Cannot find the code req for running 1/2" emt from a commercial (restaurant) building to a outside sitting area (gazebo). Its about 7 or 8 ft from where I would run power from the building to the wooden structure (large gazebo). Is this legal? how would I support the emt pipe? How high do I have to be? Is there a min or max distance I can run pipe in free air? The other option is chip out the cement and go underground. Also, do they make a outdoor ceiling fans made for wet conditions, direct rain? not patio cover fans. Havent come accross this in my 25+ years of elec work. Any info would help.
