    What wire or cabling is everyone using for the connections to the motors. I need no more than 18ga wire for my motors but am finding it difficult to find 18-3 S.O. cable. Thats 3 and a ground. This is used most times as I can see as extension cable or easy pull cable in factories. But they mostly use 16ga. The reason I want S.O. is for is't being very flexible.

    Thanks
    Steve

    Not sure where you are located, but my local Home Depot has 18 gauge stranded or solid that is shielded. I plan to use shielded 18-4 stranded for the flexibility for motors and shielded 18-2 stranded for the limit switches. I believe it is somewhere in the $0.25- $0.35 per foot if bought from a bulk roll. I can't remember the exact price. The wire has the additional ground wire for the shielding.

    I did not look for 18-3.

    I think they build them in house. Drop them a line and see if they have just the wires available.

    Very flexible. More so than the other cable I was using.
    It could be the lack of shielding, I don't know, but it works for what I need.
    I'm guessing it goes down to a 2" radius, or so. Maybe less.
