Failure to periodically test a circuit breaker can have major safety, operational and financial ramifications. ![image](https://cdn.forumautomation.com/original/2X/d/dac33024b0f305402f4db19b6084a4dc48bae925.jpeg) The primary drawbacks include: Defective breakers that fail to trip during fault or overload conditions can lead to excessive heating of conductors & components increasing the danger of electrical fires. ## Damage to Electrical Equipment Malfunctioning breakers can cause electrical equipment to fail prematurely or permanently. ## Risk of Personal Injury Faulty breakers pose a risk of personal injury by failing to isolate electricity under fault conditions leading to electric shock & arc-flash risks. ## Unplanned Power Outages Unpredictable or improperly reset breakers can cause unplanned power outages disrupting businesses and reducing productivity. ## Higher Maintenance and Repair Costs Undetected breaker problems can lead to costly repairs, equipment replacement & prolonged downtime. Regular circuit breaker testing is required to maintain electrical safety, system reliability and the safety of both equipment and personnel. ## International Standards for Circuit Breaker Testing 1. **IEC 62271-100:** High-voltage AC circuit breakers. 2. **IEC 62271-110:** High voltage DC circuit breakers 3. **IEC 60947-2:** Low-voltage circuit breakers.
