Outbuilding consumer unit

Coming back to this wretched EICR at my daughter's house


An outbuilding used as an office is supplied by a 6mm^2 T&E carried from the house on a catenary wire.and fused at the house at 32A (RCD protected)

In the garage the the 6mm^2 is split into a 2.5mm^2 for sockets and a 1mm^2 for the lighting

This is coded C2 for the inadequate protection and C3 for using T&E outdoors.  Both of which seem reasonable


Q1  Can I put a two unit CU in the outbuilding with just a 6amp and 16amp MCB or do | need also to provide a two pole switch?

Q2  What do the great and the good think of using T&E outdoors?  Should I replace it with hi-tuf?

  • "The purpose of a fuse, breaker, or whatever is not just is not just overload protection but also short circuit protection"


    I`d modify that a bit.

    An OPD (OCPD) might be used for one or more of three reasons:-

    1/ Overload.

    2/ Short circuit

    3/ Earth fault.


    Other methods might also be employed instead of or in addition to such. RCDs , limited loads by design, are two examples
