Question about cable and security light

[Daz134]

Hello

We have purchased a security light LINK TO LIGHT

Im looking at adding this light with Flex cable of a run no more than 10 meters on a 3 AMP 3 pin plug.

I would have thought that 1.5mm flex cable will be over kill for this light due to the 1.5mm flex being up to 15 amps in current.

Would I be ok using a smaller cable of 1mm or even 0.75mm flex with a 3amp 3 pin plug?

I would appreciate your thoughts

Thanks

Thanks for the advice

When buying that cable should I go with 0.75mm, 1mm or 1.5mm

Thanks

I think you will find the smallest is around 1.5mm, but these folk do 1mm:

H07RN-F Rubber Cable - 3 Core 1mm2/ HO7RN-F-3C-1

For the sort of length you need, the postage is probably bigger than the cost difference in cable size!

You might find a CEF locally and they do 1.5mm (if they are in stock) so collecting might be best:

1.5mm² 3 Core HO7RNF Rubber Flexible Cable (Cut Length Sold By The Mtr)

1mm is fine and is the smallest allowed for lighting circuits:

Great thank you

Would you suggest going with 1.5mm and not 1mm or even 0.75mm

Great thank you.

So 1mm is fine. Would it be bad if I was to go with 1.5mm

No. 1mm is slightly easier to terminate.

Not at all. Only issue is with some fittings that struggle to take 1.5mm, but it is not uncommon for lights to be wired in 1.5mm for fixed circuits, even though 1mm is allowed.

Great thank you so I will go for the N.B H07RN-F in 1.5 going into a 13amp plug fitted with a 3 amp fuse
