Box capacity question:
One, single pole light switch in plastic box with a capacity: 14 0 cubic inches, accepts up to 7/14.
All wire will be 14/2:
One power source in.
One through power wire for further outlets or switched lights.
One power out to two, paired on same switch, small halogen ceiling spot lights.
Thus far in projects, I've been able to use boxes definitely over capacity to avoid making a definite calculation on capacity. But I don't want to estimate on this one, it may be too close. (I've read numerous, but have never been able to find a clear cut explanation on how to calculate capacity.)
Is there enough capacity in this case?
