However, certain industrial appliances can easily trip circuit breakers, causing downtime, production delays, and even safety hazards. In this article, we will discuss which industrial machines are likely to trip circuit breakers and provide tips on preventing circuit overloads.
What Trips Your Circuit Breaker
Circuit breakers are designed to trip in two instances: when there is an overload or a short circuit in your electrical system. It’s important to determine the root cause of the issue before repeatedly resetting the breaker. Below are some of the appliances that could cause your circuit breaker to trip.
1. Heavy Machinery
Heavy machinery such as cranes, lifts, and large motors can significantly strain an industrial electrical system, especially during startup or shutdown. The starting surge of these machines can cause a temporary overload, which can trip the circuit breaker.
To prevent heavy machinery from tripping the circuit breaker, it is essential to have a comprehensive electrical system design that considers each machine’s power requirements. This design should consider the total connected loads and ensure the circuit breakers are sized correctly. Additionally, installing soft starters or variable frequency drives can help reduce the starting surge and prevent overloads.
2. Welding Equipment
Welding equipment is another common industrial appliance that can easily trip circuit breakers. Welders require a large amount of power to create the arc needed for welding, which can cause a temporary overload and trip the circuit breaker.
To prevent welding equipment from tripping the circuit breaker, it is important to use the correct circuit breaker size for the machine and ensure that the electrical system is designed to handle the power requirements of the welder. This includes ensuring that the wiring and cabling are properly sized and that the circuit breakers are rated for the specific equipment being used. Additionally, using a lower voltage setting on the welder can help reduce the power demand and prevent overloads.
3. High-Intensity Lighting
High-intensity lightings, such as metal halide or high-pressure sodium lamps, can also put a strain on an industrial electrical system, especially during startup. These lamps require a significant amount of power to start up and can cause a temporary overload, which can trip the circuit breaker.
To prevent high-intensity lighting from tripping the circuit breaker, it is important to use a separate circuit for the lights and ensure that the electrical system is designed to handle the power requirements of the lamps. This includes properly sizing the circuit breakers and ensuring that the wiring and cabling are rated for the specific lighting being used. Additionally, using LED or fluorescent lighting can help reduce the power demand and prevent overloads.
4. Compressors
Compressors are essential for many industrial operations, but they can also cause circuit breakers to trip if not properly managed. Compressors can cause a temporary overload when starting up or running at high capacity.
To prevent compressors from tripping the circuit breaker, it is essential to properly size the circuit breakers and ensure that the electrical system is designed to handle the power requirements of the compressor. This includes considering the starting surge of the compressor when selecting the circuit breaker size and ensuring that the wiring and cabling are rated for the specific compressor being used. Additionally, using a soft starter or variable frequency drive can help reduce the starting surge and prevent overloads.
5. Electric Motors
Electric motors are used in a wide range of industrial applications, from conveyor systems to pumps and fans. However, these motors can easily trip circuit breakers, especially when starting up or running at high capacity.
To prevent electric motors from tripping the circuit breaker, it is important to select the correct circuit breaker size and ensure that the electrical system is designed to handle the power requirements of the motor. This includes considering the starting current and running current of the motor when selecting the circuit breaker size and ensuring that the wiring and cabling are rated for the specific motor being used.
In addition to selecting the correct circuit breaker size, using soft starters or variable frequency drives can help reduce the starting surge of the motor and prevent overload. These devices can also improve the efficiency of the motor and extend its lifespan.

Preventing Circuit Overloads
Preventing circuit overloads is essential for ensuring the safety and productivity of an industrial facility. In addition to properly sizing circuit breakers and selecting the right appliances for the electrical system, there are several other steps that can be taken to prevent overloads:
1. Conduct Regular Maintenance
Regular maintenance of electrical equipment can help identify potential issues before they become a problem. This includes inspecting the wiring and cabling for signs of wear and tear, checking circuit breakers for proper operation, and testing appliances for electrical safety.
2. Use Power Monitoring Systems
Power monitoring systems can help identify potential overloads before they occur. These systems track energy usage and can provide alerts when power usage approaches or exceeds the capacity of the electrical system.
3. Implement Load Shedding
Load shedding reduces or sheds non-critical loads when the electrical system approaches capacity. This can help prevent overloads and ensure that critical equipment remains operational.
Conclusion:
In conclusion, industrial appliances can easily trip circuit breakers, including heavy machinery, welding equipment, high-intensity lighting, compressors, and electric motors. To prevent overloads and ensure the safety and productivity of an industrial facility, it is essential to properly size circuit breakers, select the right appliances for the electrical system, conduct regular maintenance, use power monitoring systems, and implement load shedding. By following these tips, industrial facilities can avoid downtime, production delays, and safety hazards caused by circuit overloads.
FAQs
Q: How can I prevent my circuit breaker from tripping when using high-power appliances?
A: To prevent your circuit breaker from tripping, you should avoid using multiple high-power appliances on the same circuit simultaneously. You can also reduce the load on the circuit by unplugging other appliances or turning off lights when using high-power appliances.
Q: What should I do if my circuit breaker keeps tripping when using an appliance?
A: If your circuit breaker keeps tripping, unplug the appliance and try plugging it into a different circuit to see if the problem persists. If the machine continues to trip the circuit breaker, it may be faulty and should be inspected by a qualified electrician.
Q: Can a circuit breaker trip even if there is no fault or overload?
A: Yes, circuit breakers can also trip due to old age or wear and tear. Over time, the contacts inside the breaker can become worn, reducing their ability to conduct electricity efficiently. This can cause the breaker to trip even when there is no apparent fault or overload.
