I’m planning a 30m SWA cable run to a detached outbuilding. I’ve calculated 4mm2 cores are sufficient (2.5% voltage drop at 4kW so I can run a small heater).
A small consumer unit will be installed probably 2 circuits (lighting and one or two sockets).
I already have a conduit buried and don’t want to pull the cable more than once I like the idea of redundancy but am not sure if it achieves anything… realistically how many cores?
