Please save me (and him) the research...what would be the minimum

be nutted together in given box?

Box fill summary: minimum required box volume is a sum of terms, each
of which depends on the wire size, in particular 2.00 in^3 for a #14
wire and 2.25 in^3 for a #12 wire. You individually count all current
carrying conductors entering the box (hot and neutral), you count all
the EGCs as only one wire, you count any internal wire clamps, and you
count each device (yoke) in the box as two allowances.

I need some clarification...

count all current carrying conductors entering the box (hot and
neutral), you count all the EGCs as only one wire

So, is a piece of 14/2 with ground counted as 3 "terms" or 2? i.e.
requireing 6 in^3 or 4 in^3?

you count any internal wire clamps

Is an internal wire clamp the same as a wire nut or do you mean the
clamp that secures the romex in the hole? What is the X in^3 for
either item? If it's the wire nut, wouldn't it depend on the size of
the wire nut which is dependent on the number of conductors it
secures?

count each device (yoke) in the box as two allowances

What's a yoke? In the case of this "light fixture ceiling box" how
does it (device/yoke) enter into the equation? It's not *in* the box,
per se.

Thanks
