I am wanting to install a double external socket in my garden to power a pond pump and some low voltage lighting. I have some 2.5mm armored cable and I'd like to run the cable to a fused control panel in my kitchen which has switches for kitchen appliances such as dishwasher, cooker hood and one of which is spare. This would enable me to isolate the power to the external socket using the switch. Can anyone see a problem with this? House is new build with RCD consumer unit
