wiring a bayoent light fitting to wire and plug

[joehowes]

Basically Im trying to make a lamp;

I have a bayonet light fitting, a wire and a plug. Is it possible to wire the bayonet light fitting to one end of the wire with a plug the other end. The light fitting has a switch to turn it on and off.

I have included photos so you can see what im working with. Also, wiring the light fitting, is it live and neutral wires to the outer connection, earth in the middle?

Thanks for any help or advice (even if it is... get someone that knows what they are doing to do it!)

Yes it can be done, are the connections on the fitting marked up?
The earth core goes in to the central terminal on fitting
The neutral (blue on flex) goes to neutral terminal.
The live (brown on flex to) goes to live terminal.
The plug would only require a 3A fuse.

That is just a standard bayonet lampholder, wiring is L&N to the outer terminals and E to the centre one.
On these, it is absolutely essential that NO bare copper is exposed outside of the terminal hole.

The black plastic component screwed into the end of the brass fitting is a strain relief to prevent the flex being pulled out of the holder.

So yes - you can wire that to a plug (with 3A fuse) - however what is it actually for?

thank you for the quick reply, as far as i can tell on the fitting the connections are not marked up...

Does that mean that it doesnt matter which way round the L&N to the outer terminals go? Also, i can see the strain relief.

The idea, i stole it from a bar, is a lab stand light holder, basically the light is held by the stand, socket and light one end of the wire and plug the other.

thanks for the reply!

If the terminals are not marked, follow flameport's instructions.
The plug will require a 3A fuse, so if it has a 13A in it, replace it.

Doesn't matter, since the lamp (light bulb) will fit in either way round.
The important thing is the centre terminal MUST be connected to earth, and therefore a 3 core flex must be used.

If it is supported on a stand, will be fine.

The reason for asking is that style of lampholder is usually screwed onto a base to make a table lamp, and if it has a strain releif it would normally be hung up by the flex, in which case you would generally use an unswitched type.

thank you for the very informative replys, yes the light will be supported by a stand and used as a desk or table lamp, meaning the switch is accessible.
