The ones in France are since the earth pin forces the schuko plug to go one way.
Indeed, but it may be the reason why double pole protective devices were initially used. It may be simply for traditional reasons now.

I thought petrol stations had a big book of additional regs though (and you can't have TNC-S I believe) - is it covered in these? Daz
Yeah I thought we were on about TT systems which petrol stations are.
Most circuits Are protected by DP RCCBs but I've seen a few sp breakers so I was just curious. No one has ever mentioned needing to isolate the main section breaker if I was to work on a circuit which doesn't have DP isolation.
