Hi Simon, I would say medium sized ones . Is that too close, or am I safe? The first tip to understanding how to identify low voltage vs high voltage is that at 120V and below, it is perfectly safe to approach power lines (be they overhead or buried) without a personal safety distance, provided you have insulated yourself. The total voltage of a two-phase line equals 230 kV (230 kilovolts). Hi Patrick Never purchase a home on a crescent shaped road ending.
