Wiring for E27 batten lamp 100w halogen

[dgratton]

I have an E27 batten lamp holder for a 100w halogen bulb. I want to attach an electrical wire to it with a plug on the end. The idea being that I plug it in to use it. The holder has 3 holes at the back for the wiring to be attached. My question is two fold: what size wire do I use (ie 1.5mm t&w, or 1.0mm or something else) and what are the 3 holes for (ie which is live, where does the earth go - if earth is used as there is no mark as to which is which, etc.
Thanks for your help in anticipation

If you're putting a plug on the end you must use flex- T & E is not suitable. Which wire goes where- if the terminals on the batten holder aren't marked then throw it away and buy one manufactured to the appropriate standards (which will be marked) unless you can determine (by inspection and meter) which terminal does what. Clue- LIVE would usually connect to the tip of the lamp base, NEUTRAL to the thread of the lamp base, EARTH any extraneous metalwork on the batten holder - if the batten holder is plastic then the terminal may not be connected to anything.

A batten lamp holder may not be suitable for this application. It would need to have a suitable cable restraint, and not rely on being mounted to provide adequate isolation against the connection points for the wires.

If it's a batten fitting and not a metal, I suspect the third hole is for 'live loop', just like a ceiling rose.
Caveats apply, I have sloping shoulders and haven't seen it so don't quote me.

The third terminal could be used to park an earth wire though.

Will you screw this down? Halogens are not suitable to be used as a lead light

Yes totally agree.

Batten lamp holders are not suitable to be used as a lead light.

Yes totally agree, I meant to mention that earlier.

Thanks for the response. This is the holder. I will fix the lead secure so that only the plug can push into the socket of the extension lead. It is for my shed and will be used very infrequently. From what is said the live will go to the middle and no earth necessary. Do I still need to use flex?

 

[DetlefSchmitz]

Yes

"Do I still need to use flex?"
Yes. As you are using a plug on the end of a cable you have to use a flex cable (T&E cable is never to be used with a plug).

And the flex has be three core (ie have an Earth lead that is connected in the plug and terminated at the Light Batton).
This way the cable is protected with a working earth all the way to the light batton.

For workshop I would use this 3 core 0.75mm2 flex for lighting use:

Thanks for the response. The only query that I have now is where do I attach the earth wire at the batten light end as it is made of plastic. Do I use the third hole that someone suggested could act for a 'loop' or can I attach the earth to the screw that holds the batten light to the wooden roof joist. Thanks

@dgratton You do realise that halogen lamps of all types are being discontinued?
Read and weep
Thoughts of a different solution may be in order.

 

[SFK]

If that connector is not connected to anything else, then yes.
Normally I sleeve it and terminate in an insulated connector (piece of choc-block).

As Taylor says, halogen bulbs are being discontinued.
But you could put in a LED E27 bulb:

And I know it is Florescent (rather than LED), but I would recommend this as it is cheap and emits a massive 1320lm for its 20W of power.(teh down side is that it takes a few seconds to get up to full brightness).
