Generac 200 Amp Next Gen Automatic Generator Transfer Switch | Non Integrated Surge Protection Device, Non Service Entrance Rated, Hardened Fuse Control Module

The Generac 200A Non-Service Entrance Automatic Transfer Switch is engineered for homes with a standard 200-amp main service panel that require seamless, whole-home backup power from a compatible Generac Home Standby or Guardian generator. The generator's Evolution™ or Power Zone™ 200 controller handles all power sensing, timing, and transfer commands automatically — the moment utility power drops or degrades, the system responds without any manual intervention. At 200 amps on a 120/240V single-phase system, this switch transfers your entire home's electrical load in a single operation. It supports simultaneous 120V and 240V circuits including central air conditioning, well pumps, sump pumps, refrigerators, electric ranges, and lighting — no circuit-by-circuit selection required. Buyers looking to back up only a handful of circuits should evaluate a circuit-based manual transfer switch; buyers with a Generac whole-home standby system will find this the correct and complete solution. Unlike an interlock kit — which physically blocks two breakers from being on simultaneously in your existing panel — a dedicated automatic transfer switch like this unit provides a fully isolated, code-compliant transfer path with a mechanical interlock that makes simultaneous connection of utility and generator power physically impossible. This satisfies NEC Article 702 requirements and protects utility workers from backfed voltage during outages. The NEMA 3R aluminum enclosure carries an electrostatically applied, baked powder-coat finish rated for both indoor and outdoor installation, resisting corrosion from rain, snow, ice, and environmental debris. The hardened control module includes integrated brownout and surge protection to ensure the switch performs reliably even during unstable utility conditions. Installation requires licensed electrical work at the main service panel. Backed by a 5-year limited warranty with 24/7/365 support from Generac's Wisconsin-based team.

• WHOLE-HOME AUTOMATIC STANDBY BACKUP: Monitors utility power continuously and transfers your entire 200-amp home electrical load to a compatible Generac standby generator automatically, with no manual action needed
• HARDENED CONTROL WITH BROWNOUT PROTECTION: The integrated control module withstands brownouts and power disturbances that cause false transfers, keeping your backup system responsive and consistently reliable
• 200-AMP FULL-PANEL COVERAGE FOR 120V AND 240V LOADS: Rated at 200A on a 120/240V single-phase system, supporting simultaneous operation of HVAC, well pumps, electric ranges, and whole-home circuits
• NEMA 3R ENCLOSURE RATED FOR INDOOR OR OUTDOOR MOUNTING: The aluminum corrosion-resistant enclosure with electrostatically applied powder-coat finish is built to deflect rain, snow, ice, and debris year-round
• MECHANICAL INTERLOCK ELIMINATES BACKFEED RISK: Utility and generator power sources are physically prevented from connecting simultaneously, satisfying NEC Article 702 requirements for standby power installations
• DESIGNED FOR GENERAC HOME STANDBY AND GUARDIAN GENERATORS: Works with single-phase Generac standby systems using Evolution or Power Zone 200 controllers for fully automated sensing, timing, and transfer
• FAST-MOUNT SYSTEM REDUCES INSTALLATION TIME: An innovative enclosure fast-mount hanging system on select models saves professional installers 30 or more minutes of setup time, lowering overall installation costs
• 5-YEAR WARRANTY WITH 24/7 WISCONSIN-BASED SUPPORT: Protected by a 5-year limited warranty covering the integrated surge protection device and backed by Generac's round-the-clock customer support team
