100A Manual Transfer Switch for Two Power Sources

100A manual transfer switch designed for switching between two power sources such as utility power and solar inverter power according to the old description. This type of switch is used in systems where the user needs to manually select the supply source in a clearer and safer way than random wiring, such as changing home lighting or selected loads between grid power and a backup source.

This switch is useful in solar and backup power systems when one source needs to be disconnected and another source selected manually. The image shows a large mechanical changeover switch with an operating handle, and the old product name mentions 100A capacity. Current rating, voltage, wiring method, and system compatibility should be confirmed before installation.

This product handles dangerous electrical power and should be installed only by a qualified electrician. Proper cable size and protection devices should be used, power should be disconnected during installation, and the switch must not be wired in a way that connects two power sources together incorrectly. Wiring mistakes can cause short circuits, inverter damage, or user safety hazards.
