A Manual Changeover Panel is an electrical control box with switches that let a user physically select between two power sources, typically the main utility grid and a backup generator, ensuring safe, controlled transfer for uninterrupted power in homes, businesses, hospitals, or industrial sites, preventing backfeeding to the grid. It involves circuit breakers and a main switch to move loads from one source to another, offering a reliable, lower-cost alternative to fully automatic systems. How it Works

• Two Sources: Connects your primary power (grid) and a secondary source (generator/inverter) to the panel.
• Manual Selection: A lever or switch on the panel is physically moved to choose which power source feeds your circuits.
• Safety: Prevents both sources from being connected simultaneously, stopping dangerous backfeeding into the utility grid.
• Indicators: Often includes lights to show which source is active and if power is available

Key Features

• Manual Operation: Requires human input to switch.
• Durable & Safe: Built with breakers and overcurrent protection.
• Applications: Homes, small businesses, critical loads, where manual intervention is acceptable. 

Manual vs. Automatic

• Manual Changeover: User flips a switch; good for planned outages or cost-sensitive backup.
• Automatic Transfer Switch (ATS): Detects outage, starts generator, switches automatically; for critical, seamless power. 

A 425V Automatic Changeover Panel is an electrical panel used for automatically switching the supply from one power source to another when a failure or fluctuation occurs in the primary supply. This type of panel is commonly used in industrial, commercial, and residential setups to ensure continuous power supply.
