Are the lights in the elevator divided into live and zero lines?

Generally, there is no difference between live wire and neutral wire in the lights in elevators. The lights in the elevator are usually connected to the control system of the elevator and are powered by DC power instead of AC power. Therefore, there are generally only two wires for the lights in the elevator, one is positive and the other is negative. The lights in the elevator usually don't need grounding, because the elevator itself has a good grounding system. So generally speaking, the lights in the elevator have no distinction between live and zero lines.
