Hi,
A cable stated as 40/0.16 what does it mean?
0.16 means 16mm?

40 is length.. 0.16 is diameter... You nak buat apa? Wire lock?

Its 0.75mm2

Assume you are asking about 3 core wires

Thanks guys for your prompt reply!

I see. Yg 0.16 diameter tu kira yg luar ke (3 wire dlm), atau pun yg dlm tu (1 wire 0.16 diameter)?

Utk lampu sambungan biasa. Boleh kan?

Oh 0.75mm², how do you translate?
Yes. 3C wires!

The wire contains 40 strands with each strand maximum diameter of 0.16 mm.
Cross section calculation is
= ((diameter/2)²) x Pi) x (number of strands)
= ((0.16/2)² x 3.14159) x 40
= 0.8 mm² nominal

40strand of 0.16mm2diameter = 0.73mm2
max can use 6ampere if its copper.

good enough for small led lights

016 is the size of individual copper strain
i think
and theres 40 of this strains

Wah... You are Expert 😜
Could you "teach" a little bit of the format? Interesting & useful 👍🏻

Thanks for confirming! 👏🏼
So the 40 is Strand! I see .
And this format "0.16mm2diameter = 0.73mm2" is from the chart given above?

Which means 0.16x3 = 40? 😲

0.16 is the diameter
R is diameter bahagi2
To get area is pi r kuasa Dua remember?

So 3.142 x 0.08 x0.08

OMG really forgotten 😭
You are cool! So, you are in the field?

In jagung field ya

very humble good job man

Haha. Funny but humble 👍🏻😁

What wiring work you doing?

Please find the sizing over here.

1.5mm2 for lighting/fans,
2.5mm^2 for rings sockets (regular non high current sockets)
4mm^2 for higher loads / kitchen

40 strands wire is for power circuit or signal?

Thanks for the information! I'm not Pro , just love to DIY 😁
Learned some ideas from Seller, 1.5mm for normal appliances, 2.5mm for Appliances like Microwave and Oven.

The 4mm wires for Kitchen means? Sockets or Appliances?

Terminate to 3 pin socket

ceo684 can advise.

usually all these weird size like 40/0076 or 70/0076 don't meet ST requirement for electrical wiring.

also, there are substandard cables (fake copper) around in the market.

this is something that one should read up on as electrical safety is not to be trifled with

should be power, signal dont need 40 strands. even so still missing the material, like copper or zinc, copper is alot better, but zinc is cheaper.
