One for our resident certified electrical installers ... I want to add a spur to feed a wall-mounted smart heating controller, which has a PSU as part of its wall-mount kit. I don't want to have a fused spur plate on the wall so am planning on putting an in-line fuseholder in the back-box for the wall-mount kit. I don't have any concerns about whether this is safe, but I can't decide whether it meets the regs or needs any specific labelling. Can anyone here provide the answer?
FYI it's an Evohome system with an ATF600 wall-mount kit.
