Greetings,

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.

Thanks,
William

When did they start putting spark plugs in smoke detectors?

Pigtails usually aren't counted towards box fill. Never know with some
inspectors, 'tho.

Matt,

120V smoke detectors normally have a male plug. The female plug has 3
leads which extend into the octagon box and are attached with wire
nuts.

Hope this helps,
William

Per the NEC, pigtails are *never* counted: "Conductors, no part of which
leaves the box, _shall_not_ be counted." [emphasis added]

That's correct.

"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]
