WebCircuit Breaker Testing is essential to ensure the safe and reliable performance of this key link in the power asset chain. Circuit breakers perform three main tasks: They should conduct the current as efficiently as achievable, when closed. When open, they must insulate the contacts from one another as effectively as possible.

WebMay 25, 2016 · Infrared scanning is used to inspect electrical equipment because excess heat is usually the first sign of trouble. Loose connections, imbalanced and/or overloaded circuits, defective breakers, damaged switches, faulty fuses, and material defects all lead to equipment failure and these are detectable by an infrared inspection.
Continuous Amps (Ir) varies the level of current the circuit breaker will carry without tripping. Ir is a percentage of the circuit breaker’s nominal rating (In). Continuous amps can be adjusted from 20 to 100 percentof the circuit breaker’s nominal rating.
