I have two standard 30A rings for downstairs/upstairs power which I am planning to update soon to overcome some legacy DIY issues. I've seen it mentioned a few times that radials are more in vogue these days, which I guess gives 3 options:
1. Keeping each ring as 32A/2.5mm
2. Split each ring into two 20A/2.5mm radials
3. Convert each ring to 32A/4mm radial
In principle all these would be options, although (3) would be the biggest change. The cable cost, RCBO positions, cable costs and testing requirements are not particular concerns - I am trying to understand what factors would influence the best approach.
thanks, Radweld
(for info, this will probably form part of a larger, notified project and I'll do this work myself if the BCO is reasonable)
