Many factors influence the amount of current a given cable can transfer. For example, insulation, temperature, and the number of bundled wires. These tables help you determine the cable's ampacity, or simply, the ability of the cable, in varying conditions, to carry amps (current) before it fails or overheats. Why flip through over 3,000 pages when you don't have to. Searchable PDF and convenient software help you perform your cable ampacity work with ease.

Working Group Details
Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
