My garage doesn't have any wallboard. The EMT conduit is open and not hidden.
Is there a height minimum from the floor for running emt conduit from the switch box (normally 48") to a fluorescent light fixture over a workbench in the garage?
In short, what is the minimum distance a fluorescent light fixture or EMT conduit can be over a workbench from the floor?
Also, should I have the emt conduit that affixes to the light fixture run toward the ceiling first (upwards) instead of parallel the way I have it directly to the outlet?
