Wiring For Outdoor Wall Lights

What do you want to know?

There is no preferable method.

It depends on the position of the items.
Supply, switch and lights.

I would recommend fitting a double pole switch ( Live and Neutral ) so that the lamps when OFF are fully isolated.

If only the Live is switched then if a lamp develops a fault Neutral to Earth ( damaged or moisture in the lamp ) an RCD protecting the circuit may trip even though the lamps are switched OFF
 
Many thanks again

I just wanted to know what is the best way to leave the cabling for the electrician, 2 separate cables or into one and then looping into the other.

There is an existing internal light in the garage ceiling which is controlled by an existing switch at the other end of the garage.

Thanks for your help

Many thanks all, and apologies EFLImpudence if I was testing your patience.


As suggested by securespark, I think I might go for the 2 separate cables to the switch.


Please could you confirm the following seems acceptable/correct?


Run a live cable from the existing garage ceiling rose to the switch,

Put the neutral from the existing ceiling rose into a separate terminal block/wago in the switch (stored in the backbox)


Put both the neutrals from the 2 new cables coming from the new outside lights to the terminal block/wago

Put both the lives from the 2 new cables coming from the new outside lights to the with terminal.

Maybe 1.0mm would be better then, with it being 2 seperate cables!


Thanks again
 
All the neutrals and earths together.
The live from the ceiling rose to the switch common.

The lives to the wall lights in L1.

And if you fit a DP switch, the incoming feed from the ceiling rose to the FEED side and the wall lights to the LOAD side. And earths together.
 
Sorry are double pole light switches common place, cant seem to find many on the internet?

Thanks

Screwfix have them.... click HERE
I presume that the confusion arises becasuse, although double-pole switches (usually at least 20A) are common, one would probably struggle to find any of them described as 'light switches'.

However, a double-pole switch is obviously a double-pole switch - and it doesn't know whether it is being used to switch a small lighting load or something much greater (like an immersion heater).

Kind Regards, John
 
Does this need anykind of trunking going through the brick wall? Or is it ok without?

Thanks
