Dual supply isolator and EDF

[rustynails]

No real reason for them not to use that switch but I have to question why you have used a 4 pole switch and what you intend to wire to the other two poles?
Normal PV insulations are simply connected to a spare way in the consumer unit either via an MCB or RCBO and they feed in back through the meter so not sure why you would need a second set of tails

It won't be a feed in system, it'll be off grid.

How come the cut-out has had to be bodged on to a bit of chipboard screwed on at a 'jaunty' angle? Did someone mismeasure somewhere? Daz

I think they've started doing this as standard. YEDL have done it on a couple of jobs last year and with yours that makes three, so therefore it MUST be the new trend. Looks sh1*e

I reckon the dude who come to fit the meter,got a touch of the UKIPs'....too many poles for his liking...

Unless i'm mistaken, (it is early here lol!!) by the look of it, you have used one pole of each of what will be 2 DP switches. So i'd move those tails to accommodate the left two cable entries on that dual isolator, the right two entries will then be for your future PV system.

So what are the extra two poles on the switch for?

Surely you're not expecting the supplier to split their supply into two feeds just to accommodate your 4 pole switch? What's the point?

The switch has entries NNLL from left to right with busbar links inside. I actually think I've left a link in between incoming NN which should be moved to the outgoing NN.

That's fair enough then!! Seems a strange way to to link the isolator out, confusing even!! lol!!

Fair enough. Just looked up the manufacturer's data on these; obviously designed for PV installation.

I'd leave the links on the incoming side. Otherwise, no point in having a 4 pole switch.

I think you're right. If you don't there is still a link between the two systems with the switch in the off position, not good for DNO personnels health.

They have been doing that in Milton Keynes for donkey's, plenty of external meter boxes there.
