I have a beautiful old toaster (the "flip" sort not "pop-up" that I acquired after a friend's mother died - actually, I used to have several from the O&S of my father who was a great fixer-upper, but I suspect they went missing in a house move) and I fancy putting it back to use.

It needs new flex - and I have found sources for fabric covered flex - but the thing that is alarming me at the moment is that it used twin core - so there was no earth - and the only thing keeping the elements off the metal body appears to be some thin mica, in some cases mica washers.

I am tempted to use a three core fabric covered flex like an iron, and add an earth, taking care to keep the earth connection well away from the others!

Does anyone have any comments or knowledge on current (no pun intended) UK relevant electrical standards?
