Dual supply isolator and EDF

[mechelec]

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

The cut outs are supplied screwed to the chipboard backboard which is cut to fit at an angle. The newer ones are on a DMC/ fibreglass type backboard.

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.

It'll be like this once I take the link out down the bottom.

This is how I would do it. The back feed MCB as close to the CU as possible.
I don’t know how long the cable is to the PV unit. But it’s unprotected no matter what with your method.

Sorry to be a wet blanket. But even though I know little of PV systems, I do know about protection systems.

Ok well, me too, I don't know much about PV either.. and I don't think I will installing the future PV system in this house either unless I spend a shed load of money and do the quals and pay more to elecsa. however I thought it best to provide the simplest solution for the pv bod. Buying a PV ready board was too much and over the top because the PV was best added later down the road. I saw a diagram in the wylex pv book, put the tails in to the loft and installed the switch. This is that diagram left side.
