Shock protection on luminaries

I know that other standards sometimes have different ideas about shock protection to BS 7671 (e.g. BC and ES lampholders having bare live parts). Does anyone here know what the requirements for shock protection (when basic insulation fails) for domestic wall lights - specifically the type supplied with a flex, in-line switch and plug (i.e. expected to be in-reach). I'm not sure which product standard would apply. My natural reaction was to expect them to be either earthed or marked as double insulated - but are there any other options allowed by the product standard?

As you might guess, I've been asked to fit one and it doesn't look at all right to me - steel fixing bracket seems to be exposed to wiring with just basic insulation at the back of the fitting, and is then in direct metallic contact with the dome nuts holding it all together at the front.

I didn't much like the idea that it was sold as retail but supplies as a kit of parts - flex had plug and switch fitted, but supplied with bare ends to connect to the fitting - nasty if a little one got hold of it and tried to plug it in... but that's a different issue.

  • Thanks Z - yes the elbow was the main concern (the stem can also be rotated to point the light in the desired direction, which will twist the internal wiring to the connector). Also it's supplied with an in-line switch in the flex that's intended to hang just below the fitting and the self-assembly instructions make no mention of using the supplied cable tie to create a cord grip - so some movement on that end seems plausible to be too.

    I'd imagine that these days, most things should be either Class I, Class II or Class III -  I think all the other fittings I've come across have been, - but I wanted to check what the relevant standard said. This doesn't seem to meet anything and isn't marked anything other then "CE". Hopefully there shouldn't be too many like this one out there...
