24 Circuit Load Center SE Automatic Transfer Switch NEMA 1 UL
Generac 100 Amp 24-Circuit Load Center Automatic Transfer Switch SE ATS – NEMA 1 UL
The Generac 100 Amp 24-Circuit Load Center Automatic Transfer Switch is designed to provide automatic power transfer between utility electricity and a compatible standby generator. Combining a 100-amp service-entrance-rated transfer switch with an integrated 24-circuit load center, this unit provides a convenient way to manage backup power circuits from a single enclosure.
Its 120/240-volt single-phase configuration is suited to compatible residential and light-commercial electrical systems, while the NEMA 1 enclosure is intended for indoor installations. This version is UL listed and not CUL listed, making it important to verify certification requirements for the intended installation location.
Key Features
100-amp automatic transfer switch for compatible standby generator systems.
Integrated 24-circuit load center for streamlined electrical distribution.
Service-entrance rated (SE) design for applicable installations.
Designed for 120/240V single-phase electrical systems.
NEMA 1 enclosure intended for indoor use.
UL listed.
Not CUL listed.
Automatically transfers supported electrical loads between utility and generator power.
Automatically returns loads to utility power when normal service is restored.
Combines transfer-switch and load-center functions in one enclosure.
Designed for use with compatible Generac standby generators.
Integrated 24-Circuit Load Center
One of the main advantages of this configuration is the integrated 24-circuit load center.
Rather than requiring a separate load center and transfer-switch enclosure for the applicable installation, the combined design provides a centralized location for managing supported electrical circuits.
The 24-circuit capacity allows the installer to organize multiple branch circuits within the load center according to the requirements of the electrical system and generator.
The actual number of circuits that can operate simultaneously during an outage depends on generator capacity, circuit ratings, load calculations, and the installation configuration.
Automatic Transfer Operation
During normal operation, the electrical system is supplied by utility power.
When the transfer switch detects a utility outage or an unacceptable utility condition, the compatible standby generator can start. Once generator power reaches the required operating conditions, the transfer switch automatically transfers the supported electrical load to the generator.
When utility power returns and stabilizes, the switch automatically transfers the load back to the utility source. The generator can then complete its normal shutdown sequence.
This automatic operation helps maintain selected electrical circuits without requiring the user to manually change the power source.
100-Amp Service-Entrance Rated Design
The 100-amp service-entrance-rated configuration is intended for installations where the transfer switch is incorporated into the electrical service equipment, subject to the manufacturer's requirements and applicable electrical codes.
Service-entrance installations have specific requirements concerning disconnecting means, grounding, bonding, overcurrent protection, and utility connections. These requirements should be evaluated by a qualified electrical professional before installation.
The 100-amp rating applies to the transfer equipment and should not be interpreted as the generator's available output. The generator must be properly sized for the electrical loads that are expected to operate during an outage.
NEMA 1 Enclosure
The NEMA 1 enclosure is designed primarily for indoor applications.
It provides protection for the enclosed electrical components against incidental contact with the equipment and against limited amounts of falling dirt and similar indoor environmental exposure.
This is different from a weather-resistant outdoor enclosure. The installation location should therefore meet the manufacturer's environmental requirements.
UL Listed — Not CUL
This model is identified as UL listed and not CUL listed.
Customers and installers should verify that the certification carried by the specific transfer-switch model satisfies the electrical and regulatory requirements of the intended installation location.
Certification requirements can differ between jurisdictions, so the exact model documentation should be reviewed before purchase or installation.

Typical Applications
This Generac combination transfer switch and load center can be used in properly designed:
Residential standby generator installations
Homes requiring automatic backup-power transfer
Small commercial backup-power systems where approved
New generator installations
Electrical service upgrades
Standby generator replacement projects
Applications requiring an integrated transfer switch and load center
Benefits of the Integrated Design
Simplified Installation
Combining the transfer switch and load center can reduce the need for separate equipment in installations where this configuration is appropriate.
Organized Circuit Management
The integrated 24-circuit load center provides a centralized location for managing branch circuits.
Automatic Backup Power
The transfer switch automatically changes the connected electrical source from utility to generator when required.
Automatic Return to Utility
Once normal utility power is restored, the system automatically transfers the load back to the utility.
Indoor Installation
The NEMA 1 enclosure is suited to appropriate indoor electrical equipment locations.
Installation Considerations
Because this equipment forms part of a permanent electrical service, installation should be performed by a qualified electrician or appropriately licensed electrical professional.
Before installation, confirm:
The electrical service is compatible with the 100A, 120/240V single-phase configuration.
The standby generator is compatible with the transfer switch.
The generator has sufficient capacity for the intended backup loads.
The service-entrance configuration meets applicable electrical requirements.
The load center and branch-circuit arrangement are properly sized.
Grounding and bonding are correctly configured.
The indoor installation location meets NEMA 1 requirements.
UL listing is acceptable for the jurisdiction where the equipment will be installed.
Local electrical codes and Generac installation instructions are followed.
A Convenient Backup-Power Solution
The Generac 100 Amp 24-Circuit Load Center Automatic Transfer Switch SE ATS – NEMA 1 UL combines automatic generator transfer and electrical circuit distribution in a single indoor enclosure.
Its 100-amp service-entrance-rated design, 120/240V single-phase configuration, 24-circuit load center, NEMA 1 enclosure, and UL listing make it a practical choice for compatible standby-power installations.
For proper system performance and code compliance, the transfer switch should be matched to the specific Generac generator, electrical service, connected loads, circuit requirements, and certification requirements of the installation location.
