    NEC 610.14(A) Ampacity for Crane Feeders

    How would i figure out the equivalent short-time aluminum ampacities for crane feeders. Table 610.14(A) only lists ampacities for copper. Or does this imply that I cannot use aluminum for feeders to cranes?

Where the conductor material is not specified, the material and the sizes given in this Code shall apply to copper conductors. Where other materials are used, the size shall be changed accordingly.
