Is there any information avalible in the NEC dealing with de-rating the current carrying capacity of wires (3 being run in this case) in a rigid steel conduit.

Thanks in advance.

Only three conductors in conduit do not require derating. For more than three conductors see Art.310.15B2. For ambient temperature corrections see Table 310.16 Correction factors.
