AUTOMATIC TRANSFER SWITCHES
POWERMASTER™
LOAD SHEDDING
DEVICE
Create priority loads to ensure
home comfort during a power
loss! The PowerMaster is a load
shedding device that allows
a home owner to operate two
large electrical loads instead
of only one large appliance.
Examples of this include a
central air conditioner or an
electrical hot water heater. When
the priority load is running,
the PowerMaster will lock out
the other piece of equipment,
keeping it from turning on until
the demand is satisfied for the
priority load. After the demand is
satisfied, the PowerMaster allows
the secondary load to come
online and operate.

AUTOMATIC TRANSFER SWITCHES
As a part of the generator system, the transfer switch transfers the electrical load onto the
generator when power fails. When utility voltage returns, the transfer switch safely returns
circuit coverage back to the utility.
DistributedLoadCenter
Generac offers three models of automatic transfer switches for homeowners who
choose to back up selected circuits rather than the entire house. Pre-wired load
center models are available with a choice of 8, 10, 12, 14 or 16-circuits.
Generac makes installation easy and inexpensive.
All distributed load center models include:

PowerManager™LoadSheddingTransferSwitch
The PowerManager LTS is designed to allow the most efficient use of the generator by
monitoring and managing the backed up selected and non-selected circuits.
If the generator approaches overload condition, the non-selected circuits are
cycled off, allowing the selected circuits to remain powered. This switch is
designed to operate with the digital controls that are used on single-phase
air-cooled and liquid-cooled generators from 17 kW through 48 kW.

RTS transfer switches are designed for a wide variety of applications that
require up to 400 Amps. The RTS is integrated with the R-Series digital
controller and operates only with standby generators thru 60 kW.
NEMA 3R (outdoor rated) enclosures are standard.
RTS-N (Single and Three-Phase)
Use RTS-N models for custom installations or with
applications that require a sub-panel.
