I have a job I have to do plans have been approved. Only thing is I’ve never ran DC conductors over head and it’s over 600 volts. Plans say 80’ conduit run between buildings looks like it’s a commercial driveway I will be going across. plans also say weather head on both roofs. Without going down a wall like a service with ridged conduit How would I secure my conduit. Does anybody have any experience with this thanks in advance
