i have a job that requires i run some panduit down a wall it will have 26 conductors between # 12 and #10 wire i need to know the percentage of fill im allowed and the derating factors that apply

Are you talking about PVC wire duct? Why would you want to do such a thing? Is this in an electrical rooom where its well protected from people fiddling with it? Just the idea of this makes me nervous.
 
Re: auxxillary gutters

The term panduit, to me means the slotted plastic duct with a removable cover. I do not think this is an acceptable raceway for single conductors like THHN, MTW, etc. when attached to a wall. It is normally only used inside of a control panel for grouping wires.

An auxilliary gutter is normally a totally enclosed metal raceway with a lid (2X2, 4X4, etc.)

There is a section in the NEC that addresses auxilliary gutters.

The term "panduit" to me, is the same thing wireman describes. It is not intended for the application you describe, unless , by chance, this is a "communications closet" & all of these conductors are low voltage Class 2.

Do not use exposed panduit for enclosing conductors of power & lighting circuits.

#10 and #12 would be really unusual comm wires. :)
