-pin UK plugs. The theory of making it non-stackable is interesting, you have a large hole in the socket and a small pin on the plug, so that you can put plugs and adaptors into sockets, and plugs into adaptors, but you can't put adaptors into other adaptors. This is a bit like the Wylex plug where you can stack 5A into 15A but not 15A into 15A. But as you say, what kind of socket?
