Hi,
We have a retaining wall in the garden on the edge of our patio. Our electrician has run some armoured cable behind the wall, coming through at regular intervals for the lights (the cable will eventually be buried by the earth the wall is holding back).
The trouble is, the cable he has used seems to be really restricting the choice of lights we can use.
The cable is stamped with 600/1000v BS5467 h nexans 3x1.5. After some Googling, I found the following specification for the cable:
CU/XLPE/SWA/PVC BS 5467 3x1,5 mm2 - Nexans - https://www.nexans.co.uk/eservice/UK-en_GB/navigateproduct_540168747/CU_XLPE_SWA_PVC_BS_5467_3x1_5_mm2.html#
This says the cable has an outer diameter of 12mm, and as we need ingress/egress for 2 cables, I am guessing that the spigot is going to have to be 24mm (possibly larger?).
However, I'm being told we need to allow for 80mm, and as a result the proposed light fitting is too industrial (looks like a light on a shower block in a camp-site - not quite the look we're going for). So my questions are:
- do we really need an 80mm spigot for 2nox12mm cables?
- if not, what's the minimum size spigot we should be looking for on the fitting?
- is there any way to use an external, IP65, armoured junction box on the back of the wall (which will eventually be underground) to reduce the size of the cables required to go in/out of the light fitting?
- finally, can anyone recommend any suppliers of light fittings for such a setup?
Thanks in advance!
