This is for a specific application only. 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.

I am considering a modification to the values in table 310.15( c )( 1 ), adjustment factors for more than 3 current carrying conductors. 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),. C) multiply the ampacity by the derating.

Nec Derating Chart - This is for a specific application only. Hello, i understand how to use the table to derate multiple wires in a single raceway. 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),. If i understand it, you are allowed to derate up to 83 % the feeder or service conductors supplying. I had a specific situation that.
