What is the maximum number of conductors in one conduit?
Allowable Conduit Fill Capacities
| Size and Type of Conduit | 14 AWG Wire | 12 AWG Wire |
|---|---|---|
| 1/2-inch EMT | 12 | 9 |
| 3/4-inch EMT | 22 | 16 |

Is electrical conduit measured inside or outside?
Pipe is usually measured by NOMINAL PIPE SIZE (NPS). Although it is related to the outside diameter, it is significantly different. For example, a 1-1/2″ pipe size actually has an outside diameter of 1.9″ NOT 1.5″. The table below cross-references the nominal dimension of a PIPE with its actual outside diameter.
