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.

    Well, in much of the world the conduit or trunking would only be earthed when serving as the main CPC.  However, in our double fault to danger world,  I agree, we should earth it, and perhaps these lights should be too, or the choc block sleeved. 

    It is only potentially dangerous, in that a single fault as you describe,  could expose a dangerous voltage without relief from ADS,  rather than dangerous now, which would be if it was actually live.

    Some makers of lights seem to make both class 1 and class 2 fittings on the same production line, and the only difference is the sticker, and if there is a screw or hole for an earth lug or not, I'd not read too much into it.
