I am wiring a wood shop and have to hook up a drum sander. This is 230v 1 phase. We are going to install floor boxes for the machines in the center of the work area to avoid cord drops being in the way. This particular machine doesn't come with a cord, though the manual implies that you can wire it with a cord and plug or hardwire it. The owner wants it cord and plugged. It has a 5hp and a 1/4hp motor. All it mentions is to use a UL/CSA listed cord and plug. 430 mentions that to use a cord and plug as a disconnect for motors, it must be hp rated. I can't for the life of me find a 5hp or better rated single phase cord. The owner found another machine (different brand) that is 5hp with a permanently attached dryer cord on it and wonders why that one has it. This isn't an appliance and it falls under 670 which doesn't help either. What am I missing here?
