I'm putting a wireless controller outside. Coming off a spare mcb on protected side. Using 4mm to an isolator then above damp course to outside wiska box to terminate to 4mm swa. My question is I'll be using the earth glands to connect the armour to the cpc but with these attached can you still connect conduit? It's more for cosmetic reasons as I don't like the look of swa running down a wall. Will a wiska aperture allow the gland unit and conduit nut to fit togther?
