No, this is not permitted.According to Article 310.15(B)(3) of the National Electrical Code (NEC), it is not permitted to run more than one circuit in a raceway where the circuit conductors are insulated by a material having a maximum rated operating temperature of 60°C (140°F) or less.Feeder conductors are typically insulated with materials such as PVC or THHN, which have a maximum rated operating temperature of 75°C (167°F) or 90°C (194°F). Therefore, it is not permitted to run two sets of feeder conductors in the same raceway. Flag for review
