I have been told that the ***plug wires*** for a 120V wired smoke
detector do not count towards the wire fill of the box. I just wanted
to confirm that this is correct or incorrect.
"Where ... not over four fixture wires smaller than No. 14... enter a box from
a fixture canopy and terminate within that box, it shall be permitted to omit
these conductors from the calculations." [NEC, Art. 370-16 (a) 1 exception]
