[QUOTE="Andy™, post: 41457, member: 2012"] the weakest part of a ring is the cable, only being rated at 27A compared to the breaker of 32A. since not all the current will flow through one leg of the ring, there isnt usually a problem. depending on where the load is connected, there could well be 27A (possibly more) flowing through one cable. obviously its not a good idea to add another weak spot (a 24A connector). not really a problem using them in radials with a 20A (or lower) breaker If there was a major problem, then 7671 could say rings cannot be used, unless its wired in 4mm or a 20A breaker (or maybe this could be a good market for 25A breakers?). in which case you might aswell make it a radial [/QUOTE]
