Multymeter.com–Electrical Engineering: Hello everyone, in this article we will discuss the functions and how to install relays in the electrical panel. Relay is an electrical panel component that works on the principle of electromagnetic induction. Relays can be used to control large electric currents using small electric currents. Relays can also be used as interlocks, which are circuits that function to secure the processes in the circuit itself in case of unwanted intervention. The relay consists of two main parts, namely electromagnet and mechanics. The electromagnet is the part that functions to move the switch or breaker contact, while the mechanical is the part that functions as a connector and circuit breaker. The following is a more detailed explanation of the function and how to install the relay in the electrical panel.
Function of relay in electrical panel
The function of relay in the electrical panel is as follows:
• Relays can be used to control large electric currents using small electric currents. This can save costs and space in the electrical panel, as well as reduce the risk of short-circuiting or overheating the electrical circuit. For example, relays can be used to control electric motors, lights, pumps, fans, etc.
• Relays can be used as interlocks, which are circuits that function to secure the processes in the circuit itself in the event of an unwanted intervention. For example, relays can be used to prevent two or more different conditions from acting together, such as preventing an electric motor from rotating when an electrical panel door is opened or preventing a light from turning on when there is motion in front of a sensor. .
• Relays can be used to change the function of switches or change contacts as needed. This can increase the flexibility and efficiency of the electrical panel. For example, relays can be used to change a single switch to a double switch, or to change a normal switch to a reversed switch.
• Relays can be used to extend the range of switches or switch contacts. This can facilitate the operation and monitoring of the electrical panel. For example, a relay can be used to connect a remote switch or switch contact to a desired electrical circuit, or to turn on an indicator light in an electrical panel.
• Relays can be used to protect electrical circuits from interference or damage. This can increase the safety and convenience of the electrical panel. For example, relays can be used to cut off electrical power when there is overcurrent, overvoltage, overtemperature or a short circuit in an electrical circuit.
How to install a relay in an electrical panel
The way to install the relay in the electrical panel is as follows:
1.Make sure the electrical panel is turned off and no electric current is flowing. This is to avoid short circuit or electric shock when installing the relay.
2.Choose a relay according to the specifications and needs of the electrical circuit to be controlled. Consider the type, size, shape, number and function of the switch contacts in the relay. Also pay attention to the working voltage and current in the relay.
3.Prepare the necessary tools to install the relay, such as screwdrivers, pliers, cables, plugs and others. Make sure that the tools are in good condition and clean.
4.Place the relay in a suitable and safe position in the electrical panel. Make sure that the relay is not exposed to water, dust, heat or other objects that may damage it. Also make sure that the relay is easy to reach and see.
5.Connect the wires to the relay terminals according to the desired electrical circuit diagram. Make sure the wire connections are tight and nothing is chipped or broken. Also make sure that the polarity of the wire matches the relay terminals.
6.Install a socket or locking screw on the relay to secure its position and wire connections. Make sure the socket or locking screw is not too tight or too loose.
7.Recheck all components and wiring in the electrical panel. Make sure nothing is wrong or missing.
8.Turn on the electrical panel and test the relay function by operating the switch or switch contact connected to the relay. Make sure the relay operates correctly and as required.
Conclusion
So, an explanation of the function and how to install the relay in the electrical panel. Relay is a component of the electrical panel that works on the principle of electromagnetic induction. Relays can be used to control large electric currents using small electric currents, as interlocks, to change the function of switches or switch contacts, to extend the range of switches or switch contacts, and to protect electrical circuits from interference or damage. The way to install a relay in the electrical panel is to choose the right relay, place the relay in the correct and safe position, connect the wires to the relay terminals according to the electrical circuit diagram, install a plug or locking pin on the relay, and test the relay function.
