sorry strima, I was using Doncaster cables calculator having no book to hand.

Thanks for the replies. All seem to be agreeing it's a caravan rather than a socket outlet, so that helps.

No plans to randomly order up the SWA cable from an internet forum comment, but thanks, will wait until I've spoken with someone willing to do the design for me (No PM's so far). The groundworker is going to open up trenches week of 16th October and hoping to close up that Friday, so there should be plenty of time. If not I can keep the sheep out and leave it open another week. I'm doing the plumbing so it won't be moving very quickly.

I have learned plenty from this forum, just to identify what there is. There is a Henley service connector block after the meters, before the first consumer unit, but no isolator other than the DSO's fuse, so adding another CU at that level would need some coordination. It's easier to run cables from the second CU as the outbuilding is partly in the right direction, and unplastered, and it follows my runs for the water. But the T+E between may not be sufficient - looks like good cooker cable to me.

I tried to draw a circuit diagram of what is happening on the DSO side at this house and it looks like a pretty weird setup. There is a manual ticking VENNER ERO28P timeswitch providing a small-diameter signalling input to the modern "Multi-rate single phase watt house meter". But there also looks to be what I can only guess is a switched live from same VENNER switch that is in parallel to the modern meter and joins at the henley block (or maybe I misunderstand the purpose of that cable). I'm no expert but I don't see how they could measure any kwhs when that wire is switched live, guess that's a DSO problem! I'll send a pic if interested...

That timeswitch will be sending a signal to the meter to tell it when the off peak period of the economy 7 supply is.

Presumably the house has night storage heaters?

It's Oil fired now, they might well have gone in the 1996 rewire.

Found someone reasonably local to come out and look at it on Thursday. Thanks for looking.
