Hi all

I've got a couple of wooden wall lights... I've just had them off the wall and I see that they are not earthed.

There is an earth on the lights. And there is an earth on the mains feed. So I'm presuming that it would be a good idea to connect them. But at the same time I'm wondering why they weren't connected before.

So in case I'm missing anything, I thought I'd best check with you before guys...

Cheers

If the bulb holder, the actual casing that the bulb fits into, is metal - i.e. you can touch metal - it should be earthed, it will have a tiny screw terminal near the base of it.

If the bulb holder is "plastic", all metal parts are concealed, it doesn't need an earth.

(Of course the innards that hold the bulb itself contains metal parts, but you can't touch these in normal use. This does not include removing the bulb and sticking your finger in the top when it's switched on!)

I'm pretty sure the bulb holder is plastic...

You're right. We've no internet at the house apart from very slow 3g on a phone on one square inch in one windowsill in the house! So we photo takes quite a few steps but I'll get down to it!

As it already has an earth lead, why not connect it anyway? The bulb holder itself is "plastic" (those wall lamp fittings look like they're bakelite, and so at least fifty years old!). But the fitting has a tab for earth, so give it one, no harm done.

Ok, great, I'll connect the earth. Just wanted to check for sure that I could cause a problem by doing that, especially in light of the fact that they hadn't done it previously.

Bakelite? Which part?

Cheers

OK, sorry, looking at pictures again they are wooden. Still pretty old, though!

No worries. Yeah, I thought they were old but then saw they have blue/brown. Guess they might have been rewired...

Thanks for all the help.

Did anyone see 'Money for nothing' today where they turned an old Woden vice into a wall light (what a waste)
The 'electrician' was shown wiring it using 2 core cable but it strangely ended up as 3 core woven when completed.

@ someone-else. Just received your report by pigeon. Disagree. It's an earthing question not a lighting question. Staying here for now unless another Mod disagrees.
