Wiring lampholders, earthing question

[jim witherspoon]

Hi, I have been looking at using these fittings for some lamps I was planning. Could anyone advise if they should be earthed? Although the outer shell is metal the bulbholder is ceramic and CE marked but they dont appear to have an earth tag. Would an earth tag attached to the metal stirrup at the top of the ceramic fit the bill,Thanks, Jim

It's metal, not designed to be double insulated, so the answer is yes.

The reason is simply that it's not impossible that one of the connections could become loose and touch the metal outer shell.

If you look at the fitting, the steel U shaped riser from the ceramic holder has a screw hole on one side of the riser. I would guess, that is the point at which the earth should be connected, taking care not to damage the conductors with the screw itself.

I was looking at these the other day whilst window shopping on eBay! There are some pretty lampholders out there that you could create an interesting lighting fitting with. There are pend and roses with 5 outlets that with five flexes and the lampholders would create something quite dramatic! Or am I being soft?

I spotted these on Banggood.com along with many variations and similar fittings. Its always a challenge to see how they could fit in to UK standards! Their Edison Bulbs are amazing value.... I was amazed my first batch arrived from China in one piece.
