Whilst looking at ronning a power supply for a sauna heater (Thanks for the answer adam151). I lift the floorboards to find my hall lighting has 6 low voltage down lights (each with its own transformer) on one switch but the lights are wired in series not parallel terminating at the last light...
advice required!
I intend to fit a sauna which will cover an existing twin socket (with spur off). Am I ok to replace this socket with a junction box (keeping the spur off) and extend the ring main to a new socket with a spur off to the 6kw sauna heater?
