Box Volume Calculation

newenergy

To calculate the volume of a junction box needed in 314.16 you get to table 314.16(B) which only goes to 6 AWG.

I don't see anything about volume requirements for bigger conductors.

If you keep going you get to 314.28 which tells you the minimum dimension of the jbox from any raceway entry to the opposite wall, but no volume requirement. Is there just no specific volume requirement as long as you meet the requirement for that dimension?

Once you reach #4, the Code isn't interested in volume (in³), but bending space
