Transfer Switches

Transfer switches make it happen. They separate the circuits from utility and switch over the emergency generator. Here the most often used types:

Essential Coverage:

EZ-Switch, the pre-wired transfer switch load center comboPre-wired Swich

  • Available in 10, 12, 14 or 16 circuits
  • 30 ft. pre-wired conduit connects transfer switch to external box for generator connections
  • 2 ft. pre-wired conduit for moving circuits from the main panel to the transfer switch
  • NEMA 1 enclosure,  Spec Sheet

GenReady Load Center including Transfer SwitchGenReady(tm) Load Center

The GenReady Load Center replaces the home’s main circuit panel and incorporates the automatic transfer switch. All power switching is handled within one unit.

  • 40 circuit capacity with the use of tandem breakers, Siemens, SquareD and GE 1″ 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
  • Spec Sheet

RTS Series Transfer SwitchRTS Series Transfer Switch:

Standard RTS transfer switches feature NEMA 3R enclosures for indoor or outdoor use.

  • 100 – 800 Amp, 3Ø, non-service rated
  • 600 – 800 Amp, 1Ø, non-service rated
  • Nema 3R rated rugged steel enclosures
  • Designed to operate with air or liquid-cooled generators up to 150 kW that are enabled with the Evolution or Nexus controller
  • 100 – 400 Spec Sheet , 600 – 800 Spec Sheet

Managed  and Whole House Coverage:

LTS Transfer Switch - smart switch with load sheddingLTS Switch

The LTS switch 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.

  • 200 Amp, Service-rated
  • Aluminum NEMA 3R outdoor-rated enclosure has a side-opening hinged cover.

Generac Smart Switch for Whole House Power CoverageGenerac Smart Switch

  • 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
  • 100 – 400 Amp, non-service rated, 1Ø, NEMA 3R enclosure
  • Spec Sheet

Power Management Module (PMM)

Generac Power Management Module (PMM) for Smart SwitchThe Digital Power Management system consists of two parts. The first is the PMM (Power Management Module) Starter Kit, which includes the easily field installed 24VAC transformer and the first 50 amp, 24VAC actuated PMM. The transformer must be installed in the NEMA 3R Smart Switches. The second is the PMM, a 50 amp, 24VAC actuated contactor housed in a NEMA 3R enclosure for indoor and outdoor installation applications.

Through the use of the PMMs in conjunction with any of the 100-800 amp, single phase switches, loads can be intelligently managed enabling the use of a smaller, more efficient generator system. Up to four PMMs can be used with a single switch.

  • Power Supply Source: Contactor module is supplied with 24VAC from the OPCB (Overload Prevention Control Board) in the transfer switch
  • Coil VA Inrush: 41, Coil VA Sealed: 6.5
  • Poles: 2, Voltages: 240VAC, Resistive Amps: 50, F/L Inductive Amps: 40
  • Locked Rotor Amps: 240@240V
