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

Right. Well... this has all taken quite a turn. Who'd have thought all hell would break loose several months later. I'm the OP and just to justify my choice of cable, I must admit I had no idea what these cables looked like in real life, so getting the lightest possible seemed like the right thing to do. It's working very well, and since there still are forum voices that say it's okay, I'll stick with it. I do understand that more is better in these things, but it's all installed and, I'd like to think, behind me.

It's been interesting, though, and thanks to all. This is a great and helpful forum!
