we are geting ready to run power to 10-to-12 Exhaust fans (1/3 HP, 120 V) and G.C. does not want roof penetrations for couduit. Exhaust fans have a
3/4" chase to feed the motor through the the curb, but in some cases the ducts are bigger than the gravity dampers so G.C. wants us to run MC cable through the duct by penetrating it. I do not feel comfortable to run power in the duct and can not find anything in the NEC. would anybody know code section that does not allow this kind of installation. Thank you in advance for your help.
