Generac Power Systems PowerPact 6561 Installation Notes page 5

Transfer Switches
 The Whole-House Transfer Switch amperage must be equal to or greater than the generator output or
service amperage, whichever is greater.
 Air-cooled Generators 6 to 22kW will put out 25 to 91.6 Amps.
 Generac's are smart generators with dumb switches.
 That means all the line sensing is done on the generator control board; the generator tells the switch
when to transfer power.
 On other brands, the switch has the brains and all the generator does is turn on or off.
 If you absolutely have to use another switch, there is a super-secret code to punch into the controller
that will let the generator run on a 2- wire start, but it probably voids the warranty.
GenReady Panel
 Used in New Construction or Service upgrades.
 It replaces the Main Panel in the house.
 It's a 200 Amp service with a 125 Amp Transfer Switch.
 There is a built-in transfer switch in the middle of the panel.
 You have 10 non-protected circuits on the top of the panel and 18 to 30 protected circuits
(with tandem breakers) on the bottom of the panel.
RTSY/RTST/RTSW /RTSB Switches – Whole House
 The RTSY/T/W Switch comes in 100, 150, 200, 300, and 400A versions. RTSB is 200A only
(Synergy)
 The RTSW switch will replace the Y/T switches Fall 2015. It will have built in Loadshedding
for four Air-conditioners.The RTSB comes with Fast Loadshed for Synergy Generator, all 9/10kW 2HP
loads must be shed.

The switches all have a service disconnect breaker in them.
RTG EZ Switches – Selected Circuits



and a 2-foot whip to the main panel box.
There is a NEW RTG16EZA3 Nema-3R switch. It has no whips.
RTSR/RTSP/RTSC /RSTI Non Service Switches
 The RTSC switch is the same as the RTSW switch except it does NOT have a Service Entrance
Breaker or internal cover. It will replace the R/P switches Fall 2015.
 It comes in 100, 200, 400, 600, and 800 Amp Switches.
 RTSI is 200A only (Synergy Canadian)
10 and 12 Circuit 50A can be flush mounted.
16 Circuit 100A is panel mounted.
All have:
a 30-foot whip from the switch to the outside wall,
a 5-foot whip from the connection box to the Genset,
