I have several appliances in the kitchen plugged into an extension strip - microwave, radio and coffee machine. The circuit doesn't have an RCD at the moment (to be upgraded next year, finances permitting) but I'm wary of not having protection here. Is there such a thing as an extension lead with an RCD already fitted? Any recommendations? If I plug the extension lead into a plug-in RCD pro tem, will all the appliances be protected?
