Hope someone can help. When finding the cabling current capacity for a ring (wired in 2.5), would you use the data for 4mm in either/or table D5 of BYB or table 7.1 (11) in the OSG ? As the ring circuit is in effect 5mm !
Looking at the OSG ref methods; a 2.5 with ref method 101 says 17A, with 4mm its 22A. Atm the ring (run through loft covered in insulation) is on a 32A so needs swapping out. Can anyone advise
