The right way to Wire A Double-Pole Three-Way Switch
A double-pole switch allows you to manage two separate circuits using the identical switch, while a three-way switch allows you to manage a single circuit from two different locations. A double-pole three-way switch is ready to integrate both of those functions into one. With this switch, you will be able to regulate two separate circuits from two different locations, for example, with the ability to simultaneously turn on a light and a fan from next to the door you’ll use to enter a room, after which turn them off at the identical time with the identical type of switch next to the door where you exit the room. A majority of these switches could also be used to regulate 240-volt circuits.
Things You’ll Need
Two double-pole three-way switches
Prepare two cables, each with three wires inside: the live wire, the bottom wire and the neutral. From each cable, connect the three wires to their respective terminals on the circuit breaker panel. The terminals on the panel are usually marked and may easily be identified. Prepare two other cables, each with two wires inside, by replacing the exposed portion of insulation of the neutral wires with insulation that is of the identical color because the live. The live wire is often characterized by red or brown insulation.
Screw the two live wires from the 2 cables originating from the circuit breaker panel onto the 2 input terminals on the first switch, noting the label on the terminals. The switch has two terminals on one side and four corresponding terminals on the opposite; for each input terminal, there are two output terminals on the switch. Connect the 2 cables with only two wires inside to the opposite four terminals on the other side of the switch, each cable’s two wires connected to adjacent terminals. Each of the two cables should represent a special circuit.
Connect the identical two cables with two wires inside to the four terminals on the second switch, ensuring that each wire ends up joined to a terminal labeled exactly the same as on the first switch.
Connect the live wires of two more cables, each with three wires inside, to the 2 terminals on the opposite side of the second switch, paying careful attention to the labels. Connect the 2 neutral wires of these two cables to the neutral wires from the first two cables from the circuit breaker panel using wire connectors. The neutral wires thus will run straight through to the appliance or light being controlled by the switches. Be certain that the neutral wires are joined along with respect to their different circuits. Connect the bottom wires to the bottom terminals of the switches.
Connect two bulbs or devices to the end of the second pair of three-wire cables, each to a special circuit, and test the connections to see whether they’re working properly.
