4mm Radial off a 32A Ring

WireWeHere

The ring is 2.5mm fed by 32A MCB. I know that I can run a single fitting (e.g. 2-gang socket) off a ring as a spur. Alternatively, I believe I can run a fused radial off the ring as the fuse stops excessive current doing down the radial. However, can I run a 4.0mm radial (unfused) off the ring as a 4.0mm radial is rated to carry 32A (single phase)? It feels logical as you can have a 32A 4.0mm radial on its own and the ring supports 32A. I appreciate logic doesn't always apply though.

  • How is the current split across the two legs of the ring?

    Why not just extend the ring?

    The current is reasonably well split.

    I'll look at extending the ring but don't know as easy and I'm keen to know what's possible, what's frowned on and what's a no-no.
