I was called out to a job that had 2 single conductors (#12 or #10) ran from the farm house to a small out building. The run was about 90 ft from the house to a utility pole then to the building on insulators. A tree branch came down and broke the hot wire. My question is it still legal to run a circuit this way. The circuit is a 20 amp and only operates a single liht and outlet inside the building. The only code reference I could find was NEC 225.6(a) The house is located in a small town in northeast Ohio. Thanks for the help.
