For instance, a 3 phase system and you are using one neutral and only 2 hot conductors then the neutral counts. Here's some examples of when to count the neutral as a CCC: 208Y/120 volt system-different circuit types: A)- 2 wire circuit w/ 1 ungrounded, 1 neutral = 2 CCC's. B)- 3 wire circuit w/ 2 ungrounded, 1 neutral = 3 CCC's.

Maximum Ampacity: 25 Amps. Note: These values are based on allowable ampacities of insulated conductors rated up to and including 2000 volts , not more than three current-carrying conductors in a raceway, cable, or Earth, single-insulated conductor in free air, and an ambient air temperature of 30°C (86°F).

NFPA 79 wire ampacity in raceway, specifically slotted panduit

I understand that is is not conduit. The derating chart 12.5.5 (b) says Raceway (and cable). Raceway is defined as many things including conduits, but also includes wireways. So if panduit brand wire duct is a wireway (i would think so), then it must also be a Raceway (by the definition in nfpa 79), thus it must be derated, maybe.

Each has a different ampacity for a specified gauge size, and these ampacities are found in NEC® Table 310.15(B)(16) for the calculations in this app. For example, 3/0 AWG copper has an ampacity of 200 amps at 75℃, while 3/0 AWG aluminum has an ampacity of 155 amps at 75℃. WIRE / CABLE TYPE:

installation. Multiply ampacity from Table 310.16 (P3) by this factor. Proceed to D5. P5: Determine ampacity adjustment factor based on total number of conductors in raceway, cable, or installed without maintaining spacing as specified in 310.15(C)(1). Multiply ampacity (P4 if "Yes" for D4; P3 if "No" for D4) by this factor. Proceed to D9.

Where the number of current-carrying conductors in a raceway or cable exceeds three, or where single conductors or multi conductor cables are stacked or bundled longer than 24 inches without maintaining spacing and are not installed in raceways, the allowable ampacity of each conductor shall be reduced as shown in the following table:
Raceway Fill Calculator - Cerrowire
https://www.cerrowire.com/products/resources/tables-calculators/raceway-fill-calculator/
Raceway Fill Calculator. The purpose of this calculator is to determine one of two values: the maximum number of conductors (wires) that can fit into a given type and size of raceway, or the minimum trade size of a raceway that is required for a given combination of conductors (wires). All calculations are based on the National Electrical Code®.
