What is a Multi-Breaker Interlock Kit?
In the realm of home energy management, particularly in situations requiring the switch from grid power to generator power, the initial load can pose significant challenges. For homeowners with multiple heavy-load appliances, such as separate AC units for different floors, managing this load during power transition is crucial to prevent generator stalls. The multi-breaker interlock kit, modified by Interlock Kit, plays a pivotal role in this scenario by blocking out a non-emergency higher-load appliance, thus limiting the start-up load indefinitely for a safer transition.
The Challenge of Initial Load on Generators
When emergency situations demand the switch from grid to generator power, the sudden load from multiple high-power appliances can overwhelm generators. This is particularly true in homes with more than one AC unit, where the simultaneous start-up load of these units can cause generator stalls, leaving homeowners without power when they need it most
The Multi-Breaker Interlock Kit Solution
A multi-breaker interlock kit is traditionally designed to facilitate a safe and code-compliant transition between grid power and a generator. However, with a simple yet effective modification, these kits can be adapted to manage the initial load more efficiently. By installing one of our Interlock Kits, that specifically blocks heavy load appliance or appliances, homeowners can prioritize essential loads and prevent the generator from being overloaded during start-up. A safe power transfer ensures that the things that matter most, like an AC unit or a refrigerator, can keep running in a time of need.
How a Multi-Breaker Interlock Kit Works
There are three important components of a multi-breaker interlock kit: interlock modification, load management and safety.
- Interlock Modification: The modification involves adjusting the original interlock kit to block out one or more breakers, such as those for upstairs AC/Heat units. This ensures these units remain off during the initial power switch, reducing the immediate demand on the generator.
- Load Management: By controlling which circuits are energized during the transition, our modified interlock kit allows for a gradual increase in load. This can prevent the sudden surge that typically leads to a generator stalling.
- Safety and Compliance: These modifications are designed to maintain safety and compliance with electrical codes, ensuring that the interlock still functions as a manual transfer switch but with enhanced load management capabilities.
Benefits for Homeowners
Still wondering if this may be the solution you are looking for? There are many benefits for homeowners and business owners who have a multi-break interlock kit for your generator. Safety is the most important component, and our kits all meet the criteria. But specifically, how are multi-breaker interlock kits a sound investment?
- Prevention of Generator Stall: By limiting the start-up load, homeowners can avoid the inconvenience and potential danger of a generator stall during critical times.
- Increased Efficiency: Managing the load more effectively can also help improve the efficiency of the generator, potentially extending its lifespan and reducing fuel consumption.
- Customized Load Management: Homeowners can choose which circuits to prioritize, ensuring that essential services remain powered while non-essential loads aretemporarily blocked.
Customized load management
When a homeowner is choosing a breaker(s) to be considered non-essential during a power outage while running on a generator, several key considerations come into play to ensure safety, efficiency, and comfort. These considerations help in prioritizing the use of limited generator power for essential needs and services. Here are some appliances and their required load (amperes) for your consideration:
- Central Air Conditioning Systems: 15-60 amps. Central AC units are one of the most power-intensive appliances. This demand is compounded in homes with multiple units that are cooling different parts of the home
- Electric Vehicle (EV) Chargers: 15-80 amps, depending on the type (Level 1, Level 2, or DC Fast Charge) and the specific vehicle requirements. Level 2 chargers, common in homes, typically use between 20 to 50 amps.
- Electric Ranges: 30-50 amps. Electric stoves and ovens require substantial power, particularly when multiple burners and the oven are used simultaneously.
- Clothes Dryers: 20-30 amps. Electric dryers, especially those with high heat settings and larger capacity, draw significant electricity.
- Water Heaters: 20-30 amps for electric models. Electric water heaters use a lot of power to quickly heat water in the tank.
- Heat Pumps: 15-60 amps, depending on size and whether it’s for heating, cooling, or a combination of both.
- Hot Tubs and Spas: 40-60 amps. The heating elements and pumps in hot tubs require a lot of power, especially for larger models.
- Welders: For home use, typically 20-50 amps, but this can vary widely based on the type of welding being done.
Installation Considerations
While the modification offers significant benefits, it’s essential to work with a professional for installation. This ensures that the interlock kit is installed according to its code-compliant design.
Is a Multi-Breaker Kit Worth It?
The modified multi-breaker interlock kit represents a simple yet innovative solution to a common problem faced by homeowners during power outages. By Limiting the start-up load through strategic blocking of certain breakers, such as those for AC units, it ensures a safer and more reliable transition to emergency power. As we continue to seek ways to enhance home energy management, such modifications highlight the importance of adaptability and safety in our systems.
