The output of smaller turbines is 12V, 24V or 48V direct current, with larger units outputting alternating current in 3-phase supply through a remote controller box. To get power from the tower there must be a connecting terminal to the turbine of "flying leads." This is a direct current system with two wires: positive and negative. It outputs 3-phase alternating current with three wires but no polarity or connection issues.

The wind turbine electrical leads connect to the tower wires through a weatherproof enclosure placed near the tower's top. You should ensure that leads from the tower to the house are weather-resistant, flexible, insulated and protected; if not, ensure that they are in some form of conduit strapped to the tower's legs with ultraviolet-protected cable clamps or tie wraps.
