Electrician Jobs Anyone know what these 3 pin sockets are?

[Felicity]

Hello all
We have moved into a 1960s house, grade 2 listed. electrical wiring modernised by previous owners. These 3 pin sockets still wired in (pic attached): they are NOT the standard 5amp as the top pin is much smaller than the bottom pin. My electrician has no idea what they are for. We would really like to use them for lighting, as per architect original plans (but does not say what type of fitting). Any info most welcome - has someone seen before and know if we can use/rewire? I have internet searched myself to distraction and even looked at online library of plugs and sockets.....! Thanks, Felicity

I don't think the top pin is smaller it is just that the lower two are shrouded. Does a 5A plug fit it.

 

[Felicity]

thanks for taking the time to reply. no a 5amp plug doesnt fit: the space between the upper and lower pin is much narrower than a modern 5amp

 

[westward10]

They maybe a 2A as you can see from my pic they are tiny.

Seem to recall 2amp sockets?

Dooh

A picture of the rear of the connector/connectors would be helpful. If they're powered up, you might need your electrician to help with this.

Edit: agree, they might be 2A connectors.

 

[Felicity]

they are wired to the wall and scared of electrocuting myself so will need an electrician to take a look. the 2amp looks more like it..

Is that box a fixture or free standing , does it look like it had a specific purpose - like a transformer of some sort

To me it has the look of an old Bulgin socket for a Bulgin 2.5A plug.

If you contact Bulgin:

Circular Power Connectors - Standard Series | Bulgin - http://www.bulgin.com/products/circular-power-connectors/standard.html

using their email contact form they may be able to help. I cannot find a telephone number for you to try. Their HQ is in Cambridge so you could try directory enquiries for a number.

Here are some images of what may be the right plug:

or an older version of this plug without the shrouds:

If you read the thread, the holes are too close together for a 5A plug, let alone a 15A one.

Ultimately, if the wiring is OK, you could just get the plates modified (or new plates) to accept whatever socket is required.
