Will it be OK to do the following after demolishing a porch. At moment I have a 2.5mm 3 core cable coming from the consumer unit on its own trip switch which used to feed the porch and shed. I want to attach an IP66 rated junction box outside and place this cable into it. Then feed an IP66 rated double socket outside and the electrics to the shed all from the junction box using 2.5mm flat cable. Also feed an outside security light from the junction box.
