Generac 200A Automatic Transfer Switch – Service Entrance Rated (No SPD)

Overview & Function

The Generac 200A service-entrance automatic transfer switch manages utility-to-generator transitions for whole-house standby protection. This no-surge-protection version delivers code-compliant transfer without the cost of an integrated SPD. It is a practical value choice where separate surge mitigation already exists or is not specified. ### Fitment & Compatibility Designed as a replacement for RXSW200A3, it fits 200A service-entrance standby installations using compatible Generac generators. Differentiate from SPD-equipped siblings when surge suppression is mandated by specification. Verify service rating, enclosure type, and generator pairing with a licensed electrician before purchase. ### Technical Construction & Specifications This OEM Generac ATS is rated 200A service entrance for automatic standby duty. The assembly omits surge protection circuitry while retaining factory transfer controls and switching components. Construction supports safe automatic transfer, retransfer, and exercise coordination in residential standby applications. ### Installation & Maintenance Guidelines Professional installation with permits and utility coordination is required for service-entrance equipment. Mount per code clearances, torque conductors to specification, and label service disconnects clearly. Register the warranty and schedule annual inspections with generator exercise verification for dependable operation.
