Eli5: Power lines on pole into house

425 viewsEngineeringOther

Why are the power lines on the poles so small in gauge but for example my 200 amp service has a much thicker wire going into the panel. ?

The wires between the poles are at much higher voltage (7.2KV or 14.4KV in the US). This allows smaller wires to save weight and money, but that’s why you have transformers on the poles.
