[QUOTE="ProDave, post: 499119, member: 6969"] Thanks for the clarification, that is not a common configuration (thought it is good) and sorry for doubting your descriptions. Is it the Garage rcbo that is tripping (I note the water mcb is also off) For anyone else, here is your picture [IMG]https://talk.electricianforum.co.uk/uploads/imageproxy/Image.jpg.07efb4329aa5fc28681211578243ee5b.jpg[/IMG] I suspect he used a 16A rcbo as there is only a single 2.5mm cable. A better solution would be pull another 2.5 cable through and make the two double sockets in the garage a 32A rcbo as a ring final. The problem at the moment is you don't know if the rcbo is tripping due to over current or earth leakage. That wiring alteration and going up to a 32A rcbo should eliminate inrush current from most power tools. And I would ask the electrician to PAT test all your power tools. [/QUOTE]
