Power Flow
In three-way wiring systems, understanding power flow is essential for ensuring the proper functionality and safety of the circuit. Power flow refers to the path that electrical current takes through the circuit, and it is determined by the positions of the three-way switches.
Three-way switches have three terminals: common, traveler 1, and traveler 2. The common terminal is connected to the power source, while the traveler terminals are connected to the load (the light fixture or other electrical device being controlled). When one switch is in the “on” position and the other switch is in the “off” position, current flows from the power source through the common terminal of the “on” switch, through the traveler terminal of the “on” switch, through the traveler terminal of the “off” switch, and then to the load. When both switches are in the “on” position, current flows from the power source through the common terminal of one switch, through the traveler terminal of the same switch, through the common terminal of the other switch, through the traveler terminal of the other switch, and then to the load.
By analyzing power flow in three-way wiring diagrams, electricians and homeowners can ensure that their electrical systems are safe and efficient.
