Cheers, thanks for the comment. Education is a challenging task in every sector-the electrical trades included. Perhaps, in time, educators will reach beyond the basics of their texts and creatively connect concepts to the field.

How many strap should be count for a 14-30R receptacle? Thank you.

[@Red_Seal_Electricin]

Hi dragon818, in reference to box fill, any receptacle is considered to be mijnted one single strap. This would include single receptacles, duplex, and other quirky combos such as a switch with light or switch with receptacle. Let me know if I understood your question correctly.

@ Hi there, the 14-30R usually uses for a dryer, it is larger than a single strap. Does that count 2 straps?

Another question. Do you count the 16awg wire for 0-10v dimmer?

[@Red_Seal_Electricin]

Great question, typically no. The volume of wire contained in a box by these conductors is so small that it is not considered significant enough to count. This is evident with table 22 & 23 having volume data down to #14awg, no smaller.

When you gang 2x 3104, do you multiply the capacity by 2 or you have to subtract the volume of the 2 side that you remove?

[@Red_Seal_Electricin]

Good question. Volume of the two boxes added together, typically twice the volume for a gangable box.. no need to subtract sides.
