Rationale

Revising Table 1, to add 250 kcmil Cable Size and 350 kcmil Cable Size, as in Table X1.1. 250 and 350 kcmil Cable Sizes were added to the standard at the last revision (missed Table 1). Also adding a note to Figure 3, on how to measure the Clamp - Cable - Cluster - Cable - Clamp length for Cable Resistance calculations. Currently we give a diagram, but do no provide instructions for measuring the setup.
