![]() The double pole switch breaks both wires of the 240VAC at the same time to open the circuit and closes at the same time to make contact and close the circuit. A third green wire is connected to the ground screw. 240VAC double pole switches require both 120VAC hot wire, which are usually a black and red wire connected to the switch. In domestic applications these circuits power clothes dryers, electric ranges, electric hot water heaters or air conditioning window units, that are on a dedicated double pole breaker in your load center. This circuit is typically used on a larger load like a motor or an appliance that requires 240VAC.Ī double pole switch is used with a 240VAC electrical supply. Occasionally the circuit may be on a double pole breaker, making the circuit 240VAC. Turn OFF your home’s circuit breakers and if you have metallic wall-boxes, place a strip of electrical tape over the screws on the side of your Klever Switch before turning the circuit breakers. ![]() Choose the two Klever Switches that will control the same lights. Single pole and 3-way switches are used for low current 120VAC (Volts of Alternating Current) applications. There are different ways to connect up two way lighting circuits, one way is to use a twin & earth cable between the two light switches. Only 1 Switch is Wired to the lights, Neutral Wire Required in Location 2: 1. For the third terminal, one switch is connected to the hot supply wire while the other switch is joined to the light. Two of these take traveler wires that go from one switch to the other. They are wired so either switch can work the light, regardless of the setting of the other.Ī 3-way switch is larger than a single pole switch and has three screw terminals for wiring connections, plus a ground. These are used in pairs, with one at each switching location. Three core and earth cable is required to install two or three way switching and this should be run from the first light switch to the second and then wired as. In some applications however, such as hallways and larger rooms, having a single switch can be inconvenient, so it might be useful to control the light from two locations, and this is the role of the 3-way switch. There's also a ground wire to protect against electrical faults. It's called a single pole switch because there are two wires connected or separated by the switch mechanism. 3-wayĪ single pole switch is used to control the light in a small closet or bathroom. It's important to pick the right type of switch for the application. Switches are used to operate lights, fans, and even large electric motors, but they're not all the same. ![]() ![]()
