Scope and Assumptions Fault codes are indicators of general types of failures. A fault code may not be as specific as other QoS metrics. A fault code may simply indicate the general area of a fault to aid monitoring or troubleshooting of areas that could otherwise be...

02748a-000000-000000 1 Scope 1.1 These requirements cover fast operating devices intended to interrupt currents associated with arcing faults, having interrupting times faster than conventional overcurrent devices. 1.2 These requirements cover open type devices that are intended to be...

027480-000000-000000 1 Scope 1.1 These requirements cover equipment intended to quench arcing faults by creating a lower impedance current path, located within a controlled compartment, to cause the arcing fault to transfer to the new current path. 1.2 These requirements cover...

This document provides guidance in performing Failure/Fault Analyses in relatively low complexity systems. Methodologies and processes are presented and described for accomplishing Failure/Fault Analyses. ARP4761 provides updated methods and processes for use on civil...
