Due to not wanting to attempt to lift a tarmac path, I was forced to route the cable to my garden shed overhead. The distance from the house to the shed is only slightly more than 4 metres, so I simply ran a piece of SWA from the house to the shed, on a piece of catenary wire.
I installed a 32amp MCB in the main consumer unit, then ran a short length of 10mm twin and earth to an adaptable box in the roof space, from their I simply used 3 core SWA cable, running straight into the shed.
At the end of the SWA, I installed a standard metal 8 way consumer unit. In the consumer unit, there was a standard isolator, and three RCBO's, supplying the sockets in the shed, the lights in the shed, and another for the weatherproof socket on the outside of the shed.
All the sockets and light switches in the shed were metal-clad, and the light was a 7 foot Fitzgerald Anti-Corrosive fitting.
Cabling was run in PVC conduit, simply because it looked nicer and more professional than twin and earth, and that it was easier to use than metal conduit.
Mike, we tend to use catenary wire, but sometimes other methods are used.
Here are some of the accessories that are used..
