Interruptor Relay Wiring Diagram Basics & Tips

Interruptors or relays are key components of any electrical system and wiring diagrams are a visual representation of the layout of these items. Wiring diagrams provide a precise and accurate representation of the various parts of the electrical system, including the connections and their locations. By understanding the basics of reading and interpreting a wiring diagram, it becomes easier to troubleshoot any issues or to make necessary changes. This article will delve into the details behind reading and understanding an interruptor or relay wire diagram.

Understanding the Terminology

Before being able to effectively read a wiring diagram for an interruptor, one must first understand some common terminology. The following is a list of some common terms and symbols used in wiring diagrams:

Voltage – A measurement of the force of electricity

Current – The flow of electrons

Resistor – A component that limits current flow

Diode – A semiconductor which allows for current to flow in one direction only

Capacitor – Component used to store electrical charge

Switch – A device used to turn a circuit on and off

General purpose – An open terminal or a connection symbol

Ground connection – A connection/path to earth or to a metallic mass

Understanding the Components

Wiring diagrams for interruptors or relays typically include five main components:

The Controller

The Load

The Interruption

Interruptor Terminal

Ground

The controller is the main electrical connection point, while the load is the device being powered by the interruptor or relay. The interruption routes voltage, while the interruptor terminal provides the electrical connection needed to switch the power on and off. The ground acts as the return path for all electrical signals.

Reading the Diagram

Reading the wiring diagram can be best accomplished in two steps. First is to identify the symbol for the component, such as a controller, interruptor terminal, ground connection, etc. Second is to understand how the symbol is connected to the other components in the circuit. The most common way of indicating connections is through arrows that show the current/voltage flow between components. The direction of the arrow indicates how the electricity is flowing.

Common Errors in Reading Wiring Diagrams

When reading wiring diagrams, it is important to be aware of some of the common mistakes that can be made. The most common mistake is not understanding the direction of the arrows that indicate the current/voltage flow. Another mistake is labeling the components incorrectly, or omitting them altogether. Finally, mistakes can be made when connecting a component to the wrong terminal or not properly grounding the circuit.

Conclusion

Interruptors or relays are fundamental parts of any electrical system and wiring diagrams are an efficient way to get a desired result. Understanding the basics of reading and interpreting a wiring diagram helps ensure that the wiring process goes smoothly. Knowing the common terminology and the different components of a wiring diagram is key to correctly interpreting an interruptor wiring diagram.
