Two single phases through one isolator?

[snowhead]

Why have you shown the neutral to MC2 being supplied from the supply side of the isolator?? Or am i still half asleep?? lol!!!

Both neutrals are from the load side, and I'm not half asleep.

I’ve just thought of a down side to using two phases. If there are any sequence connections between the two panels you could have say190V between two 110V systems. I’ve just used 110V as an example.

Is that the finished article?
Looks a bit pish to me,lots of badly routed cables in the control side of it and the cores don't even look numbered (that could just be the photo).
Like Tony I don't like the installation idea at all,although it does work and of course you need to please the customer.
I'd always use separate supplies,makes fault finding easier and just relying on an mcb for protection should you need to keep one live and one dead is not ideal.
Just thinking from a 3 am phonecall to say the plasma cutters not starting point of view,if I turned up at that panel with no numbered cores there'd be some expletives emanating from my mouth!!!!
Things would also get thrown about no doubt!!!!!

Yeah I agree with everything you say.

Not exactly a great design, but neutrals will need to pass through the RCBO and RCD
