I've built a new pergola to replace the old one that was attached to the back of our garage. The new one is still attached to the garage and I would like to know if it's possible to use the garage lighting circuit to supply a round 40w(ish) bulkhead in the middle of the pergola and a low wattage (120w) halogen floodlight on the end of the pergola to give a bit of illumination to the garden if needed.
The garage has it's own consumer unity with an RCD, a 16a ring and 6a lighting circuit that's currently using 4 strip-lights totalling less than 800w on it.
I was planning on using 1.5mm t+e clipped through the wall around 12-1500mm up from the floor and straight into a 2G IP55 switch and then on to the respective light from each side of the switch using 1.5 t+e.
Is this practical? Do I need to protect the cable using conduit?
Or as the wiring is external, does it need to be 1.5mm SWA?
Thanks in advance
