The larger the AWG number or wire guage, the smaller the physical size of the wire. AWG, or American wire gauge, is a logarithmic stepped standard wire gauge that has been used since 1857 in the USA to define the dimensions of solid, nonferrous, and round electrically conducting wires. 46 inches (that’s almost a 100x difference). Dec 8, 2021 · Based on the 2017 N. 182 4. Wire size chart. 624. 4 conductor constructions are for three phase systems with one conductor being used as a ground. 93 6458. * = estimated values; normally, wire gages this small are not manufactured with these insulation types. 14 AWG to 1000 KCMIL, Sunlight Resistant, FT4 Flame Test Rating - (in all colours 350 KCMIL & larger) Contact Us. Quick Example: For a 10 amp 220V circuit, you can use a 20 AWG copper wire (because it has 11A ampacity). To be used at 15,000 volts or less and at conductor temperatures not to exceed 90°C for normal operation. Southwire® Type SE cable is constructed with sunlight resistant Type XHHW2 onductors or Type THHN/THWN conductors. 4 4/0 AWG RHH/RHW-2 building wire has XLPE insulation & annealed bare copper conductor.
