where in the nec code does it give the volume for plaster rings. i'm working on an example problem and it says that a 4 x 2 1/8 box has a plaster ring of 3.6 cu. inches.
i have been looking in section 314 with no luck.
where can i find the volume of plaster rings / how do i calculate the volume?
as always thank you in advance.
