Notes: Per UL486A/B Table 8 1) The current values for conductor sizes 1/0 - 4/0 AWG are based on the National Electrical Code (NEC), ANSI/NFPA 70, Table 310.16, 75°C column, multiplied by the number of conductors. The current for the 4 parallel conductors is additionally adjusted to 80% based on Table 310-15(C)(1). 2) The current values for conductor sizes 250 MCM and larger are in accordance with the NEC, NFPA 70, Sections 392.80(A)(2)(a) and 392.80 (A)(2)(b) for table 310.17, 75°C column, multiplied by the number of conductors and adjusted as follows: 250 - 500 MCM - adjusted to 65 percent 600 MCM and larger - adjusted to 75 percent NOTE: CONDUCTOR RANGES MARKED ON THE CONNECTORS ARE FOR NON-PARALLELING APPLICATIONS. ONLY THE CONDUCTOR RANGES NOTED ABOVE ARE APPROVED FOR PARALLELING APPLICATIONS.
