Wiring Branch Circuit and Box Fill
About to embark on rewire of first floor of my house and much of second floor while I can EMT between floors (don't ask: chicago).
I'll be running 3/4 EMT in basement with stub ups to outlets. There are some locations where I could feed a good lenght of EMT through stud wall (near door openings) and I wanted to check that the porposed wiring plan was OK and if there are any special calculations of the proposed plan. Below is a link to the plan.
Is there any issue branching off to 3 receptacles and then branching off to another (or another run of 3)?
I want to check I'm interpreting the NEC box fill correctly. If I have 12/2 that passes through unbroken it counts as two. If another 12/2 comes in, is pigtailed to an outlet and then exits too (i.e. it branches like the two in the basement in above diagram), it counts as 6. All grounds count as 1. Do the cable clamps where the EMT enters the box count as 1 as well?
