[QUOTE="Phoenix, post: 419704, member: 8133"] That seems a little odd to me, just over 4mm² would put it at 7/036 which translates at 4.59mm² but the cpc should be 7/029 (translates as 2.9mm². Even 7/029 which was normally used for rings had a 3/036 cpc (1.97mm²) It wasn't until they tried to go metric that things got screwed up and it took them the best part of a decade to realise that 1 wasn't actually at least half of 2.5!!
