[QUOTE="mort2376, post: 537211, member: 25787"] I would put 4mm radials in probably 2 off. Then you could fuse at 32a. Up to you if you choose to fuse them at 20a to start with. I would use rcbos rather than a split load board more as a safety issue so a group of circuits did not go off which could cause an injury. If the sub main is wired in swa then it's fine on an mcb but you could go belt and braces and put a 30ma time delayed rcd at the mains to cover that circuit as additional protection. [/QUOTE]
