Can anybody advise me on connecting some lights like these http://www.screwfix.com/app/sfd/cat/pro.jsp?cId=101031&ts=91986&id=44103. I have benn asked to quote for a job involving wiring 10 of these lights in 2 rows of 5 about 3 meters apart down each edge of the block paving.I was planning to run 2 lengths of SWA to each set of lights, but the fittings come with a IP68 rated connection box which is only suitable for connecting 3 core flex. I was considering connecting the SWA cable of into a larger IP65 adaptable box and connecting the inner cores into the smaller connection box supplied. The boxes will require positioning under the block paving on a bed of sand so they shouldnt be submerged in water and protected by an RCD. This job will be part P'd by myself but as I havn't done anything like this before any advice would be appreciated.
