I would appreciate anyone who have an experience regarding wattstopper's room controller chiming in.
The device in question is Legrand Wattstopper's LMRC-210 series room controllers.
Referencing the online product sheet, the controller can be mounted directly to a 4" junction box, acting also as a cover.
My question is that do the wires coming out of the LMRC room controller contribute to the calculation of the conductor fill per NEC standards?
NEC 314.16 (B)(1) Exception states that "An equipment grounding conductor or conductors or not over four fixture wires smaller than 14 AWG, or both, shall be permitted to be omitted from the calculations where they enter a box from a domed luminaire or similar canopy and terminate within that box."
What I understand from this statement is that pigtails from the mounted devices that do not leave the box can be omitted from the calculations, and the wires coming out from the backside of the LMRC can be interpreted as such thus not being counted.
