    The cabling in my garage is all clipped directly to the walls and joists using plastic cable clips. I am going to run PVC conduit for all the cables to tidy it up and make it a bit safer. But in doing so, there are two places where the t&e currently passes through the brick wall - one feeds a PIR and the other feeds another light switch. In one instance, the cable is has been bent at a 90 degree angle as it passes into the wall. It emerges in the other side and goes directly into a PIR sensor. My question is, if the cable was inside a 20 mm pvc conduit, how can it be passed though a wall at 90 degrees? Bending the conduit will result in a radius that's too large that it will stick out..... is there a prescribed way to pass a cable through a solid wall at 90 degrees in conduit?

    You would tend to use a straight bit of pipe through the wall and some sort of round or square surface box mounted over the end, the cable bend being within that box

    The easy way is a 1 way conduit box with a hole in the back for the cable to pass through.
    The proper way is a 20mm hole in the back connected to another piece of conduit using a female adaptor, but that will require making the hole in the wall larger.

    However putting T&E into conduit is neither necessary or desirable, it won't make anything safer, and you are just making a pile of work for no reason.
    Unless this new conduit will be fixed with metal saddles, it won't comply with wiring regulations from January.

    It will do if he does it by midnight Dec 31st as regs are not retrospective.

    I was gonna use metal saddles too. It just looks a bit of a mess at the mo. It'll look better in conduit.
