Was on a light commercial job and noticed that the 1/2" emt was a bit warm to the touch. The conduit contained lighting circuits that were appropriately load-- about 13 amps per phase. The conduit had 6 conductors 3 phases and individual neutrals. Each neutral is obviously a CCC but my question is would there be less heat in the conduit if it were wired as a MWBC? I realize the extra neutrals take up more space so heat will not dissipate as well but I want to know if there would actual be less heat produced with a MWBC?
