What is the protocol. Am i right...

hi there ..when working out current carrying capacity for ring I found with correction factors the current rating to be 43A, and the tabulated rating to be 27A..now am i right in thinking that as it is a ring the circuit can be treated as two halfs, ie permissible to have 54A( 27A per half of...
