(H) Under-Chassis Wiring (Exposed to Weather).
Where outdoor or under-chassis line-voltage (120 volts nominal, or higher) wiring is exposed to moisture or physical damage, it shall be protected by a conduit or raceway approved listed for use in wet locations or where subject to physical damage. The conductors shall be listed for use in wet locations. Where wiring is exposed to physical damage, it shall be protected by a raceway approved for use where subjected to physical damage.
Substantiation
A conduit is a raceway, "conduit or" is redundant.
Requiring raceways to be listed for wet location is reasonable.
Having the phrase following the first or be referred to by the phrase following the second or is very confusing.
Listed for wet location is used in 300.50(B), 310.10(C)(3), 314.15, 330.10(A)(11)c., 366.6(A)(2), 366.120(2), 396.10(B)(2), Table 400.4 Note 9, 410.96, 547.5(C)(2), 547.8(C), 550.15(H), 725.179(E), and 760.179.
