I came across three downlights yesterday that had, in my opinion, been wired in way way the does not conform to the 17th edition.
If you look closely at the wiring going into the downlights connector before I rewired it, the internal cables are exposed. All the cables including the outer sheaf of the cble should be securely fixed into the downlights connector block with the use of the cable clamp.
Some downlights do not have enough room to fit two cables into its connector block. In this case I would use a heat resisting flex or sleeving for the cables coming out of the connector block of the downlight, and use a 'click' type connector designed for connecting downlights, to connect all the cables together. Doing this would ensure that all the cables are securely fitted and enclosed when they are in the ceiling space.
