Metal Class 2 Wall Lights.

Zoomup

I was testing some chrome wall lights today for earthing. They were not earthed. I could not tell initially if they were Class 1 or 2. I took one off its stirrup wall bracket and had a look behind the base plate. A label inside confirmed that it was a Class 2 light fitting.

But, the choc blocks floating about in the metal circular base, and the metal wall bracket could theoretically liven up the fitting if a strand of conductor was left by the installer, and it touched the metal parts. This home has no R.C.D. protection at all.

There must be many such wall lights about.

    ietmgreen: Are there any real technical disadvantages to adding an earth connection?

    So someone's changing a light bulb - there's some sort of problem getting the new bulb in, so they stick a finger inside the bayonet holder to feel for any obstruction (because they know the light switch is off). The other hand is holding the metal light fitting. What would have been a tingle has now been upgraded to a fatal shock.

    That risk has to be weighed against the risk of the fitting itself becoming live if unearthed.
