"40/0.16" refers to the construction of the cable's conductors.
The first number (40) indicates the number of individual strands or wires that are twisted together to form the conductor. In this case, there are 40 strands.
The second number (0.16) refers to the diameter of each individual strand, measured in millimeters. In this case, each strand has a diameter of 0.16mm.
So, the full designation "40/0.16" means that the cable has 40 individual strands, each with a diameter of 0.16mm, twisted together to form a single conductor. This type of cable is commonly used for low voltage applications, such as in electronics and small appliances.
Cool! Thanks for the idea! I still get stuck in here lately, especially the following 0.16. as you mentioned, 0.16mm for "each" strand, that means the very little thin copper in every LNE? At first I thought it's the size of each LNE, means Live cable 0.16mm and so on. 😅
So, in Malaysia we always mention Cable size in 1.5mm, 2.5mm, 4mm , right? But in US they called that AWG/Guage? In "mm" seems better way to understand ya.

There are a few methods you can use to verify if a copper cable is genuine copper:
Look for a copper hallmark: If you have access to a magnifying glass, you can look for a hallmark on the surface of the copper cable. This hallmark will typically indicate that the cable is made of genuine copper.
Check the color: Copper has a distinct reddish-brown color, so if the cable has a different color or appears to be painted, it may not be genuine copper.
Check the weight: Copper is a dense metal, so a genuine copper cable should feel heavier than a similarly sized cable made from another material. You can compare the weight of the copper cable to a known copper sample of the same size.
Conduct a magnet test: Copper is not magnetic, so if the cable is attracted to a magnet, it may not be genuine copper.
Test the conductivity: Copper is an excellent conductor of electricity, so you can use a multimeter to test the cable's conductivity. Touch one end of the multimeter to the copper wire and the other end to a known conductor. If the meter reads a high level of conductivity, the cable is likely genuine copper.
It's important to note that some copper cables may be coated with a layer of another material, such as tin or silver, so these tests may not always be conclusive. If you're unsure about the authenticity of a copper cable, you can consult a professional or take it to a testing facility for analysis.
Wow .. love it. Thanks for your efforts! Magnet seems the best way to check ya??
