A home inverter wiring diagram that illustrates how an inverter system is connected to supply backup power during outages. The setup consists of a battery, an inverter unit, and switching circuits that allow seamless transition between the main power supply and inverter power. The main power supply charges the battery when electricity is available, while the inverter converts stored DC power to AC when needed. Various household appliances, such as fans, lights, and sockets, are connected to the inverter supply, ensuring uninterrupted operation. Protective components, including circuit breakers and fuses, are included for safety and to prevent overload. This wiring configuration is common in homes and offices where backup power is essential.

Automatic and Manual Water Pump Control System with Timer

Brief Explanation:

This diagram illustrates a three-phase water pump control system that can operate in manual or automatic mode using a digital programmable timer switch. Key components include:

Contactor: Controls the main power to the motor.

Overload Relay: Protects the motor from overload.

Digital Timer: Automatically controls pump operation based on set schedules.

Selector Switch: Allows switching between Manual, Off, and Auto modes.

Push Buttons (NO/NC): Used for starting or stopping the motor manually.

MCB (Miniature Circuit Breaker) and RCCB: Provide protection against short circuits and leakage currents.

This system is commonly used in water pumping stations or irrigation systems....
