NOTES:
(1) The ampacity of a given conductor type at these higher ambient
temperatures is obtained by multiplying the appropriate value from Table
1,2,3, or 4 by the correction factor for that higher temperature.
(2) These ampacities are only applicable under special circumstances where the
use of insulated conductors having this temperature rating are acceptable.
