Wiring a lamp - advice please

[RickJ]

Will it still earth the pipework because the lampholder is made of plastic?

Thanks Ruston.

I like what you've done, great idea.
I think you may need a pressure gauge that is rated up to 30bar though as it is electricity and safety is always first!
Post a photo of the finished product.
Did you have bits lying around or did you buy it all, what's the bill so far?

It looks great, nice job

The pressure gauge is only for show and isn't connected to anything. I'll certainly post pictures of the finished article. Got more elaborate ones planned.

All new parts. Probably runs to about £50+, especially allowing for my adventures in wiring

In the future, rather than use crimps I would go for solder splice, not a hope in hell of those coming undone.

I like the idea of the lamp!!!

Thanks for the great feedback guys.

Just to clarify. I'm rewiring so that I don't need to splice inside the lamp.

The lamp fitting has an earth connection. The lamp fitting is plastic. Do we think I'm best also running an earth crimp/lug to the pipework or will the earth in the lampholder suffice?

What if I was to use a metal lampholder?

I'm also planning on making ones with multiple bulps wired parallel. Will Wago connectors do the job ok?

I think that just about covers it...for now

Thank you, you've all been so helpful.

Earthing the lamp holder or threaded part of the lamp holder like you have will earth the pipework assuming it mates to the correct thread so no need to fit another earth.

Come on @Rpa07 you should know that!

Looks good...

Heatproof cable is just that really. As @westward10 said if the lampholder is screwed to the metal work then maybe a lug is not needed. However currently you are not using a metal lampholder thus the idea of running an earth from the lampholder to the body of the lamp. And as stated earlier, you may find difficulty in matching threads from lampholder to pipe. While I like the crimps @Strima shows, it is a principle the more connections the more potential faults. Hence the suggestion to replace the cable get a brass lampholder with switch, heatproof cable,

His plastic lamp holder has a metal threaded collar with an earth terminal, looks quite good.

Just for possible future reference, would I just run an earth wire from the earth terminal of the lamp holder to a crimp lug on the body? If I was to do something that way.
