I have some wiring in my garage (done by a sparky believe it or not...) where the wire is quite loose, just tacked to the wall with clips, and there are a few junction boxes as well as the usual switches etc.
I'd like to enclose the wiring in plastic conduit to make it neater and more protected, but I can't for the life of me see how the junctions would work! All the conduit junction boxes are just empty boxes, e.g. this one from Screwfix
Am I supposed to put a "normal" junction box inside of that? Or do conduit junction boxes exist somewhere that already have wiring blocks in?
Seems a stupid question but I can't found the answer anywhere!
