Hi

I am installing an outside floodlight, to be fixed on the wall of my house.
I plan to run about 5m of twin core and earth cable from the garage,
connecting via a fused connection unit, and clip the cable to the nearest
wall. Is it ok (Wiring Regs) to do this, or do I need to enclose it within a
plastic conduit? I seem to remember reading that plastic conduit was not
suitable in low temperatures. Cable run is mostly horizontal, but with quite
a lot of bends, so would be easier without conduit.

TIA

Joe
