The detection of a short in or on an electronic card or plane can be made difficult because of a variability of real load current to the card or plane. If the load current is at its minimum, and if the addition of the fault current does not add up to the maximum allowable load current, then no unacceptable condition can be detected in the load circuit. Therefore, a fault can persist until combustion occurs and is further propagated by electrical energy. However, the combustion will produce a char between all voltage and/or ground planes of the card or board.
