I think you all for your help, I think I am going to go with the messenger cable with UF either tie-wrapped or wrapped to it. Is there any listing to be concerned with as far as the messenger? Can I use normal steel cable, in the area of 1/4"? I will be sure and keep it about 10' as per 225.18 and will bond it to the EGC. Also will run pipe, schd 40 pvc, up to where it attaches to the shed, put on a weatherhead and run into a disco. Sound good? Again, I think you all for your help.
