Short-Time Current Ratings for Aircraft Wire and Cable

This paper gives the results of a series of tests on two sizes (AN-16 and AN-8) of insulated aircraft wires and cables, which were made to determine their permissible short-time current-carrying capacities. The times under consideration ranged from 0.01 to 1,000 seconds. A description is given of a very simple but adequate electrical test together with an accompanying insulation test to determine what are considered permissible transient temperatures. Tentative recommendations of short-time current-carrying capacity for aircraft cable sizes AN-22 to AN-00 are made.
