In fact you can see in the pictures it says 13AWG which is 2.5mm. It hasn't seen any hard use yet so remains to be seen if it will work well, but it switches on without killing me or catching fire, so that's a start!

Joe A picture paints a thousand words I tend to point people to your P/S vids (if that is ok) as they are an excellent way to show how easy they are to build. There is one point and you have it correct is that you must not but an earth (ground) to the bolt on the top of the transformer that runs through it. It is ok at the bottom end ie the plate.

No worries Clive - just glad they are of some use to people!
Btw I have made a playlist of the two videos here to keep them together: https://www.youtube.com/playlist?lis...zD30sZjtp_VyqY

If you do die can you get some one to send me a PM saying get 4mm wire lol ;) I missed that but actually managed to read the part number off the connector blocks and find them on ebay lol.

Those connector blocks are pretty huge and a total overkill! I recon 2.5mm should be ok as it is rated for 30amps
