I will be running new outlets (both 110 & 220) in my shop/garage. Ideally I want to have the power to my 220v machines run from above so they don't create an obstacle course on the floor. My question, is it ok to just have the twist/lock outlets installed on the rafters above the machines? For the 110 power (away from the wall), I already have two ReelCraft retractable lines already in place. TIA
