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.

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

    Sometimes Class II fittings have a specific advantage over earthed ones - e.g. where the fitting is outside the equipotential zone, or were normal dry skin conditions really don't apply (e.g. lights for zone 1 of swimming pools) - so in such (rare) cases there would be a disadvantage. Normally though, where Class I would be acceptable anyway, it unlikely to make any difference I would have thought.
