What size armoured cable do I need???

[welshviking]

Hi there,
I've just built a shed and want to run power to it for a double socket and 3 light fittings.
I would need about 25-30 meters of cable but wanted to check on the minimum diameter I could run with.

Thanks guys

Mike

I would say minimum outer diameter of the steel wire armoured cable to be about 16.5mm.

And that's notifiable work to building control which requires a building regulation certificate.

The correct term is cross sectional area,the work is notifiable and it would probably cost you more to notify it than to have the job done by a pro,not trying to put you down but it,s not just a case of what you can get away with,it,s what you need to do the job safely and in accordance with the regs,unfortunately it,s not as simple as the diy stores say it is.

PI R(squared) is the cross sectional area. Where PI is 3.141....etc and R is the Radius. or half the diameter.

According to an American statute of the 1890’s it’s 4
3.142 was to difficult to work out so they went for the easy option.

PS the OP’s gone.

i'm surprised americans could multiply by four. they only have 2 hands, 2 eyes, 2 legs, and they came int0 2 world wars 2 years late.

I have a warm fuzzy feeling inside knowing that I've really helped someone today. Or it may be the cider?

Is that why they still do everything in old money ie. inches, feet and lbs?
