Sorry for the dumb question but I have no regs at home and am having a blank.
A friend has asked for me to run a cable to an outside shed for lighting and en-route go through a couple of adaptable boxed with flex outlets to run a couple of floodlights on the side of his house. The SWA will be clipped directly to the outside of his house and then along a wall to the shed. He hasn't chose any outside lights yet but I am going to allow for 1kW to be safe although I am trying to recommend energy efficient ones. In the shed will be 3 x 70w strip lights so I have a total load of around 1.2kW
From looking at some old notes I had worked out volt drop on 230v over 50m to be around 2.5% on a 1.5mm2 SWA. Is this correct and if so am I correct in thinking a circuit with lighting needs to be under 3%????
Sorry guys
