The bungalow was built late 80s, the cable length is about 24 ft run in the loft not under insulation. It has a 4way cartridge type CU, but the circuit concerned is coming from its own 1 way CU fitted above the main CU also with a cartridge fuse.
Thanks PB
I could have the 1 way unit replaced...
I have a 6mm shower circuit on a 30 amp fuse that is and will be no longer used, can i use this to fit 2 switched FCUs outside the bathroom that will run to 2 flex outlets in the bathroom for a 1KW a wall heater AND a 500 Watt towel heater.
Thanks PB
