Hi All, I have a question about wiring up garden shed for power.
I want to fit a metal Garage consumer unit to power 2 double sockets a 100W lighting circuit and the possibility of a 500w flood light.
The shed is to be fed by a armoured cable suspended from a catenary wire (methord 13).
Looking at the standard parts available, A 40A breaker in my main cu, feeding a 4mm armoured cable (41A) feeding the second consumer unit fitted with a 32A (30ma) RCD feeding a 20A MCB for the sockets and a 6A MCB for the lighting should be sufficient.
However when I look at the diversity of the load (600W/240)*1.8 for the lighting + 13A for the sockets I get a load of 17.5A. Is there a better set up than the one I have set out above ? Perhaps utilising a thinner cable ?
Any suggestion would be much appreciated.
