Splitting Load. Is it safe?

Hey guys piggy backing off another topic....again...totally irrelevant to topic but it made me think of it
I was once told that if you had for arguements sake a socket on l1 and another on l2 they had to be a certain distance apart (i have 2m for some reason) is this a reg or just best practice? I was told the reasoning was is that if u had to points on two circuits fed by differenr phases you want them so far apart other wise you could potentially have someone get 400v if they had contacr between the both?

Up until the 2011 amendment to the 17th Ed there was a requirement to put notices in place where voltages between separate enclosures, which were simultaneously accessible exceeded 230v, this is no longer the case. Trying to keep voltages at 230v between enclosures has never been a requirement more a case of good practice which many people still believe today, it has never applied and still does not.
If you have pre and post copies to 2011 see Regulation 514.10.1

Micro brewery... Brewing Vat has 2 elements, 9kW and 6kW. Done the calcs and each element will be fed with 6.0mm XLPE. no problem.My query is would it be safe and compliant to split the 2 elements across 2 phases in order to balance better. Can't see a reg.preventing this, but something nags about having 415V PD in what is essentially a single appliance.

You getting ready for Christmas then Tel, by the looks of it.

unfortunatelyit takes several weeks for the brews to ferment etc., so enen if i got them up and running before xmas, the first drinkable ales would be February/March. in time for easter though.
