Understand the "pipe only on the drops" method, but I figure that while I'm installing that I might as well run the whole lot in conduit for what little extra work is involved on the typical install. (Could use some extra ventilation from using the PVC cement in some places though... [Linked Image] ).

I like to run a 30A sub-feed to a garage or workshop, unless it's just a small shed, owner on a very tight budget, long run of feeder which could be substantially cheaper on a 20A circuit, etc. Even if the extra capacity isn't needed now, it might be in the future, and as I always try to point out, upgrading to a 30A feed later is going to be much more expensive than the extra it will cost at the outset.

Lyle raises some interesting questions regarding earthing arrangements. About 90% of the homes in my immediate area are TT with a single main RCD. I really don't like taking the sub-feed off the existing panel if I can help it, as I'm not keen on the idea of an earth fault on the garage/workshop taking out power to the whole house, but if space and/or cost constraints mean I can't tap and fit a separate RCD/MCB combination or RCBO for the feed, there's not much choice. (It's no secret around ECN that I don't much care for TT systems anyway, right? [Linked Image] )

Just a small question Paul, how would an overhead cable be run to a shed in the UK?
Yep, catenary wire, although I haven't done one of those for a long time now.

the light was a 7 foot Fitzgerald Anti-Corrosive fitting.
My regular supplier carries Fitzgerald, but not the anti-corrosive types, for some reason. I just recently installed a couple of 6 ft. Dexra anti-corrosives, about £22 plus VAT each as I recall, excluding tubes.
