Does anyone know where I can find in the NEC the definition of current carrying conductors? I have a system that will be in use for 44-48 minutes in one 24 hour duration. Is this clasified as a current carrying conductor?

The NEC has some clarifications about when a conductor has to be counted as a current-carrying conductor, in the context of derating. See 310.15.(B)(2)(a). But it does not define the phrase as an entitiy in itself. It also does not put a time constraint on the concept. For the 44-48 minutes you describe, the conductors do count as current-carrying conductors.

Charlie,
First of all Thank you for the welcome to the Forum. Great site learning how to navigate it. Thank you for your reply and yes I have visited those articles looking for a definition. Have another question, where can I find a chart to figure out how many conductors I can put into a 6X6X60 i seen the chart on Trade Boxes etc, nothing for Wireways or Raceway there 314.16 (A).

Look at 310.15(B)(4) for when the neutral counts as a CCC.
Wireways are in Articles 376 and 378.
