Discuss Why does the UK use rings for sockets? in the Electrical Wiring, Theories and Regulations area at ElectriciansForums.net
because to crate a 32A radial, you need to use 4mm or 6mm cable. and a radialcould well end up with the last socket alomost back to the board, so the extra leg of a ring might be only a few yards.How does a ring use less copper?
A radial is basically a ring without the return cables. Confused!
As already mentioned by @telectrix because the ring can use smaller cable for the same overall rating. Almost all final ring circuits in the UK use 2.5mm cross sectional area cables for a 32A rating, to do the same total current as a radial you need to use 4mm (saving in copper of typically over 30%) or even 6mm if the length is great.How does a ring use less copper?

Schneider produce rcbos with no neutral fly lead on their acti 9 isobar P DB’s, think the rcbo’s are only single pole tho.Do you think that manufactures will standardise with the rest of the world and produce dual module RCBO's and get rid of the flying lead?
no neutral or no earth?Schneider produce rcbos with no neutral fly lead on their acti 9 isobar P DB’s, think the rcbo’s are only single pole tho.
No fly leads on eitherno neutral or no earth?
Because its ours. Long live the RFCBecause we are British and don’t like change and have to do everything differently to the rest of the world
