Re: 2/0 in emt
This type of question generally depends on the type of conductor. For THHN, as an example, you need 2 inch. For RHH, a 2 inch will hold 4 conductors of size 2/0, but in order to figure out whether a ground would also fit you need to calculate the actual areas of the conductors. But you can find this information in Annex C of the NEC.

Re: 2/0 in emt
Can someone shed some light on how to determine whether you use Table 8, conductor properties, or Annex C, conductor insulation for fill calculations.
