phase seperation

[the pict]

Items of current using equipment on different phases is there a reg for a minimum distances apart, something raised in discussion yesterday someone mentioned 2 metres but I cant track a reg, other than phase barriers in an enclosure I cant remember anything else

I don't think I'm understanding the question.

L1 drives a lathe, L2 drives a milling machine, physically should they be a minimum distance apart, I think that some earlier edition deemed a min of 6 ft,

Fixed wired appliances - less of an issue and there are lables you can use to indicated 400V between devices.

Now sockets are a different matter and i would do all i could to keep the distance a very long way apart, but its the labeling which is required.

Used to be in earlier editions but now there is no requirement...

labelling is only required when the nominal voltage to earth exceeds 230V. 514.10.1. QED.

There is still advice (BRB 514.10.1) regarding non-ambiguous labeling between separate enclosures having a voltage exceeding 230V which is simultaneously accessible.

I encounter numerous large grid switches for numerous lighting bays and loads of times different phases present
Usually poor labelling too but as said sockets are advised to be kept apart
