Unfused spur.

Zoomup
Hello All,


Could an unfused R.C.D. protected spur, from a complient ring final circuit, supplying a single outdoor socket via 1.5mm2 6242Y cable of max. length 300mm through a brick wall from an indoor socket outlet be considered compliant?

    As the circuit is protected against overload of 13A, is RCD protected, and presumably is at a point where a short circuit disconnection time is less than 400ms, why not Z. The adiabatic for the 1.5 conductors is presumably satisfied (I would be very surprised if not, and the Earth fault is protected by the RCD) then why not. It isn't in the OSG, but no immediate problems seem to be present.


    Strange things are happening with my edit! Are you carrying out an EICR Z, or have you run out of 2.5?
