Main switch and selector switch wiring:

This diagram shows the Main switch and selector switch wiring. In this circuit, we use a main switch, a selector switch, a magnetic contactor with overload, a DP MCB ( Double Pole Minature Circuit Breaker ), and a Compressor. First, we need to connect the DP MCB with a power source, then connect the magnetic connector with DP MCB, then connect the selector switch and main switch. Lastly, we need to connect the compressor to the circuit breaker.

Components used to make the Main switch and selector switch wiring:

01. Main Switch:

The Main Switch is Connected to the live and Neutral Wires. It is Used to Cut the Connections of the Live Wire as well as the Neutral Wire Simultaneously from the Main Supply. The main switch Isolates the Electrical supply from the whole installation so that it can be turned off for Servicing or Maintenance. It also provides overload protection for the mains cables (on newer switchboards) so that they will trip if the cable is Drawing too Much Power.

02. Selector Switch:

A Mechanical Switch That can be rotated Left, right, or center to open or close the electrical contacts is known as a Selector switch. The Main Function of This Selector Switch is to Control Devices and also to Switch Between a Minimum of 2 or Above Electrical Circuits. The Perfect Used for Selector Switch is When Used for Controlling an Output of a Device. We know that a Selector switch is Used to control the electrical current flow in a Circuit it can also be used to both Initiate and inhibit the Current Flow.

03. Magnetic Contactor:

A magnetic contactor is an electromagnetic switching device. It is generally used for controlling three-phase motors. The operation of a magnetic contactor is similar to that of a relay, but a relay is used for low-power or low-voltage connections, and a magnetic contactor is used for high-power or high-voltage connections. As soon as the supply is applied to the magnetic contactor coil, its normally open contacts are closed and normally closed contacts are opened and the associated devices are also operated. This is how a magnetic contactor works.

04. Overload Relay:

Overload Protection is Protection Against a Running Overcurrent That Would Cause Overheating of The Protected Equipment. Hence, An Overload is Also a Type of Overcurrent. Overload Protection Typically Operates on an Inverse Time curve where the Tripping Time Becomes less as the Current Increases. This Overload Protector is an Essential Component for Many Sockets. The Top-Quality Overload Protector can Effectively Protect Electrical Products from Power Surges.

05. DP MCB:

DP MCB In Two Pole MCB, switching & protection is affected in phases and the neutral. A Double Pole or DP Switch is a Switch that Controls two Circuits at the same time. In terms of Residential Switching, this Normally means it Switches the live and Neutral at the same time. In Layperson Terms, Double Pole switches or DP Switches are Exclusively Designed to Control two Different Electrical Circuits at the same time, which allows the Appliances to Isolate in a safe and reliable manner. Fan or light Combinations and Medical Equipment are some of the many applications for DP Electrical Switches.

06. Compressor:

Air is Compressed by air Compressors. Air Compressors draw in Air at an Inlet Valve, They Then Compress The Air to The Required Volume And Release The Pressurized air through the discharge Valve into a Storage Tank. Air Compressors Work by Forcing Atmospheric air Under Pressure to Create Potential Energy That Can be Stored in a Tank for Later use. Just like an Open Balloon, The Pressure Builds up When the Compressed air is Deliberately Released, Converting The Potential Energy into Usable Kinetic Energy.
