Table 52, 53, 54, 55
Short-circuit K values and temperature limits
The fault rating tool reads the k factor for the conductor start temperature and the short-circuit temperature limit. The limit comes from the insulation class and the conductor size band, or from the joint in the run when the joint is the lower of the two.
