With built-in 16 circuit priority load center, the Power Manager LTS is designed to allow the most efficient use of a standby generator by monitoring and managing the backed-up, selected, and non-selected circuits. If generator approaches overload condition, the non-selected circuits are cycled off, allowing the selected circuits to remain powered. * Switch is designed to operate with Generac digital controls on air-cooled and liquid-cooled generators from 20 kW through 48 kW * Meets 2008 NEC standards * Service entrance rated at 200 Amps * Housed in aluminum NEMA 3R outdoor-rated enclosure
