Safety and Compliance Through Breaker Injection Testing

September 23, 2024

In the highly regulated world of industrial operations, ensuring the reliability and safety of your electrical systems is crucial. One essential service that helps maintain these standards is breaker injection testing, which has become increasingly important following updates to the NFPA 70B standards in 2023. Interstates’ breaker injection testing service is designed to address this need, offering comprehensive evaluations to ensure the operational integrity of circuit breakers and ensuring you comply with industry standards.

What is Breaker Injection Testing?

Breaker injection testing involves passing a controlled amount of current through circuit breakers to ensure they trip at the correct amperage and within the designated time frames. According to Adam Dittbenner, Instrumentation Manager at Interstates, “Breaker injection testing passes amps through breakers to ensure they trip at the proper number of amps and at the proper time. It is important because it proves that the breaker is properly protecting the equipment downstream of it.”

This testing is essential for verifying that breakers will function correctly in fault conditions, thus safeguarding electrical systems and preventing costly disruptions or unsafe conditions.

NFPA 70B and Its Impact

With the 2023 updates to NFPA 70B, breaker injection testing has transitioned from a best practice to a standard requirement. “This means that periodic testing must be performed on breakers to make sure they trip at the proper set point,” explains Dittbenner.

Compliance with NFPA 70B not only ensures your adherence to safety regulations but also demonstrates a commitment to maintaining a safe and reliable electrical system. Regular testing helps avoid potential hazards at your plant such as electric shocks, fires, and equipment damage caused by malfunctioning breakers.

The Testing Process

Interstates’ process for breaker injection testing is thorough and precise. It involves powering down the plant’s electrical system, removing the breakers, and connecting them to specialized testing equipment to check their trip set points. This ensures that each breaker operates correctly under fault conditions. Dittbenner says, “Primary breaker injection testing involves powering down the plant’s electrical system, removal of the breaker, and connecting it to our tester to check its trip set points.”

Our technicians are skilled in conducting these tests and can coordinate breaker testing with other maintenance activities to minimize downtime and maximize efficiency. This holistic approach ensures that all aspects of electrical safety and reliability are addressed.

Enhancing Facility Operations

The benefits of breaker injection testing extend beyond compliance. Regular testing and maintenance of circuit breakers contribute significantly to the overall reliability and efficiency of your facility’s operations. Properly functioning breakers protect electrical equipment from overcurrents and short circuits, reducing the risk of unplanned downtime and expensive repairs.

Interstates’ breaker injection testing service can be tailored to include additional actions such as infrared scanning for hot spots, cleaning, exercising, contact resistance testing, and insulation testing. These tasks, performed in conjunction with breaker injection testing, provide a comprehensive assessment of your electrical system’s health and help detect potential issues before they escalate.

Proactive Support

Understanding the criticality of each breaker and the facility’s specific needs is key to effective breaker injection testing. Interstates offers a detailed review of your facility to determine the necessary actions outlined in the NFPA 70B standard. This proactive approach helps identify and address electrical deficiencies, ensuring long-term reliability and safety.

If you’re ready to confirm the compliance and safety of your electrical systems, a great first step is partnering with a company like Interstates that has vast experience with this essential service. Our expertise and comprehensive approach ensure that your electrical systems remain safe, reliable, and efficient, protecting both your operations and your workforce.
