But even the most advanced circuit breakers currently on the market do not provide complete protection. Existing circuit breaker technology is inadequate against a phenomenon known as an arc fault. Eaton Corporation s Cutler-Hammer, a leader in circuit breaker research and development for more than 70 years, has addressed the problem of arc faults and today the company s proven technology exists to guard against this threat.
Arc faults can occur when insulation around cords, wires, or cables is damaged or deteriorated.
In many cases arc faults are the result of aging wiring. The simple act of nicking an electrical wire while installing dry wall, or running brittle extension cords under the carpet in heavily traveled areas can initiate an arc fault. The Challenge for Circuit Breaker Technology Circuit breakers prevent excessive or dangerous temperatures in conductors or conductor insulations and thereby reduce the risk of fires to some extent. The speed at which a conventional circuit breaker responds to a circuit overload is determined by duration and magnitude. Present-day technologies are adequate for the protection for circuit wiring, but are not capable of providing enhanced protection against arcing faults.
