Dedicated AC circuit?

[saint]

Hi
We need some advice on the following.......

A potential new client has a hefty SWA cable across his field supplying five 6A caravan hook ups. Ideally he would like us to extend it over to his barn (20M) for a 4kWp system therefore avoiding having to install a new cable under ground.

I have looked in Photovoltaics in buildings 2nd Ed. which says....

'An inverter supplied from a PV array must preferably be installed in a dedicated circuit which:
no current using equipment i connected, and
no provision is made for the connection of current using equipment, and
no socket outlets are permitted.'

But it says 'preferably' !!!????

So does it need to be a dedicated circuit or not? Not very clear wording!
Anyone used a non dedicated circuit before?

You can still have a dedicated circuit for the pv provided you have a local mcb. Even though the distribution circuit across the field is shared, the inverter itself would be on a dedicated circuit. There is a relevant phrase in MIS3002 also that makes sharing the circuit across the field arguably outside MCS rules. However MIS3002 goes beyond 7671 requirements for no obvious good reason.

ok that seems to solve the problem.
