The original edition of the tables of "Current Carrying Capacity of Impregnated Paper, Rubber, and Varnished Cambric Insulated Cables" was published in December 1943 by the Insulated Power Cable Engineers Association (IPCEA). These excellent tables were based on the best American practice at the time when they were published, and, as the title implied, were quite extensive in their scope. They served the industry well from the time of their publication to the present date.
