Having been asked to fit a new weatherproof external socket to a domestic property, it's not feasible to fit the easy way, back-to-back, but perfectly possible and, I would expect, acceptable to fit it at the end of a 2m horizontal length of PVC conduit. HOWEVER, the client would also like a new internal socket back-to-back from this position. Is it considered acceptable to extend the ring circuit through the conduit to this new location - OK, I'd upgrade to galv steel - whilst keeping the external socket as a fused spur? Location is adjacent to the path from gate to front door. All other requirements (RCD etc) are satisactory.
Thanks for those comments, chaps. (Not American - don't use "guys")
Yes, I'm fully aware of the regs in respect of RCDs (they're already present) and structure of rings and spurs, also of the desirability of an indoor isolator.
The point in question, that I obviously didn't express with quite the required clarity, was really whether part of an 'indoors' circuit i.e. the cables of the ring extended to serve a new internal socket, could be run 'outdoors' in conduit on the face of the external wall.
David's comment about fault conditions relates, I presume, to possible loss of neutral on TN-C-S, which indeed is the supply characteristic. I have slightly lower confidence in the ability of PVC conduit and saddles/clips to withstand probable impacts from users of the path.
