Hello lovey electrical people. Another question, please.

I have just tried to plug my spanky new 400v 3 phase fan heater (specifically one of these)



It has one of these on the end:

75986

Which looks spiffingly like it will fit in here:

75987

Except it won't. The plug is too small for the socket.

Now I need an extension anyway, so it's not the end of the world, but what type of plug and socket do I need on it?

TIA!

There are 3 types of TPN+E commando plugs / sockets with different diameters. 63 amp (69mm), 32 amp (63mm) and 16 amp (56mm).

Work out the size of the plug and socket and you are sorted.
