Many thanks for your replies.
So the cable size may be smaller than the size of the circuit ?
The basis I have used for the cable size of 1mm is that it connects a single light fitting ... even if I fitted 100w halogen bulbs it would be less than 0.4 A.
Does that sound sensisble...
Hi,
I am planning on adding a couple of extra lights to an existing 1.5mm radial light circuit. in my enthusiasm I bought some 1.5mm twin and earth and some junction boxes and was quite happy.
But, I bought a 1 mm heat resistant 3 core cable to run form the junction boxes to the light...
