I think Ireland had it's own slightly strange implementation of BS546. I've never seen a multiple adaptor for anything other than the 15A socket outlets.
Did you not have the adapters to allow multiple 5A BS546 plugs to be connected to a 15A outlet? They were pretty common here. as were the ones which were all 5A, i.e. a 5A 3-pin plug to a 5A 3-pin socket plus two 5A 2-pin sockets, or a multiple 5A 2-pin.
BTW, the 27A MCB was used for 4mm before we changed over to (ahem) International fusing sizes.
Although for radial circuits 20A is the most usual here, at least in residential work, the Regs. allow a 30A cartridge fuse or 30/32A MCB to be used for a radial circuit wired in 4 sq. mm. Rewireable 30A fuses are
not permitted for such radials however.
