    Evening... I always use my OSG to find R1+R2 when needed for designing a circuit (staying withing the Zs limits), but I wondered if the same table is somewhere in BS7671? Its table I1 in the OSG. I've hunted high and low so I expect it's just something that the OSG offers and isn't in BS7671...

    BS7671 Vs NFPA-NEC

    This would sort out most of the dross in this trade. A legally binding code and compulsory registration. Yes I know there’s a lot wrong in the NEC, there’s far more wrong in BS7671.
