Reliance Controls Corporation specializes in solutions for portable generator power integration, primarily offering transfer switches and related accessories. When referring to "Control Units," they are generally talking about the core mechanism that allows a portable generator to safely and efficiently power specific circuits in a building during an outage.

Product Details

Functionality: Reliance Control Units (specifically, their transfer switches) enable a user to manually or, in some cases, automatically switch designated electrical circuits from utility power to a connected portable generator. This prevents dangerous "backfeeding" of electricity into the utility grid, protecting utility workers and the home's electrical system.
Types:

Manual Transfer Switches (Pro/Tran® Series): These are the most common "control units" from Reliance. They come in various circuit capacities (e.g., 4, 6, 8, 10 circuits) and amperage ratings. Users manually flip switches to transfer power for selected circuits.
Automatic Transfer Switches (ATS): While less common for their portable generator solutions, Reliance also offers some ATS solutions that can detect a power outage and automatically start a generator and transfer the load.
Transfer Panels (Panel/Link® Series): These are essentially larger, more integrated transfer switch solutions that can handle more circuits and higher wattage generators, sometimes acting as subpanels.

Key Features:

Circuit Protection: Built-in circuit breakers protect individual circuits from overloads.
Safe Transfer Mechanism: Designed to prevent backfeeding into the utility lines.
Indicators: Often include indicator lights (e.g., "utility power," "generator power").
Durability: Housed in robust enclosures, often NEMA 3R rated for outdoor use (depending on the model).
Pre-wired Options: Many kits come pre-wired for easier installation.

Product Parameters

Amperage Ratings: Typically range from 15 Amps to 200 Amps, depending on the specific model and number of circuits. Common ratings include 20A, 30A, 50A.
Voltage: Primarily 120V AC or 120/240V AC, suitable for standard residential and light commercial electrical systems.
Wattage Capacity: Rated for the maximum continuous running watts they can handle from a generator (e.g., 5,000 watts, 7,500 watts, 12,500 watts, up to 31.5 kW for larger transfer panels).
Number of Circuits: From 4 to 16 circuits (for manual transfer switches), or more for larger transfer panels.
Enclosure Type: Often NEMA 1 (indoor) or NEMA 3R (outdoor, rain-tight).
Certifications: UL Listed (Underwriter Laboratories) to standard 1008, meeting NEC (National Electrical Code) requirements.
Input Connection: Designed to connect to a compatible power inlet box for generator connection (e.g., L14-30, L14-50 receptacles).

Product Advantages

Safety: The primary advantage is the prevention of dangerous backfeeding, which protects both homeowners and utility workers.
Ease of Use: Manual transfer switches are generally straightforward to operate, even for homeowners.
Cost-Effective Backup Power: Provides a relatively affordable way to use a portable generator for home backup, compared to whole-house standby generators.
Reliability: Reliance Controls products are known for their sturdy construction and reliable performance during power outages.
NEC Compliance: Designed to meet National Electrical Code requirements, ensuring safe and legal installation.
Versatility: A range of models accommodates different generator sizes and the number of circuits needed for backup.

Important Considerations

Professional Installation: While some homeowners might be capable, it is highly recommended that Reliance Control Units (transfer switches) be installed by a qualified electrician to ensure safety and compliance with local electrical codes.
Generator Compatibility: Ensure the transfer switch's amperage and wattage ratings are compatible with your portable generator's output.
Circuit Selection: Carefully plan which essential circuits you want to power during an outage (e.g., furnace, refrigerator, lights, well pump).
Location: Choose an appropriate indoor or outdoor location for installation, considering the enclosure's NEMA rating.
Power Inlet Box: A compatible power inlet box is required to connect the generator to the transfer switch.
Load Management: Users must understand the total wattage capacity of their generator and the transfer switch to avoid overloading the system during an outage.

Product Applications

Residential Backup Power: The most common application, allowing homeowners to power essential circuits during utility outages using a portable generator.
Small Commercial Backup: Providing emergency power to critical circuits in small businesses, offices, or workshops.
Agricultural Use: Powering essential equipment like well pumps or lighting in barns during outages.
Temporary Power: For construction sites or events where a portable generator needs to be safely integrated into a temporary electrical system.
Off-Grid/Remote Cabins: Though less common than dedicated off-grid systems, some simpler setups might use these for managing generator input.
