Electrical disconnects are also call ‘Safety Switches’. They are used to disconnect, interrupt, and/or isolate current flow within a circuit. They are basically circuit interrupters for both AC and/or DC circuits; and are important to all solar systems. Load centers are used to divide and/or combine various circuits within a system. They use circuit protection devices to protect the wiring within each circuit. They can be small and simple with limited power handling capacity, up to large and sophisticated, with high-power handling capability. They can be for AC or DC circuits of varying Voltages
