The purpose of this paper is to examine the application of low-voltage circuit breakers to control the energy released during an arc-flash occurrence. It contrasts arc-flash incident-energy values obtained by calculation with values obtained by direct testing. It examines values at low fault current levels where long duration events may be expected. It also(More)
Arc Fault Circuit Interrupters (AFCIs) are required by the National Electrical Code to further reduce the hazards resulting from residential electrical fires. The UL 1699 Standard contains the testing and certification requirements for various types of AFCIs. Both the NEC and UL 1699 Standard are American National Standards Institute documents, established(More)
Many people do not understand that their hearing is a valuable, yet delicate, sense which they damage with regularity. While the sense of sight is typically recognized as delicate, and given appropriate protection considerations, the sense of hearing is not as readily apparent. This paper will explain some of the physiological aspects which give us our(More)

Many people do not understand that their hearing is a valuable yet delicate sense that they damage with regularity. They also do not realize that noise-induced hearing loss cannot be fixed with a hearing aid. Although the sense of sight is typically recognized as delicate and given appropriate protection considerations, the sense of hearing is not treated(More)
A common practice is to install a service disconnect or a main disconnect for a feeder system in the same enclosure compartment as the downstream overcurrent protective devices. This can result in potential safety risks of shock and arc flash. This paper will address the advantages and disadvantages of isolating a service disconnect for electrical service(More)
