Just thinking...what about domestic 3 phase boards? 4 pole isolators?If ordinary persons are using the equipment which equates to households then the main switch must isolate all poles.
I suppose it depends on the situation.
Just as an aside....I wonder if Part Peees have been issued for work on some of them big houses (Buckingham and Windsor, for instance).
I'll bet the NIC say they should.
Or Houses of Parliament......plenty sleep in there and call it 'home'.
