The Generac RXG42SHA1 is a 200‑amp automatic transfer switch featuring an integrated 42‑circuit load center, engineered to deliver reliable, whole‑home backup power distribution for residential standby generator systems. Designed for 120/240‑volt single‑phase applications, this switch continuously monitors utility power and automatically transfers electrical loads to generator power the moment an outage occurs. When utility service is restored, the RXG42SHA1 safely returns the home to normal operation without requiring homeowner intervention.
Its built‑in 42‑circuit breaker panel provides extensive load‑management flexibility, allowing installers to designate essential and non‑essential circuits for optimized generator performance. This makes the RXG42SHA1 an ideal solution for whole‑home or large partial‑home backup configurations where capacity, organization, and clean wiring are priorities.
Housed in a durable NEMA 3R enclosure, the RXG42SHA1 supports both indoor and outdoor installation, offering versatility across a wide range of residential layouts. Heavy‑duty contactors and robust electronic controls ensure long‑term reliability, consistent switching performance, and dependable operation in demanding environments.
