Nec Derating Chart

Nec Derating Chart - Getting back to conductors and ambient temperature, the purpose of derating for temperature is that if the ambient is high but you reduce the ampacity (i.e., lower i2r heating),. Can anyone tell me if it is true that more than single dlo cable in a conduit starts the derating process per 2011 nec 310.15(b)(3)(a)? B) find the derating factor from table [310.15 (b) (2) (a)] based on the number of current carrying conductors in the raceway. I am considering a modification to the values in table 310.15( c )( 1 ), adjustment factors for more than 3 current carrying conductors. What i am not sure of is how to do this for branch circuits where the load is variable. If i understand it, you are allowed to derate up to 83 % the feeder or service conductors supplying.
