just been having a debate with my mate regarding the regulation below
537.2.1.3
" where a installation or a item of equipment or enclosure contains live parts connected to more than one supply, a durable warning notice shall be placed in such a position that any person before gaining access to live parts, will be warned of the need to isolate those parts from the various supplies unless a interlocking arrangement is provided to ensure that all the circuits concerned are isolated"
so the way he interpreates it is that say at the bottom of the stairs you have a 2 gang switch, up lights down lights, then in the mains board up and down lighting circuits.
in that switch there are 2 circuits so you isolate the down lights open up the switch the up lights side of the switch is still live.
now i can see where he is coming from but in the above reg it says " connected to more than one supply "
now i would say that the 2 circuits in question are on the same supply, just different circuits.
anyway your views please lads
