Frank, The code section uses the words "service conductors" so in my opinion it applies to both service drops and service entrance cables. Is that window designed to be open? If not there is no violation in the current code. I would like the 3' restriction to apply to all windows, not just those designed to be opened, but that's not what 230-9 says. Any overhead drops near windows interfere with the placement of fire service ladders in the event of a fire. Don(resqcapt19)
