Which thickness CY cable do I need for 1.5kW spindle?

It is thinner and lighter but it should be 1.5mm2. 0.75mm is OK for control signals but actually too thin for the power.

You do not say that you prefer or recommend using thicker cables to be on the safe side or you normally have them at hand or you don't mind wasting a valuable metal with finite resource here on earth. But you say that a 1.5KW spindle cable should be 1.5mm2 and the control cables 0.75mm2 (when most control cables are 0.25mm2). This approach is all wrong!

Yes, well... many people have electrical issues...

I think that line is pretty clear, but sure, this is the internet, so if something can be misinterpreted you can be sure someone WILL misinterpret it and start a stupid fight about it.

Regarding the environmental issues... well... the way I see it is that basically EVERYONE on this forum, and every other similar forum, is wasting valuable metal with finite resources here on earth, because hand on your heart... how many of us MUST have the machines we have? To me this is just a hobby, as it is for most people on these forums. You, and everyone else on this forum (including myself) are HUGE contributors to global warming, the using up of finite resources and everything else environment activists can come up with. So, please don't beat your chest and be proud about yourself just yet or accuse me for being an enemy of the earth... you know nothing about me or how I am living, so leave that out.

Besides, who says that the cable must be wasted? It can be used in another project or sold to somebody else for re-use.
