And the 17th I believeDon'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!
Thought the idea was to try to prevent simultaneous contact!
I wouldn't have said that matters in office installations. With 3 phase, it's all about perception of moving or rotating machine parts. In offices it's 'flicker' problems and frequency modulation may come into play.Lighting used to be spread across phases to lessen the stroboscopic effect
I know, its mainly done in factories where there is moving machinery like lathes etc etc,I wouldn't have said that matters in office installations. With 3 phase, it's all about perception of moving or rotating machine parts. In offices it's 'flicker' problems and frequency modulation may come into play.
But you can only plug one plug into 1 socket at a time, it's not as if you can play a monitor into 2 separate sockets at once and somehow put 400v through it. Is be very interested to hear a reg number also unless there's a hoover out there with 2 plugs hanging out of it I wouldn't worrySocket 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.
