[QUOTE="Mr_Bean, post: 499116, member: 32932"] Thanks for such prompt reply's. ProDave - apologies for any confusion, I have failed to find how I can edit my original post. The consumer unit consists of 1 Main Switch and 6 RCBO's, as per the image here: https://ibb.co/4FF8y5H 3rd from the left is the problematic RCBO. Special Location - You may well have spotted the problem! How had I not noticed that the house sockets were on a 32A and Garage sockets on 16A?.... I do not know why a 16A was fitted, when the electrician came to replace the RCBO last time I asked whether a different 'Type' of RCBO would be worth trying but he seemed reluctant. The 'power tools' that have caused the problems include: 240W Orbital Sander 450W Hedge trimmer 700W Drill 1100W Vacuum cleaner 1500W Router Could the start up current on each of these exceed 16A? Geoff1946 - Thanks for the suggestion, but the problem seemed to happen just a frequently when using a 20m extension lead. [/QUOTE]
