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.

  • My diagram is basic and I actually only need one of the three options with two 2-gang outlets. The radial is near the midpoint of the ring so the resistance around each led back to the MCB should be similar.
