The difference between 1 phase and 3 phase track lighting


If you're looking for track lighting, you must have heard about 1 or 3 circuits or phases already. On this page, we'll explain the difference between those two.

What is a phase?
In a standard power cable with three veins, you'll find a phase, a neutral wire and a protective earth/ground wire.

The phase is the wire that's under voltage relative to the neutral and protective wire. The phase leads the electrical current, together with the neutral wire, from and to connected equipment.
