I'm running a new circuit down one wall and around the back of the garage. I plan to have two duplex outlets along the side wall and then back where a workbench will eventually go, I plan to have 3 outlets (four gang). What's the best height to place these at? 60" would get them out of the way of 4x8 sheets of plywood stacked along the wall and over any future work benches. Is there any reason I would want them lower? I'm just trying to plan for all future possibilities. I do plan on drywalling or pegboarding over it, so it will be semi permanent.
