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.

    In doubtful cases I would consider adding an earth connection if reasonably practical. I appreciate that some people are opposed to so doing, and state that adding an earth is “altering the design” or “voiding the CE marking”

     

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

     

    Not so far as I am aware in the case of a light fitting. Adding an earth to complex equipment might have undesirable results WRT earth loops, data corruption, or interference with audio or video signals. But fine for a light fitting.
