Features

  • WHOLE-HOME AUTOMATIC POWER TRANSFER: Monitors utility voltage around the clock and transfers your entire 200A residential electrical service to standby generator power automatically during an outage no manual switching, no delay, no action needed
  • SERVICE ENTRANCE RATED WITH OPEN-TRANSITION SWITCHING: Rated for 200A at 120/240V single phase, the open-transition mechanism fully disconnects utility power before connecting generator power, physically preventing dangerous backfeed into the grid
  • COVERS FULL 200A RESIDENTIAL SERVICE INCLUDING 240V LOADS: Handles well pumps, electric dryers, central air conditioning, and other high-draw appliances simultaneously; add Generac Smart Management Modules to prioritize and protect your generator
  • INTEGRATED BROWNOUT PROTECTION AND HARDENED CONTROL MODULE: Monitors for harmful voltage disturbances including brownouts and automatically manages transfer timing, ensuring consistent system performance during degraded grid conditions
  • NEMA 3R ALUMINUM ENCLOSURE RATED FOR INDOOR OR OUTDOOR INSTALLATION: Corrosion-resistant aluminum housing with electrostatically applied baked powder paint withstands rain, snow, ice, and debris dimensions are 13.5" wide 6.5" deep 30" tall
  • COMPATIBLE WITH GFCI AND AFCI BREAKERS: Multi-listed for use with standard, tandem, GFCI, and AFCI breakers from Siemens, Eaton, and Square D, so most existing branch circuit breakers do not need to be replaced during installation
  • FAST-MOUNT ENCLOSURE SYSTEM REDUCES INSTALLATION TIME: Innovative hanging system allows professional installers to mount and position the enclosure faster on common residential surfaces, helping reduce overall labor time and installation cost
  • 5-YEAR WARRANTY WITH LICENSED ELECTRICIAN INSTALLATION REQUIRED: Backed by a 5-year limited warranty; service entrance installation must be performed by a licensed electrician per NEC Article 702 power inlet box and cord are not included

Description

The Generac 9952 (model G0099520) is a 200A open-transition service entrance rated automatic transfer switch built for whole-home standby power protection. Paired with single-phase Generac standby generators running Evolution or Power Zone 200 controllers, this switch monitors your utility supply continuously and transfers your full 200A electrical load automatically the moment grid power fails — then returns to utility power automatically when it is restored. Do you need a 200A switch? Match the switch amperage to your home's main electrical service rating. A 200A service entrance switch is the correct fit for homes with 200A service and handles both 120V and 240V loads simultaneously, including well pumps, electric dryers, HVAC systems, and refrigerators — with no circuit-by-circuit selection required. How backfeed is physically prevented: The open-transition design creates a hard mechanical break, fully disconnecting utility power before the generator connection is made. This physical sequencing eliminates the possibility of backfeed into the power grid and protects utility workers during an outage. This is different from an interlock kit, which mechanically prevents both breakers from being on simultaneously but requires manual operation; this switch handles all transfer automatically. GFCI and AFCI compatibility: Multi-listed for use with standard, GFCI, and AFCI breakers from Siemens, Eaton, and Square D, so existing breakers typically do not require replacement. Expandable load management: Generac Smart Management Modules can be added to shed lower- priority loads before your generator reaches its capacity limit. Installation note: Service entrance installation requires a licensed electrician per NEC Article 702. This switch is designed for Generac standby generators and does not include a power inlet box or connecting cord. For whole-home surge protection, see model G0099530. Backed by a 5-year limited warranty. 24/7 U.S.-based support from Waukesha, WI.

  • Worked as described, rough handling in delivery
Style: 200-Amp
Worked as described at competitive price point. Unfortunately had damage to upper corner like it had been dropped. We didn’t have enough time to replace the unit to stay on schedule for installation. Hopefully in the future Amazon can handle these expensive products with more care
