Abstract Description of a method for testing samples of cable by simulating an arcing fault in a test chamber. The insulation of a cable should not catch fire in the time it takes for a circuit breaker to detect the fault and de-energise the cable. A nomogram is given for determining if a cable of a particular length and diameter will be safe at various fault currents.
