"Trade size" is a measure of the diameter of the component wire. Also used in light duty chain. Specifically you can read "trade size" as "Wire Guage" 18 = 18, 16 = 16 etc. TRADE SIZE METRIC SIZE DESIGNATIONS 1/2 16 3/4 21 127 1 1/4 35 1 1/2 41 253 2 1/2 63 378 3 1/2 91 4 103 5 129 6 155 Letter designators will be addressed by each product group in the standards revision process (whether it be NEMA, UL, CSA, harmonized, binational or trinational standards). The largest size raceway for the left/right (horizontal) dimension is a 3-inch conduit. Therefore, the minimum length for this dimension is 24 inches (3 x 8). Since the largest size raceway for the top/bottom (vertical) dimension is a 2-inch conduit, the minimum height of the box is 16 inches (see Figure 3). Step 2: Determine the total cross-sectional area for all conductors 500 kcmil THHN = 0.7073 sq. in. x 3 wires = 2.1219 sq. in. 250 kcmil THHN = 0.3970 sq. in. x 1 wire = 0.3970 sq. in. 3 AWG THHN = 0.0973 sq. in. x 1 wire = 0.0973 sq. in. 2.6162 sq. in. Step 3: Size the PVC raceway at 40% fill using Table 4 of Chapter 9. FMT is a raceway, but not a conduit and is described in a separate NEC Article 360. It only comes in 1/2" & 3/4" trade sizes, whereas FMC is sized 1/2" ~ 4" trade sizes. NEC 360.2 describes it as: "A raceway that is circular in cross section, flexible, metallic and liquidtight without a nonmetallic jacket." Electrical Metal Tubing (EMT) conduits trade sizes and max distance between supports Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications! i.e. Instead of saying the dimension you just say Trade size 1 meaning 1" conduit. It is intended as a way to use common language when writing. Since using a conversion from metric to inch you can sometimes get a different answer, using trade size should guarantee you get the correct size. Hope this helps. Richard S. Anderson, RCDD CDT CDCT
