multi cable spacing

[odyssey1]

I have an application where there will be 6 #2 SE cables installed in a chase. I am trying to find the minimum spacing between cables. 310.15(B)(3)(a) lists the adjustment factors where multiconductor cables are installed without maintaining spacing for a continuous length longer than 24". what I am having trouble finding is what is the "spacing" that will not require a derating of the cable? Thanks for your help.

are you allowed to put SE cables in a chase?

The se cable is on the customer side of the service disconnect. It is for a multi family dwelling.

The code does not specify the amount of space that is required between the cables or raceways.

I'd have to say it is totally up to AHJ discretion, more details on this chase may be the deciding factor.

A "chase" could be anything with a hollow space in which the cables are installed - pull same cables in a pipe or tube and AHJ may claim you have bundled them, yet this chase could have similar cross sectional area to that pipe/tube and he may not say anything because it is constructed differently.
