[QUOTE="roys, post: 502706, member: 5044"] Thank you for that, good call. Under a £100 so comfortable with that. Curiosity got the better of me, When my wife was out this morning, I switched of all the breakers, removed the 10mm earth to gas, none on water as it’s all plastic, and removed earth to board and put my Fluke on mA in series with it, read 1mA, I then put on just the RCBO that was causing the problem, the reading went up to 7.5 mA, switched of double pole to tumble dryer down to 5.5 mA, then switched off double pole to washing machine down to 3.5mA then switched of double pole to combi down to 2.5mA So nothing dramatic there just the SMPS on the equipment with slight leakage as expected. Had a bang along the plasterboard following the cable route with meter on min/max, no change. so next step replace the one usb socket on that circuit, leave for say 6 months to see if it trips, if it does replace RCBO. I hate random changing but I have done testing with no fault found. When I go away from home for anything more than 2 days I will plug the fridge freezer into the downstairs radial. Think I need a datalogger as well 😀 [/QUOTE]
