Do NOT modify any equipment.
Do NOT install anything that is not to code.
Any $$ you think you will save on your install by modifying equipment, NOT following the recommended
installation procedures, or going against local code, may be a safety issue for your customer, may void
warranties, and may not pass required inspections.
A Generator installation should be a very easy job. Just follow the  instructions, local
requirements, and you should have no problems.
Read ALL Manuals and Install Guides before attempting an install.
Permits and Applications
The Local Code Office has the final say on your install.
All Towns have different requirements. Check with the local code office before submitting a final quote
to your customer.
Brighton and Perinton are two of the more restrictive towns in our area.
Attached are examples of permit for the Town of Perinton and, if you have a NatGas installation
examples of the required RG&E Forms. NYSEG & Other Utilities may have different requirements.

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.
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
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,
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)

RTSJ200A3 Switch
This switch is basically a combination of the RTSY200A3 and the RTG16EZA1 switches.
It's a 200-Amp Whole House Service Entrance Switch that load sheds to a 16-circuit
priority load center. This Switch will become obsolete in 2015.
New 2015 "HomeLink" Upgradable Manual Transfer Switches
Manual version of the 8 Cir RTG Switch. It is 6 to 10 Circuit Manual Transfer

Also a Ground/ Neutral Bar Kit.
Delivery
You can pick up for free at our Rochester C&M Forwarding Warehouse, or have your system delivered.
There is a delivery charge from our Rochester Warehouse, or if we direct ship from the factory there
is no charge for delivery. If you are in the Rochester area we also have a cart to rent (if you are
local) -- try before you buy.
Safety Tip for the Generac Generator Cart - Use the long strap from a ratchet tie down. Hook the
end to the Generator Pad, when the unit is raised tie the other end off to the cart handle. This will
prevent the handle from flipping over accidently.
The PowerPact may be moved with a 2 wheeled cart. Leave it on the pallet & place cardboard
between the generator & cart. At the site the generator must be lifted off the pallet NOT dragged off.

Site Selection and Preparation
This section can be found on page 10 of the Installation Guidelines for Air-cooled Generators.
Location of Generator
•Air-cooled generators should be located as close as possible to the transfer switch and fuel supply.
•There must be 5 feet of clearance around the gas meter.
•Leave adequate room around the area for service access (check local code),
•Place high enough to keep rising water from reaching the generator.
Air Circulation Requirements
•Choose an open space that will provide unobstructed air flow.
•Place the unit so air vents won't become clogged with leaves, grass, vegetation, snow, or debris.
•Make sure exhaust fumes will not enter the building through eaves, windows, ventilation fans, or other air
intakes.
•Install the generator, in its protective enclosure, outdoors, where adequate cooling and ventilating air is
always available.
Not only too close to a window but how about three windows! Maybe a few more plants and you wo
Mounting
•The generator comes with a composite pad.
•You can place the generator with the composite pad on pea gravel or a concrete pad.
•Check local codes to see what type of base is required.
Note: Whatever mounting you choose, the generator must be level within ½”.

Generac doesn't recommend a wood box platform.
Why waste a perfectly good pallet?
HPS found this one - Nice Pad.

- The shed that this generator is mounted in greatly reduces the noise level.
NO…..NO……NO!!!!!!!
Another one found by HPS - Needs more air flow
That's better
