[QUOTE="SPECIAL LOCATION, post: 58750, member: 250"] Basically your normal tests e.g. R1+R2, Zs, InsRes, Polarity etc.. relate to a final circuit or distribution circuit that has its own overload protection device, (circuit breaker), eg. BS3036 / BS1361 / BSEN60898 / BS61009 etc.. So if the circuit breaker is part of the Garage CU then thats the point where that final circuits tests are done from. The bit from the house to the garage CU would be a Distribution circuit (i.e. supplying a distribution board or CU, as opposed to a final circuit). which has its own overload protection somewhere on the house CU. so the Distribution circuit ending at the garage CU, would be tested back to the house CU 20A MCB. All of the individual circuits need their own full set of tests done! ;) [/QUOTE]
