How to distinguish track spotlights with two wires, three wires and four wires? What do you mean by two lines, three lines and four lines? Is it wiring or guide rail?

There are two-track and three-track in international standards. Now 3-wire track is widely used, which has high safety. The characteristic of track lamp is that it can be installed along the track, and it can be installed at different positions and different angles at will.

A double-track track has two copper wires, a live wire and a zero wire. The third wire is connected with two live wires and a zero wire. There are three live wires in the four-wire track, and a zero wire is directly connected to the track shell, which is the ground wire. Therefore, the guide rail head matched with the four-wire track has six contacts, which are disconnected when it is adjusted to 0, connected with a live wire when it is adjusted to 1, and connected with two live wires when it is adjusted to 2, and so on.
