I bought a new jointer, and picked up a used plainer. Both are 240v and both need to get an electrical outlet for the wall.
Both machines have a magnetic starter on them so they are overload protected. The plainer is rated at 12amps, and the jointer at 15. Now I know from the electrical code that it is fine to put on a 20amp breaker with 14gauge wire and a nema 6-15 plug as per the section of induction motors with overload protection
But thinking about it some more, I figure that I am going to have to run another wire into the shop anyways, so why not just run 12gauge to begin with. Am I allowed to put a nema 6-15 plug onto a true 20amp circuit? I'd rather not have to replace two perfectly good power cables to get from the nema 6-15 plug that is on both machines to a nema 6-20.
I know that the fuse inside the electrical pannel is there purely to protect the wire that is inside the wall, and not the device that is plugged into it. But at 240v they change the style of the plug as you change the amperage.
