In this comprehensive guide, we will discuss why electric lawn mower tripp the breaker with common causes, and practical solutions to fix it and lastly, we’ll offer practical tips and preventive measures to ensure a smooth and uninterrupted mowing experience. 

Why Electric Lawn Mower Tripps the Breaker

To understand exactly why your electric lawn mower is tripping the breaker, it’s essential to have a basic knowledge of electrical circuits and the role of circuit breakers in lawn mower. Circuit breakers are safety devices that automatically cut off the flow of electricity when an overcurrent condition arises, protecting electrical components and avoiding potential risks like fires or electrical shocks.

When an electrical circuit becomes overloaded or experiences a short circuit, the breaker trips to cut off the power supply, preventing further damage to the system. This safety mechanism is crucial, as it helps prevent electrical fires or damage to expensive appliances and equipment.

05 Common Causes Why Electric Lawn Mower Tripp the Breaker

Now that you understand the purpose of circuit breakers, let’s explore the most common causes of breaker tripping with electric lawn mowers.

Overloaded Circuit

One of the primary reasons for a breaker tripping is an overloaded circuit. As you know, electrical circuits are designed to handle a specific amount of electrical load. When you try to draw more current than the circuit can handle, the breaker trips to prevent potential damage to the wiring or appliances.

In the case of electric lawn mowers, this issue can arise when the mower is plugged into a circuit that is already heavily loaded with other appliances or devices. The combined electrical draw from all the connected devices may exceed the circuit’s amperage rating, causing the breaker to trip as a safety measure.

For instance, if you have your electric lawn mower running on the same circuit as a refrigerator, air conditioner, and a few other high-power appliances, the total electrical load may be too much for that circuit to handle. As a result, the breaker trips to prevent overheating, potential fires, or damage to the electrical components.

Solutions:

The most straightforward solution is to identify the devices or appliances connected to the same circuit as your electric lawn mower and distribute them across different circuits. This will reduce the overall load on any single circuit, preventing the breaker from tripping due to overload.

Upgrade to a higher amperage circuit breaker: If redistributing electrical loads is not feasible or practical, you may consider upgrading to a higher amperage circuit breaker.

For optimal performance and ultimate peace of mind to avoid breaker trips, consider installing a dedicated circuit specifically for your electric lawn mower. This way, you won’t have to worry about other appliances causing an overload on the same circuit.

Faulty or Damaged Power Cord

The power cord is the lifeline that connects your electric lawn mower to the electrical outlet, and any damage or defect in this cord can lead to electrical issues, including breaker trips.

Over time, power cords can become frayed, cracked, or damaged due to exposure to various environmental conditions or improper handling. These damages can cause short circuits or ground faults, triggering the circuit breaker to trip as a safety measure.

For example, if the power cord’s insulation is damaged, exposing the internal wires, it can create a potential short circuit or electrical hazard. Similarly, if the cord is kinked or bent severely, it can compromise the flow of electricity, causing the breaker to trip.

Solutions:

Before you use it again, carefully inspect the entire length of the power cord for any visible signs of damage, such as cuts, cracks, or exposed wires. Replace the cord immediately if you notice any damage.

If the power cord is damaged beyond repair, replace it with a new, heavy-duty outdoor extension cord designed specifically for lawn mower use. Ensure the cord meets the required gauge and length specifications for your electric lawn mower.

Remember using a lightweight extension cord can increase the risk of breaker tripping due to inadequate power delivery.

Motor Issues

The motor is the heart of your mower, as it is responsible for powering the blades and propelling the machine forward. However, motor problems can cause excessive current draw, leading to breaker trips.

Blade obstructions, worn brushes, or failing bearings are some main factors which contribute to motor issues. When the motor encounters resistance or mechanical issues.

If a stick or a rock gets caught in the mower’s blades, it can create significant resistance and strain on the motor. This increased workload causes the motor to draw more current and potentially leading to sputtering issues

Similarly, worn brushes or bearings can cause the motor to work harder, leading to increased current draw and potential breaker trips.

Solutions:

You can extend the motor’s lifespan and prevent excessive wear and tear by cleaning and lubricating the motor.

Inspect the motor housing for any signs of damage, such as cracks or leaks. Look for any debris or obstructions that may be interfering with the motor’s operation.

Don’t spend too much time in cleaning If the motor is significantly damaged or worn out, it should be necessary to replace it.

Circuit Breaker Problems

While circuit breakers are designed to protect electrical systems, they can also experience issues that lead to frequent tripping. Electrical components like capacitors, switches,wiring and Alternator can fail or become faulty over time, causing the breaker to trip unexpectedly.

Burning smells, sparks that may be seen, or discoloration surrounding the breaker panel or electrical components are all common indicators that an electrical component is failing. These problems may result in overload situations or short circuits

Solutions:

Give close attention to any indications of damage, such as charring, melting, or corrosion, on the circuit breaker panel, wiring, and electrical components.

If you have the necessary skills and knowledge, you can use a multimeter to test electrical components for proper functionality. However, if you’re unsure or uncomfortable with this process, it’s best to seek professional assistance.

Lastly make sure to change any problematic electrical components: It is important to swap out any malfunctioning parts for brand-new, compatible ones.
