Short description
This standard contains guidelines for calculating amperages and selecting wires for temperatures from 200 °C to 450 °C and for voltage ratings up to and including 1000 volts rms. Ampacity charts, temperature correction factors, and derating factors are provided along with extensive examples of calculations. This information is provided to assist the user in their selection of a wire or cable for a particular application. This guideline contains the best engineering estimates for calculation, but it cannot guarantee a successful performance. It is recommended that a trial installation be prepared and appropriate evaluations be conducted to assure acceptable performance of the completed systems.
