I'm going crazy, for years I've used what I call chock block connectors and I particularly like the versions with a small metal leaf that protects the wire as the screw clamps down on it. I'm looking for some 3A versions but cannot find any, so far I've tried, RS, Farnell, Ebay, Amazon, Screwfix, and Wickes. Does anybody know where I can lay my hands on some?
