Correction - it will not conform to regulations if you neither use an electrician nor DIY it properly.I suspect that however which way I do this it will not conform to regulations unless I use an electrician.
Voltage drop.I do think it should be pretty darned safe though, how about if I use a plug in RCD adapter on the house socket?
Fault loop resistance.
Depth of buried cable.
Testing for continuity of protective conductors, insulation resistance, polarity, fault loop.
RCDs do not protect against overload. And as said, 2 in series won't mean that on trips before the other. If there's a problem in the cabin you could take out some or all of the house circuits. You could have to go back there to reset it. If you're in the house you might have to schlep out to the cabin to sort out a problem.This then would mean the cabin would trip if there was an issue in the cabin and the adapter would trip before I overloaded the house socket.
You should do some studying before trying to do electrical design work.

- http://www.tlc-direct.co.uk/Book/1.1.htm[/list]I suggest you get stuck into the last link right away - it won't give you design ideas, and unfortunately it doesn't refer to the current edition of the Wiring Regulations, but it's free, and will still give you a good grounding which you can augment with more up to date publications.
Its really a glorified shed so as long as I'm mindful of the dangers I'd like avoid too much legislation, its not a public building.
I don't think you're there yet.
