Outside light from twin socket spur

[kvfilms]

Hi guys,

Forgive me if this has already been answered in part, but I just want to have it clear in my mind before I blow the garage up... lol

currently have a 240v power supply to my garage, which feeds 2 standard strip lights (switched) as well as a standard twin socket.

I want to install a standard outside garden light, taking a feed from the twin socket.

Can someone please confirm that it is safe and possible to do so, before I go any further.


Cheers

It would be useful knowing a little more about the installation in your garage first. Where does the supply to your garage come from? This might help in identifying whether or not it is RCD protected and that the current installation is safe. We can then further advise on connecting an outdoor light.

Hi, Thanks for replying. The power supply originates from the main house supply, via the consumer Unit. There’s a separate fuse on the consumer unit solely for the supply to the garage - all of which was professionally installed.

I’m hoping to take a feed from the twin socket, with a 5amp fused switch spur in between the socket and the garden lantern.

There’s a RCD – 30mA 230v fuse on the Consumer Unit, which I know from experience cuts the power supply throughout the property, including the garage.

You are in good shape than. That new garden light, is it 230V or 12v, with a transformer that would be mounted inside?

There's things to look out for. You just cant go draping bits of flex around your garden if its mains voltage...

Hi, Thanks for getting back to me. There's no transformer, just following the instructions on the box, it's 230v I've been told that I need a 2.5mm twin & earth between the extisting socket (which will hopefully provide the power supply) and a fused 5amp switch and then 1.5mm twin & earth between the fused switch and the light fitting, which is of course on the outside of the wall.


Does that sound about right?

Yes, that sounds about right. The only thing I might suggest is using 1.5mm flex instead of T+E if the outdoor light is a floodlight. The flex will be more suitable for the cable gland on the light fitting on account of being round, and should be less succeptable to damage from the elements.

Hi, I'm pleased to say that after only about 30min (baring in mind it was my first attempt) that all is well and working, quite easy really, however, since I already had the 1.5mm T+E I used that as none of the T &E is exposed - it goes through the wall and out the other side directly into the back of the light fitting, which is mounted on the wall - it's a standard 60w garden/ porch lantern.


Thanks again

Good to hear you got it sorted, HTH
