Precision and Reliability in Breaker Testing

Faulty breakers pose serious risks and costly operational disruptions, and our technicians have found that approximately 1 in 10 plants are in this situation. At Interstates, we specialize in Primary Breaker Injection Testing services to address and mitigate these risks. Our skilled technicians meticulously evaluate your facility's low-voltage, molded-case, and metal-clad direct-acting AC circuit breakers up to 3000 amps by temporarily shutting down power, removing the breakers, and conducting comprehensive high-amp injection tests. This ensures each breaker trips within its specific time frames and set points, crucial for worker safety and compliance with NFPA 70B standards. Enhance the reliability of your operations and minimize the risk of unplanned downtime with our expert services.

The Importance of Breaker Injection Testing

Safety Assurance

Breaker injection testing verifies the operational integrity of circuit breakers, ensuring they trip under fault conditions. This is crucial for protecting human life and avoiding electric shock, fires, and other hazards caused by malfunctioning breakers.

System Protection

When breakers trip as intended, your electrical equipment and infrastructure are protected from damaging overcurrents or short circuits. Breaker injection testing helps avoid costly repairs, extends the lifespan of electrical components, and mitigates unplanned downtime.

Compliance and Standards

Regular breaker injection testing helps facilities comply with industry standards, safety regulations, and insurance requirements. Compliance with standards like NFPA 70B demonstrates a commitment to maintaining a safe and reliable electrical system.

Operational Reliability

When continuous electrical power is critical, breaker injection testing ensures that your electrical distribution systems are reliable, minimizing the risk of unexpected power outages that cause data loss, spoiled foods, or other operational damage.

Solutions to Optimize Your Operations

Regular Testing

Breaker injection testing is no longer a recommendation but a requirement under NFPA 70B as of January 2023. This regulation safeguards your facility against potential overcurrents that can lead to arc flashes, short circuits, and unplanned downtime. Understanding the impact on our clients, Interstates helps ensure compliance while significantly enhancing workplace safety, giving you peace of mind. The frequency of testing is determined by the criticality of each breaker, ensuring the most crucial components are inspected regularly to maintain optimal safety and reliability. Regular testing based on breaker criticality helps prevent unexpected failures and keeps your operations running smoothly.
