hi, am going to be running a new supply to a detached garage and am wanting to seperate the building from the main houses PME and have the garage on its own TT supply. The feed to the garage will come from a 32A breaker, RCD of course..... just wanted to know what csa earthing conductor you guys usualy run? Just getting my head in a mess reading the dam regs! Would you size it based on the conductor sizes of the armoured cable to the garage or still size it on the house supply??? Thanks all!
