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.

    The connector block in Class II fitting is usually fixed and/or shrouded so that conductors with only basic insulation (including the installation side ones) cannot come into contact with the metalwork. Sounds like the installation might have been botched with this one (or possibly incorrectly manufactured). When done correctly Class II should be at least as safe, if not safer, than Class I (no risk of ADS being compromised by broken c.p.c.s, bad earthing or sticky RCDs).
