A 100A 2-Pole Double Power Load Switch Blade (commonly referred to as a 100A 2-Pole Manual Changeover Knife Switch or Double Throw Disconnect Switch) is a heavy-duty manual electrical control device. It is primarily used to safely redirect power and switch loads between two different electrical sources, such as the main public utility grid and a backup generator.
Current Rating (100A): Built to handle high-current electrical loads, making it suitable for large residential homes, commercial spaces, or workshops with significant power consumption.
Double-Throw / Changeover Mechanism: Features a physical "knife-blade" lever mechanism that allows you to manually throw the switch between Source A (Grid) and Source B (Generator), preventing backfeeding and electrical hazards.
