A fireman’s switch is a safety device used by fire and rescue personnel to disconnect solar panels or battery banks from the building’s electrical panel. The aim is to ensure that there is no potential in the wires, reducing the risk of electric shocks and fires during rescue operations. The switch is used to quickly and easily disconnect the electrical system from solar cells or battery banks and isolate them from the property’s main power source. This is particularly important because PV systems can continue to generate electricity even after the property has been disconnected from the main grid, which can increase the risk of accidents if not properly insulated.
