Its also because the wires feeding electricity to the switch are larger and this is due to the fact that double pole switches are usually used to control 240 volt circuits. The double pole switch is commonly used in industrial applications but can be found in some home wiring systems.
How To Wire A Double Pole Light Switch Quora
What does double pole mean. Single pole switches disconnect the phase conductor only while double pole disconnects both phase and neutral. With 2 inputs it can connect to 4 different outputs. Each input has 2 corresponding outputs that it can connect to. A double pole switch is usually a bit larger than a single pole one but that isnt just because it has to accommodate two poles instead of one. These breakers can be used to serve two separate 120 volt circuits or they can serve a single 240 volt circuit such as your central acs circuit. Double pole breakers on the other hand are typically rated for 20 to 60 amps and supply 240 volt power to large appliances like electric dryers and ranges.
Double pole breakers have two hot wires that are connected by a single neutral wire. Double pole thermostats a single pole thermostat opens the circuit by cutting current through one or the other of the hot wires. Each of the terminals of a double pole double switch can either be in 1 of 2 positions. The standard electrical dictionary 000 0 votesrate this definition. Double pole sockets are often used in home lighting situations where red wires are live and black are neutral and the green wires are earth or grounding wires. Double pole sockets switch the live and neutral conductors.
There is not requirement that you use dp switches but i would recommend it anyway. Double pole thermostats open both hot wires. This makes the the double pole double throw switch a very versatile switch. Like the single pole switch a double pole switch has onoff markings and controls a device or equipment from one location. Double pole sockets operate two separate electrical circuits in a single circuit. A double pole double throw dpdt switch is a switch that has 2 inputs and 4 outputs.
That means if theres a short circuit on either of the poles hot wires both trip. A heavy switch for central station work that connects and disconnects two leads simultaneously. Since the power is off someone might try working on the heater and get electrocuted by connecting any part of the circuit to ground. Theyre double wide breakers that take up two slots in the breaker box and have a toggle switch thats twice the length of the toggle on single pole breakers.
