Real-Time Energy Monitoring
Tracking Energy Usage and Trends
Smart circuit breakers provide detailed, circuit-level data by continuously measuring voltage, current, power (kW), frequency, and total electricity consumption (kWh). This level of precision allows you to see exactly how much energy specific appliances - like your HVAC system, water heater, or EV charger - are consuming. The data is stored and displayed through apps that offer historical usage charts, making it simple to compare energy use across billing cycles and spot trends. By identifying high-consumption circuits, you can uncover inefficiencies and take steps to address them. This steady stream of real-time data puts you in control of your energy management.
"The EMCB's user interface can ultimately become a real-time energy dashboard allowing the utilities and the consumers themselves better understand when and how they use electricity. It's like putting your entire home on a FitBit." – Eaton Innovation Story
These systems also use advanced sensors and machine learning to detect unusual patterns. For instance, if an appliance starts drawing more power than usual or runs excessively, the system flags it, helping you catch potential equipment issues early.
Reducing Phantom Loads and Spikes
Beyond tracking, smart systems are designed to address inefficiencies, including phantom loads and sudden demand spikes. Phantom loads are the power consumed by devices in standby mode, and smart monitoring tools make it easy to identify these hidden energy drains. By reviewing a circuit-by-circuit breakdown, you can quickly determine which appliances are wasting energy unnecessarily. Many systems let you set power thresholds and send alerts if consumption spikes unexpectedly, allowing you to take immediate action - like remotely shutting off a circuit that was accidentally left on.
These systems can also prioritize energy use during peak demand or outages. For example, if you're relying on backup power, the system can automatically turn off nonessential circuits - like those powering pool pumps or dishwashers - while keeping critical appliances like refrigerators running. This ensures energy is used efficiently, extending backup power and reducing waste.
Remote Control and Automation
App-Based Circuit Management
Expanding on real-time monitoring, remote and automated control of your electrical panel helps cut down on energy waste. With apps like My Leviton, you can manage circuits directly from your smartphone. Need to turn off a specific circuit? Open the app, select the circuit, and tap to switch it on or off. You’ll get real-time updates on its status, and many systems even include LED indicators on the breaker itself, making it easier to see which circuits have been disabled remotely.
These apps also integrate with smart home systems, allowing you to manage breakers, EV chargers, solar panels, battery storage, and smart lighting - all from one convenient interface. This streamlined control simplifies energy management and lays the groundwork for broader automation throughout your home.
"Leviton continues to equip homeowners with the necessary insights to control their expenses and environmental impact, focused on meeting tomorrow's electrical needs via a single app for lighting, load control, and EV charging." – Justin Berghoff, Senior Director of Business Development & Product Management, Leviton
Automated Measures to Reduce Energy Waste
Automation takes energy management a step further by minimizing the need for manual adjustments. For instance, you can schedule circuits to run at specific times or on certain days, aligning energy-heavy appliances like water heaters or dishwashers to operate during off-peak hours - say, between 11:00 PM and 6:00 AM - when electricity rates are lower.
Beyond scheduling, smart breakers can automatically adjust during peak demand. They prioritize essential circuits - like refrigerators or medical equipment - by temporarily disabling non-critical loads, such as pool pumps or secondary HVAC systems. This ensures critical appliances stay powered during outages or high-demand periods.
Additionally, smart systems can detect anomalies, such as an HVAC system running longer than usual or a freezer that’s stopped working. These alerts allow you to address potential problems quickly, preventing both unnecessary energy use and costly repairs.
Load Balancing and Power Management
Dynamic Load Distribution
Smart breakers play a crucial role in managing your home's power by allowing you to classify circuits as either essential or non-essential through a convenient app. When your home nears its electrical capacity - or when it switches to backup power - the system automatically shuts off non-essential circuits, ensuring critical systems stay operational for longer periods.
This approach is especially helpful during peak electricity demand. Instead of risking an overloaded panel, smart breakers can temporarily cycle high-energy appliances like water heaters and HVAC systems. For instance, in 2016, Eaton and EPRI tested Energy Management Circuit Breakers that could remotely cycle major loads to ease peak demand.
Electric vehicle (EV) charging, known for its high energy draw, is another area where smart breakers shine. Charging an EV can consume as much energy as running your entire home. Smart breakers balance this demand with other household loads, often eliminating the need for expensive electrical service upgrades.
"In the 'grid of the future,' managing the load is becoming just as important as managing energy at the source." - Eaton
Additionally, these breakers work seamlessly with renewable energy systems, ensuring smooth coordination with solar panels and battery storage.
Integration with Solar and Battery Systems
If you’ve added solar panels or battery storage to your home, smart breakers act as the command center, directing energy flow between the grid, your solar system, and your batteries. They track real-time solar production and prioritize using that self-generated energy for high-demand appliances during peak production hours - typically between 10:00 AM and 3:00 PM.
In the event of a grid outage, smart breakers extend the lifespan of your battery backup by cutting power to non-essential circuits and focusing on critical ones. Through the app, you can even adjust which circuits are considered "essential" on the fly, eliminating the need for costly secondary essential-load sub-panels.
The financial perks are substantial. By aligning energy-heavy tasks with times when solar production is high or utility rates are lower, smart breakers help you get the most out of your solar setup. In fact, homes equipped with these systems can cut energy usage by up to 30%. Additionally, dynamic load management prevents panel overloads, often making it possible to add solar, batteries, and EV chargers without upgrading your electrical service.
Safety Alerts and Fault Detection
Early Detection of Electrical Faults
Smart breakers take real-time monitoring to the next level. Using advanced sensors for current and temperature, they keep a constant watch on your electrical system, spotting potential issues before they escalate into fires or equipment failures. Unlike traditional breakers that simply react to faults after they occur, smart breakers can detect and respond to problems in microseconds.
These devices can identify common electrical issues like overloads, short circuits, arc faults, and ground faults - and they don’t stop there. They also send immediate alerts straight to your smartphone. For instance, if an appliance starts pulling 20A on a circuit rated for just 10A, the smart breaker not only detects the overload but also notifies you before tripping the circuit.
Temperature monitoring is another game-changer. By spotting rising heat caused by loose connections or failing components, such as motors, smart breakers allow you to intervene before the problem gets worse. This proactive approach doesn’t just prevent safety hazards - it also reduces the risk of costly outages and improves energy efficiency by ensuring smoother operation.
"The advancement of the smart circuit breaker helps contribute to your ability to address this challenge both in terms of monitoring asset health and to move you from a physical-based 'go check every breaker and review measurements' to a predictive asset health model." - ABB
By catching issues early, these systems not only improve safety but also help ensure that your equipment lasts longer.
Extending Equipment Lifespan
Smart breakers don’t just prevent hazards - they also shield your equipment from unnecessary wear and tear. By detecting overloads and minor faults early, they reduce the excessive heat and stress that can degrade insulation and damage components over time.
With their ability to monitor power usage and temperature spikes, smart breakers can pick up on early warning signs of equipment failure, allowing you to address problems before they snowball. This approach, known as condition-based maintenance, ensures that you only service equipment when it’s actually necessary - avoiding both arbitrary inspection schedules and catastrophic breakdowns.
"A predictive maintenance approach puts you in charge of when scheduling downtime for service, vs. being in a reactive mode, thus, further helping avoid costly unplanned outages." - ABB
Through the app, you can set custom power and temperature thresholds to catch anomalies early, giving you even more control over your system’s health and performance.

Smart Breakers vs. Traditional Breakers
Smart Circuit Breakers vs Traditional Circuit Breakers Comparison
Traditional circuit breakers are pretty straightforward - they stay inactive until there’s an overload or short circuit that trips them. On the other hand, smart breakers are like the next generation of circuit breakers. They actively monitor and manage individual circuits, offering a level of control and insight that traditional breakers just can’t match. To put it simply, Eaton compares the difference like this: "Comparing the EMCB [Energy Management Circuit Breaker] to a circuit breaker is like comparing a smartphone to a rotary-dial telephone". This ability to monitor and control circuits in real time opens up opportunities for better energy efficiency and smarter maintenance.
The main distinction is in visibility and control. Traditional breakers don’t provide any data on energy usage. In contrast, smart breakers offer revenue-grade metering with ±0.2% accuracy, allowing you to track energy consumption at the circuit level. This is especially useful because about 80% of a home’s electrical load typically comes from a few key circuits, like HVAC systems, water heaters, and major appliances. By focusing on these high-demand circuits, smart breakers make energy monitoring much more effective.
