I'm in the midst of designing a control panel and wanted some opinions.
I need to have a 1" KO for a communications cable to pass through. The way I've laid it out, I have a pair of 1/2" KOs on both sides of a 1" KO. Anyone have opinions about how much clearance is needed between the 1/2" and 1" KOs for turning a wrench? I think that most of the time the 1" KO will be filled with a plastic grommet, so I'm not worried about clearance for tightening EMT fittings, but I'd like to make sure I'm leaving space enough in the event the panel isn't installed as I expect. The area I've reserved for these three KOs is 6" wide by 4 1/2" deep.
