Generac has several power transfer product lines for use with their standby generators. Each of these can be selected by clicking on the above boxes. Each type is also described below to help you decide which is best for your application.


Generac’s EZ Switch is an automatic transfer switch and distributed load center that backs up selected circuits for essential circuit coverage. Pre-wired for the easiest and least expensive installation on the market, they are an excellent value when whole house coverage is unnecessary.

Features & Benefits:
  • Each of these switches is rated at 100 amps
  • Available in 10, 12, 14 or 16 circuits
  • 30 ft. pre-wired conduit connects transfer switch to external box
  • 2 ft. pre-wired conduit for moving circuits from the main panel to the transfer switch
  • Pre-wired external connection box with weatherproof conduit for generator connections
  • NEMA 1 enclosure

RTS Series Transfer Switch - Click Here For Single Phase - Click Here For 3-Phase

With the RTS transfer switch, you can choose to cover every circuit all the time or only essential circuits depending upon the generator with which it is paired. RTS open transition transfer switches are ideal for residential, commercial and light industrial applications.

Features & Benefits:
  • Standard RTS transfer switches feature NEMA 3R enclosures for indoor or outdoor use.
  • 100 - 800 Amp, 3-phase, non-service rated
  • 600 - 800 Amp, single phase, non-service rated
  • Nema 3R rated rugged steel enclosures
  • Designed to operate with the digital control on air-cooled generators and the Generac R200 or Nexus controller used on liquid-cooled QT series gaseous generators from 22- 150 kW


Get more coverage from a smaller generator paired with the load shedding capabilities of the Nexus LTS transfer switch, the answer when more than six large loads need to be managed. The Nexus LTS is designed to allow for the most efficient use of the generator by monitoring and managing the backed up essential and non-essential circuits. If the generator approaches overload condition, the non-essential circuits are cycled off, allowing essential circuits to remain powered. It features a built-in, 16-circuit priority load center, a main contactor that protects the essential circuits and a secondary contactor that protects non-essential circuits.

Features & Benefits:
  • 200 Amp
  • Service-entrance rated
  • Aluminum NEMA 3R outdoor-rated enclosure has a side-opening hinged cover.

NEXUS SMART SWITCH - Click For Non Service Rated - Click For Service Entrance Rated

The Nexus Smart Switch is the smartest transfer switch on the market. Engineered with Generac's Digital Load Management (DLM) technology, it allows for more coverage with a smaller generator through smart load management. This advanced load shedding technology is standard, unlike competitive models that require additional hardware and investment to add a load management option. The Nexus Smart Switch has the ability to manage two air conditioners without adding additional components or cost. Gain even more flexibility by adding up to four individual DLM Modules for added load management.

Features & Benefits:
  • Intelligently manage up to six large, high demand loads
  • Depending on the size of the generator in the system, this switch can cover every circuit all the time for whole house coverage or provide managed whole house coverage when paired with a smaller generator.
  • 100 - 400 Amp, non-service rated, 1Ř, NEMA 3R enclosure
  • 100 - 400 Amp, service rated, 1Ř, NEMA 3R aluminum enclosure

GenReady Load Centers

New home construction or renovations with electrical upgrades are the ideal time to install Generac's GenReady Load Center. Because it's a hybrid electrical distribution panel combined with the transfer switch, you will enjoy substantial savings on installation and a simplified generator system. The advanced engineering of the GenReady Load Center replaces the home's main circuit panel and incorporates the automatic transfer switch, in the form of the EZ Transfer Operator, with the emergency panel. All power switching is handled within one unit, so it becomes a hybrid circuit panel capable of separating out only the electrical circuits chosen to be covered during a power outage.

Features & Benefits:
  • One circuit box replaces traditional two and three box setups, saving on installation costs and minimizing wallspace requirements
  • 40 circuit capacity with the use of tandem breakers
  • Dimensions same as a standard 42-circuit main load center
  • Compatible with generators rated up to 125 Amps/30 kW
  • Both NEMA 1 and NEMA 3R enclosures available
  • Accomodates Siemens, SquareD and GE 1" breakers
