cable size for lights

In general either (relevant to suitability)

Personally I fit 1.5 for lighting

1.0mm T&E Current carrying capacity.
16A clipped direct / embedded in plaster
12A in conduit in an insulated wall

Also consider voltage drop.
If you are using a 6A circuit breaker and your design current is as high as 6A (expect it would be lower for your installation) you would have a voltage drop of 9V at the end of a 32m length of 1.0 mm cable. (drop must be <9.2v)

Therefore, 1.0 is fine for a 6A cct with a length <32m.

Yes mate all nice and fancy..however some people do not like using bell wire with a CPC. Get some beef in and use 1.5mm..u know it makes sense.

 

Dont be silly JP
Why not run it all in 6mm then - what sense is there in that.

Use the appropriate cable for the job.
Look at the design load, protective device, and cable length.

If someone can't be bothered then yes - run it all oversized.

 

Ding ****..is that the Avon Lady dear?..no its ok mum.. its only SparknPlumb.

1.0 why oversize when there is no need.Also a darn sight easier to terminate

Could not agree more, why make life difficult

 

1.5 all the way for me these days.
People like to fit squillions of spots these days and often dont tell you till half way through the job.

For several reasons I normaly have both on the van, and use them depending upon how I feel and which way the winds blowing.

 

What about using 1.5 for the loop and 1.0 for the switch drops?

 

Yes... why not

 

We wouldnt have to mark the cables.
Excellent!

 

And the 1.0mm could be purchased in Brown/Brown

Hmmmmmm...

 

Do you like a bit of brown then Peng? , I agree with JP. as usual, 1.5mm.

It was a 'phase'

 

Aye tis funny however..usual on hand cable for site was..8 x 1.5mm
8 x 2.5mm
2 x 6.0mm
2 x 10.0mm

I wonder where the 1.0mm is? Answer in the shop where it should be..gathering dust to boot.
