Originally a Sp DB,now 3pDb 400v.
The plans have not been altered to suit,so circuits are the same.
Would you worry about the rings are on different phases & close to each other.
 
Socket outlets simultaneously accessible when on different phases?
When the OP says different rings, I'm assuming he is referring to the socket outlets.
If he is referring to the actual cabling then maybe no problem.
 
Personally I would of made the rings all on the same phase,but I didn’t connect DB.
Or even asked for revised drawings,but once again you get hassle of other sparkies who know better....??
 
Lighting used to be spread across phases to lessen the stroboscopic effect, as long as the sockets are marked up then there should be no issue

I also am interested in why you think this does not comply to regulations, there is no issue at all here and if I recall there was once a regulation which called for them to be marked with a caution label if within arms reach of each other but I don't believe that exists anymore.
So in your own opinion what are the dangers or concerns here?
 
Don't know off hand but will check regs when back in the office.
May even be excluded in the 18th now but regardless of that, always seemed 'good practice' to prevent simultaneous contact!

Maybe this is the reg that remember !!! Perhaps not valid anymore with the 18th??

I think it dates back to the 16th and was lost when they redefined the regulation about marking switch points and outlets in excess of 230v, this was later altered to 230v to Earth which thus covered standard 3ph 400v and meant no labelling was required.
The original regulation is still in use but the goal posts where moved in its effect.
