EQUIPMENT DESCRIPTION
The automatic transfer switch is used for transferring electrical
load from a UTILITY (NORMAL) power source to a GENERATOR
(STANDBY) power source. Such a transfer of electrical loads
occurs automatically when the UTILITY power source has failed or
is substantially reduced and the GENERATOR source voltage and
frequency have reached an acceptable level. The transfer switch
prevents electrical feedback between two different power sources
(such as the UTILITY and GENERATOR sources) and, for that rea-
son, codes require it in all standby electric system installations.
This transfer switch is suitable for use as service entrance equip-
ment.
The GenReady transfer switch is designed to operate in conjunc-
tion with an air-cooled or R-panel series (liquid cooled) control
panel used on Generac generators. Utility voltage, automatic
transfer switch operation and sequence delays are controlled by
the control panel on the generator. The AUTO/OFF/MANUAL switch
must be in the AUTO position for automatic operation of the trans-
fer switch mechanism.
Utility voltage is monitored by the control panel. When the Utility
voltage drops below a preset value the generator will start and run.
After a warm up period, the transfer switch mechanism will turn off
the Utility supply and turn on the Generator switch connecting the
customer load to the Generator supply.
The Utility voltage is continuously monitored by the control panel.
When the voltage is above a preset value, the Return to Utility timer
is initiated. When this timer expires, the transfer mechanism will
turn off the Generator switch and turn on the Utility switch con-
necting the customer load to the Utility supply.

GENREADY™ BASIC LOAD CENTER
200A Main Circuit Breaker•
125A Circuit Breaker (Lower panel Utility feed).•
125A Lower Panel Circuit Switch•
To make this Load center into a transfer switch mechanism will
require the installation of an EZ Transfer operator. This can be
installed in the field at the time of installation or at a later date.

125A Circuit Breaker (Lower panel Utility feed).•
(2) 125A Lower Panel Circuit Switch•
15A, 2-pole circuit breaker for Utility sensing•
EZ Transfer™ Operator plus field installation kit components.•
GenReady Basic GenReady Advanced GenReady Complete
The GenReady load center is installed
without the EZ Transfer operator. It
replaces the home’s main load center.
This option will save the homeowner
thousands in upgrade costs when a
generator is installed.
The GenReady load center is installed
with the EZ Transfer operator. All
fuel and electrical lines (contractor
supplied) are installed to the planned
generator site along with the gen-
erator pad (if required). The home is
completely wired and ready for the
addition of a generator in the future.
Everything included in the GenReady
Advanced level is installed along
with an automatic standby generator.
The home’s selected circuits will be
backed up by generator power when-
ever the utility is lost.
