[QUOTE="SPECIAL LOCATION, post: 499114, member: 250"] What sort of "power tools" are we using? A 16A Type B RCBO could be tripping due to start-up current of the "Tools" you are using.... i.e. Tools ok off a 32A ring.. but trips on a 16A radial! Why did the electrician only rate this circuit at 16A? Was it just what came in a pre-equipped CU, or is there some obscure design reason? I am guessing either a 16A type C... or a 20A may stand a change of working better... Guinness [/QUOTE]
