First time running overhead drop from home to unattached garage, main panel more than able to support service... need 60' to 70' run. I am familiar with NEC but not a professional. I have done home wiring before, put in main panels and sub-panels, hot tubs, etc... with oversight in the past by a contractor friend so I know all is ok.... even passed inspection :)
Sect 225, 338, 340 and other codes regulate type of overhead outside cable (i.e. weather resist, UV, voltage rating...) Understand height above roof, service head, drip loop, securing with Gav stranded line between building and drop to garage.... Also looking at voltage drop calc trying to keep within 3% (5%max) drop I can do.
Anyway, I am burnt out as I am trying to figure out which type of insulated overhead cable to use. Home depot has nothing. Even though I will be using 60 amp, I will be running 100 amp service and I recall in NEC I thought all overhead drops had to be a min of 100 amp, and underground service min 200 amp. In past have used CU, but thinking of now using AL which I know on the chart will effect my size wire. 220vac run.
Sorry for long winded, never been here before.... just need some part number to something to figure out the type of outside drop wire to use. Using 4 (3 + ground)conductors as this is a sub-panel, and not a drop from a power pole...
