Multiconductor cable inside raceway derating

[jsim]

Greetings,

Considering the following scenario: some multiconductor cables inside a raceway, for example, a PVC Conduit
(Please check the attached image)

Each multiconductor cable has three current carrying conductors, for example each supplying a different three phase load.

What should be the Adjustment Factor for More Than Three Current-Carrying Conductors considered for the ampacity of this section?
- 100% (No derating), as each cable has no more than 3 CCCs or,
- 50%, given 3CCCs per cable times 4 cables = 12CCCs inside the raceway

Thanks in advance!

The latter.

100% (No derating), as each cable has no more than 3 CCCs or,

If they were in separate raceways this would apply.

50%, given 3CCCs per cable times 4 cables = 12CCCs inside the raceway

Yes this 12 CCC's would apply.
