The following is a typical conduit fill chart which shows data for different types of conduit such as EMT conduit IMC conduit and GRC conduit The possible wire gauges go from 14 AWG to 750 MCM and from conduit trade sizes of 1 2 inches to 4 inches What is the maximum number of 12 gauge wires permitted in 3 4 inch conduit A Master electrician Rex Cauldwell responds For practical purposes the maximum number of 12 gauge THHN conductors for a 3 4 inch EMT conduit is nine

The app will calculate the conduit fill percentages and jam probability for multiple conductors per NEC Guidelines Simply enter the conduit type and size then specify your conductors Table C 1 in Informative Annex C permits three 8 AWG conductors in trade size 1 2 electrical metallic tubing EMT An 8 AWG conductor has an outside diameter OD of 0 216 in from Table 5 and a 1 2 in EMT has an internal diameter ID of 0 622 in from Table 4
This table provides the initial recommended 40 fill capacity for Ethernet and coaxial cable based upon conduit trade size and cable jacket diameter Take note that conduit less than 3 4 3 4 trade size is not recommended for communications cable installation Because conduit sizes may vary by manufacturer please verify all dimensions prior to using this reference chart This guideline is based on National Electrical Code USA recommendations for conduit fill of runs with no more than two 90 bends
