To increase the reliability of modules,and thus of systems assembled from them, they are frequentlyconstructed using parallel load-sharing components. Examples includejet engines, electrical power networks, and telecommunicationsnetworks. We consider the situation when the components operateindependently, but when any one of them fails, the load of thefailed component is instantaneously distributed among the workingcomponents. The entire module fails when the last working componentfails. We analyze the survival probability and residual lifeexpectancy of such modules. An obvious application is to the case ofthe 1998 Auckland power supply failure in New Zealand.
