Copper Pipe Lamp Earthing

[electronurd]

Hi all,

Hopefully someone can help me. I am going to undertake a small project for my home which will be a copper pipe lamp for the living room.

I bought a lampholder and wire and have a few questions before I start.

The lamp holder is metal with a ceramic insert (see pictures). I have also found a nice youtube video which shows the exact same one here:

There appears no earth terminal on the holder itself just a small hole. I am also aware that as the lamp is made of copper that will need to be earthed accordingly. Here is something similar I plan to create: Copper Pipe Retro Industrial Chic Table Lamp - https://www.etsy.com/uk/listing/493455097/copper-pipe-retro-industrial-chic-table?ga_order=most_relevant&ga_search_type=all&ga_view_type=gallery&ga_search_query=copper%20pipe%20lamp&ref=sr_gallery_13

My question is how would i go about earthing the holder and the pipe itself. Would i need to unsheath the earth cable all the way through the lamp to ensure the whole lamp is earthed?

Thanks

Soldering is a very low resistance joint (if done properly). That's how a heck of a lot of electrical connections are made!!

Oh well i'll be soldering the copper pipe too. So you would solder the earth directly to the pipe? what about the bulb holder?

Difficult to say without seeing exactly what you are doing. The main thing to remember is that any metal part needs to be connected to earth via a mechanically and electrically sound method. Safety is paramount - I know it's in your own home, but it could still pose a risk.

That definitely needs an earth and it looks like it should go on the bridge section which fits the lamp holder

Do you mean the thread that is secured by the bolt? see video in my original post.

oh yeah i understand and wouldn't attempt anything without advice first. It just difficult to know where and what I need to be earthing and how.

No the threaded part fits to a small bridge section, this then attaches the lamp holder. There is a hole in one side of the bridge and this is almost certainly where the earth goes.

ah yes I have seen this. So would i solder the earth to that and then would i need to solder earth to the copper too to ensure that is grounded?

No you won't be able to solder to that bridge section. If it is threaded it needs a screw and no earth is required to the pipework as the lamp holder will earth it. The earth connection to the bridge section should not be a screw and nut it needs a thread.

Thanks. Food for thought. I'll try and get a good understanding of that and reply if i'm stuck cheers.
