Overview & Function
This Generac 150A automatic transfer switch is service-entrance rated and includes integrated surge protection SPD. It is intended to manage automatic standby power transfer for single-phase services associated with Evolution and PowerZone 200 controllers.
Fitment & Compatibility
Designed for single-phase standby systems specifying 150A service-entrance transfer capability with integrated SPD. Verify utility service size, generator compatibility, controller model, and local code requirements against project plans. This 150A version differs from the 200A RXSW replacement model in amperage and application scope, not core SPD family.

Installation & Maintenance Guidelines
Plan freight handling for heavy electrical equipment and engage a licensed electrician for permits, service-entrance wiring, and commissioning per code and utility rules. De-energize services before work, follow Generac torque and grounding procedures, test transfer operation at startup, and register warranty. Inspect SPD status and connections periodically per maintenance schedule.
