A double pole switch is a type of electrical switch that includes two circuit breakers connected to a single switch. This type of switch is often used to control a single appliance from two different sources, such as a boiler and a hot water heater. Understanding the wiring diagrams associated with double pole switches can help in correctly wiring and installing them.
Standard Wiring Diagrams
Typically, double pole switches are connected to a source of electricity via two 120-volt hot wires, a neutral wire, and a ground wire. The wiring diagram for a double pole switch shows how each of these wires is connected to the switch. The hot wires are connected to either side of the switch, and the neutral and ground wires are connected to the corresponding terminals.
Additional Wiring Considerations
When wiring a double pole switch, it is important to take into consideration the load of the appliance it is connected to. If the appliance has a high load, such as a hot water heater, then the hot wires should be connected to the switch in such a way that they alternate in order to reduce the risk of overloading the switch. Additionally, a properly rated circuit breaker should be installed to provide additional protection in the event of a power surge or overload.
Conclusion
Double pole switches can provide a convenient way to control an appliance from two different sources. Understanding the wiring diagrams associated with double pole switches is an important part of correctly wiring and installing them. Additionally, it is important to consider the load of the appliance when wiring the switch and to install a properly rated circuit breaker for additional protection.
