"Generally speaking the exportation of a TN-C-S supply is the decision of the local DNO and only done with their permission. In the absence of such permission it would be recommended to use a TT system and RCD protection. However most DNO's will allow such exportation to an outbuilding provided it is 2 meters or less in distance from the main
building.

I advise that you check with your local DNO as to their requirements."







2 meters or less in distance from the main
building.

OPEN TO CORRECTIONS BUT, this is stating that, if you want wiring done in garage, conversion etc further than 2 meters from your house, it has to be a TT system??????

Im having a lazy sunday and have ended up reading countless threads on exporting PME!!! Never knew it was such a hot topic!!! To add my two pennies worth i would always run a PME supply to an outbuilding if possible. If in doubt use your books to confirm the cables/volt drop will be ok etc but invariably they check out fine.. I am always suprised at the relative csa of swa armour, always always more than you would think!!
