Chris,

Don't worry about trying to match some old socket. Go with some new sockets
and plugs as long as they have 4 prongs arnd are heavy enough to carry the
current. Better yet, hard-wire it in and get rid of cords on the floor.

Hi all,

I have a box of salvaged three phase sockets. They're pretty old and of an
all-metal construction. I'd like to mount a pair on my phase convertor
(when I've built it) but I don't have any plugs to match the sockets. They
have 3 phases, a neutral and an earth, but I don't think they're CEE
sockets. As far as I know the 3P+N+E CEE sockets have the pins arranged in
a pentagon, whereas these have four pins in a square and the earth in the
centre. There's an emblem made from an interleaved "M" and "L" on the
front, and you rotate the plug to switch on the power. Here's a pictu

Any idea what they're called? That way I might stand a better chance of
finding some matching plugs.

Best wishes,

Chris
