allowable ampacities of conductors

ugly-book-banner spacer

Thank you for seeking out our resources to complete your electrical project! This table indicates the allowable ampacities of insulated conductors in a raceway.

A raceway is a channel that can mount on a surface such as a desk, for cables to run through, keeping wire clutter to a minimum. 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.

Our range of raceways and accessories include metallic raceways, non-metallic raceways, raceway clips and couplings, raceway covers, raceways elbows, raceway end fittings, raceway outlet box covers and plates, and raceway outlet boxes.
