Dimensions and weights are nominal; subject to industry tolerances.
(1) Ampacities are in accordance with Table 310.60(C)(73) of the NEC for triplexed or three single conductor copper cable in isolated conduit in air, based on a conductor
temperature of 105ºC (221ºF) and an ambient air temperature of 40ºC (104ºF).
(2) Ampacities are in accordance with Table 310.60(C)(77) of the NEC for triplexed or three single conductor copper cable in underground ducts (three conductors per duct),
based on a conductor temperature of 105ºC (221ºF) and an ambient earth temperature of 20ºC (68ºF), electrical duct arrangement per Figure 310.60 Detail 1, 100% load
factor, and earth thermal resistance (rho) of 90.
(3) Ampacities are based on single conductor Type MV-105 sizes #1/0 AWG and larger in an uncovered tray in accordance with Section 392.80(B)(2) of the NEC at an
ambient air temperature of 40ºC (104ºF): the ampacities are based on 75% of the values per Table 310.60(C)(69). For cable trays with unventilated covers for more than 6
feet, the ampacities shall not exceed 70% of the values shown above.
(4) Based on nominal cable diameters, three single cables in the duct (PVC Schedule 40) with no ground wire and a maximum of 40% fll. Jam ratio has been considered,
but it should be checked for individual installations.
