Allowable Ampacities of Conductors

allowable ampacities insulated conductors

This table indicates the allowable ampacities of insulated conductors in a raceway. It is important to use raceways safely, so that the wires housed together do not overheat. This chart will enable you to calculate how many wires, and of what ampacity, can be paired together in a raceway for safe use. This chart takes into account the temperature rating of the conductor, and material.
