jdevlin...this is one practice that i never liked.i under stand that your running less wire(cost)but if you lose the neutral you could have 240 volts going to a receptacle.
i know they do sell this cable.standard mc cable with a super neutral.but i think it/'s 3#12 and a#10 neutral and a #12 ground for a 3 phase panel .don't no if it comes in #14/w 10 neutral.
i don't see a violation here.15 amp ocp and a #10 neutral.better then the 14/3 used and someone changes the breakers around.
