If folk post here saying that they are outside the UK then I assume that they are telling the truth, not lying to us.If folk are going to post questions in Electrics UK using locations outside the UK, it is assumed they are in the UK: lots of users here have non-UK locations.
That is indeed what the regs say, and they say nothing directly about how (1) has to be achieved. That make me wonder why they bother to specify condition (1), since the required disconnection time will inevitably be achieved by (2).Supp bonding may be omitted anyway if ALL three of certain conditions are met:-
1...Automatic disconnection times are met.
2...All circuits of the location are 30mA RCD protected
3...All pipework of the location (if conductive) is effectively connected to any bonding required in the installation.
What you say is not unreasonable but, as you say "it [the regs] doesn't say that".As the RCD may only be considered additional protection I maintain '1' should be met without reliance on the RCD although I admit, as is so often the case, it doesn't say that. The same as, I believe, 'Max.Zs allowed' on certificates should still be that relating to the MCB and not 1667 for every circuit.

I think you may have missed my point. No-one is denying that all conditions must be met in order for supplementary bonding to be omited - it's a question of how they are met.I think the fact that ALL conditions must be met enhances the point that RCD is supplementary and without it being present then supp bonding must still be carried out.
