Currently using extension cables to bring power to one corner of my computer shop work (in a spare bedroom) which is not ideal for many reasons.
Now assuming it is not an end of spur (which it shouldn't be as it is in a middle room but I shall not assume) I could simply take a spur of that.
However the existing socket only has around 3 amps of load on it, I use it for a laptop so the easiest way would be to simply put the new extension on a plug but it is not ideal.
So my questions are:-
1) How do I calculate the correct cable thickness? I assume there must be some formula which takes cable length and thickness of the conductors. The cable will put into plastic trunking.
2) Is wiring it up as extension lead with flex completely against the rules providing the correct thickness flex is used?
The new socket will typically have around 10 amps load at the most, but how many sockets could I have of one spur? I was think of installing two doubles, to give me a 26amp capacity (though in reality it would only be ten amps).
3) Do any new sockets need RCD protection?
4) How do I test the existing socket is not already a spur?
In terms of test equipment I have an oscilloscope/multimeter and a very basic socket tester, but I have no proper test equipment.
Thanks in advance.
