I need to run 10mm cable, externally, from my upstairs bathroom to my Consumer Unit. I've always used rigid conduit in the past, however Flexi would make this job much easier. So, a couple of questions; Can I run Flexi outside? Plastic? Or Steel coated? Thanks.
The answer you are looking for is yes you can. Plastic is fine provided impact unlikely. Support with saddles.
10mm inside flexible conduit, not the best design, as Lec says, split concentric Oh yeah new circuit as well so its notifyable and warrants an EIC for regulations
