Changing a bayonet fitting on a lamp

[BertieButton]

I need to change a fitting to a lamp but the instructions do not tell me where to place the three coloured wires.The old fitting had 3 clear areas for the wires but this new fitting only has two! What colour goes where?

[BertieButton]

I've got it! I can't put a plastic holder on a three wire lead! Back to Homebase then!!!!

A plastic bulb holder only needs two wires - the brown and the blue. And it doesn't matter which way round they're connected. The earth wire - green and yellow, can be cut back. It's a metal bulb holder that must be earthed by connecting the green and yellow wire to the holder's outer casing. No need to go back to Homebase.

I wouldn't recommend using the 2 wire lampholder if the lamp the lampholder is attached to has a metal body. If you cut back the green/yellow earth wire you could end up with no earth at all on the lamp. The lamp could then become live in the event of a fault.

Go back to Homebase.

As Heathy has said, a plastic holder does not need an earth.

BUT ........... if the lamp body is metal, then connect the earth to that.

Though I'd really hope if the body is metal it has a separate earth point direct to the body!

Buzz it out with a multimeter to check.

The pink wire goes to connection 1.
The orange wire goes to connection 2.
And the white wire goes to connection 3.

Quite, OG. Good luck with that Bertie. If you've got a white wire, a pink wire, and an orange wire, you're not in the UK or you're colour blind!

Yes, I should have mentioned earthing a metal lamp body when there's an earthing point on it.

Thank-you all! I've gone with a metal fitting as was previously on it. Old_ Geezer, PLEASE stay away from all this new fangled "electrocity" stuff, I fear for your safety!!

If you don't already know the answer with confidence they you should not be even considering undertaking this task.
