[QUOTE="Rob_the_rich, post: 394082, member: 8419"] you have an rcd in the house cu and an rcd in the garage cu. They do not [B]discriminate. [/B]ie, if a fault occurs in the garage, either rcd could trip. This could be against regs 531.2.9, 536.1 and 536.3 [B]if[/B], for example, the house rcd also protects a lighting circuit covering a stairway. I am thinking of what constitutes a "danger", as I am not sure whether it is required for "proper functioning of the installation" You could have a word with the developer to possibly rectify this, free of charge, and perhaps add a couple more double sockets in the garage as a goodwill gesture. There may be a reason for putting the garage supply cable on an rcd in the house cu, eg cable in wall at less than 50mm, and the devices just might discriminate according to the manufacturers, but get the developer to confirm this.
