I've ordered a metalclad FCU box from Toolstation, in order to hard-wire in a wall-mounted heater for my workshop (for anybody who looked at that post, I went for a fan-heater in the end!).
This is the one I bought
- this will connects via 20mm PVC conduit to the workshop wiring.
Just went to wire it up today and realised the deliberate mistake - the faceplate I've bought doesn't include a flex outlet. Bollocks (I got wrong-footed while ordering it, because Toolstation don't actually carry such an item in their metalclad range and I picked the wrong item when scrolling down the screen).
So I'm just wondering - is there a way I can run a flex out of the side or bottom of this box safely and legally? I do have some grommet like this:
I know there are suitable FCUs with flex outlets available elsewhere, but would be a bit of a PITA to obtain, and in any case I'd much rather have the flex to the heater emerge from the side of the box, rather then the front...
