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?

  • "Greater safety afforded due to additional protection, twice. "


    I`d question twice Zoom lad.


    Theoretically say if you take a 7% failure rate then two cascading RCD faults might mean 0.49%.

    That would be the expected maximum protection though.

    If they are in the same enviroment and of same make and class they might both fail for similar reasons so I think difficult to achieve. but perhaps better than twice the chance of one RCD
