Reliance Controls vs Generac Transfer Switch Specs
Power capacity
Edge: Generac 100 Amp Automatic Transfer Switch
The Reliance Controls 31410CRK Pro/Tran is rated for 30 amps with a maximum running wattage of 7,500 watts. This kit supports up to ten single-pole circuits or five double-pole circuits. It is designed for smaller generator setups and limited circuitry needs. In contrast, the Generac 100 Amp Legacy Transfer Switch handles a 100-amp service rating. It supports up to 24,000 watts across your entire home panel. This higher capacity allows you to power 240-volt loads like well pumps and dryers. The Generac unit backs up the whole panel, while the Reliance unit covers a specific set of circuits.
Automation level
Edge: Generac 100 Amp Automatic Transfer Switch
The Reliance Controls transfer switch is a manual kit. You must physically connect your generator to the included 18-inch flexible conduit whip and flip the switch to transfer power. This requires hands-on action every time an outage occurs. The Generac unit is fully automatic. It senses utility power failures and starts your compatible Generac generator to transfer power automatically. This open transition switching mechanically isolates utility and generator power to prevent backfeed. You do not need to be present to start the process, making it a more convenient option for whole-home backup.
HVAC management
Edge: Generac 100 Amp Automatic Transfer Switch
The Reliance Controls switch does not include specialized climate control features. It simply distributes power to the selected circuits. The Generac transfer switch includes a built-in Smart AC Module. This module manages up to four HVAC loads automatically. It sequences air conditioning or heating loads without requiring extra hardware. If you need more circuit control, optional Smart Management Modules are available. This feature helps balance power demands during long outages, ensuring your most critical climate control systems remain operational without overloading the generator.
Enclosure build
Edge: Reliance Controls 30 Amp 10-Circuit Transfer Switch
The Reliance Controls unit features a rugged, powder-coated steel cabinet. It measures 4.5 inches wide, 7 inches long, and 13.8 inches high, weighing 15 pounds. It includes six combination knockouts for wiring. The Generac switch uses a NEMA 3R aluminum enclosure. It measures 7.09 inches wide, 14.6 inches long, and 20 inches high, weighing 21.9 pounds. The aluminum housing resists corrosion and moisture, making it suitable for outdoor weather exposure. Both units offer durable protection, but the Generac model provides a larger, weather-rated aluminum shell.
Installation requirements
Edge: Reliance Controls 30 Amp 10-Circuit Transfer Switch
The Reliance Controls kit is designed for reliable-fast installation in both residential and commercial applications. It attaches easily to the load center using the included conduit whip. The Generac Legacy Transfer Switch has a service entrance rating. This means it functions as your main service disconnect and ties directly into utility service. Local code requires a licensed electrician and a permit for this installation. You cannot install the Generac unit yourself. The Reliance unit is more accessible for DIY installation, while the Generac unit mandates professional service.

Frequently asked questions
Is a Generac automatic transfer switch better than a Reliance manual one?
The choice depends on your need for automation. The Generac RXSW100A3 operates automatically, switching power without manual intervention. It is designed for whole-home backup with 100-amp capacity. The Reliance Controls 31410CRK is a manual unit. You must switch it by hand. This makes it suitable for smaller generators and essential circuits only.
What is the maximum amperage for the Reliance Controls transfer switch?
The Reliance Controls unit is rated for 30 amps. This lower amperage suits smaller portable generators. It supports ten single-pole circuits or five double-pole circuits. This capacity protects ten specific home circuits. It is not designed for whole-home backup like higher-amperage automatic systems.
Does the Generac transfer switch require a specific generator brand?
The Generac 100 Amp Automatic Transfer Switch is designed to pair with Generac standby generators. It features integrated HVAC management for whole-home backup. While it isolates utility power, it is optimized for the Generac ecosystem. This setup suits homeowners wanting automatic operation and higher capacity.
How many circuits can the Reliance Controls switch handle?
The Reliance Controls 31410CRK supports up to ten circuits. You can configure these as ten single-pole or five double-pole circuits. This limit fits homeowners with smaller generators. It allows you to protect essential loads like lights, refrigerators, and sump pumps during an outage.
What are the physical dimensions of the Generac transfer switch?
The Generac RXSW100A3 measures 20 inches in height, 14.6 inches in length, and 7.09 inches in width. It weighs 21.9 pounds. These dimensions accommodate its 100-amp automatic operation. The unit is intended for outdoor installation and includes no finish on the casing.
Is the Reliance Controls unit suitable for large homes?
This unit is best for homes with smaller generators. Its 30-amp rating limits the total power available. It protects ten specific circuits rather than the whole house. If you need automatic whole-home backup or higher capacity, the 100-amp Generac option is more appropriate for larger electrical loads.
What is the weight difference between the two transfer switches?
The Reliance Controls 31410CRK weighs 15 pounds. The Generac RXSW100A3 weighs 21.9 pounds. The Generac unit is heavier due to its automatic mechanism and higher 100-amp capacity. The Reliance unit is lighter, reflecting its manual operation and 30-amp rating for smaller power needs.
