Hi guys I'm sending Brad some pics for this. Its a 240 volt variac which runs from 0 to 260 volts. But I cant for the life of me work out what the socket is. It does not fit a standard 240 volt plug. Its three prongs . Please correct me if I'm wrong but I should be able to change to a normal wall socket. Thanks for your input in advance.

It is a standard British power socket. Yes it can be swapped for an Australian socket. Bunnings will have surface sockets in stock.

If the hole in the cabinet is too big for a surface socket to cover you would be better off with a mounting block and a standard pattern single outlet.

Well guys I put a aussie power socket on this baby and powered it up and it worked perfectly. I tell you what the british design is not real bad. There is no access to the active or neutral unless the earth is plugged in.

And, traditionally, there's a fuse in the UK plug like this:

Shutters can be had on Australian outlets too. They are mandatory in certain parts of hospitals and optional for the home. In all reality though, they just contribute to early failure of the outlet if plugtops are inserted and removed often. It is also quite difficult to insert a two pin plug into these outlets as they are also actuated by the earth pin.

The Poms put fuses in their plugtops because their home wiring is in a ring circuit, which is illegal in Australia.
