SO cable - Type W cable or Type G cable
In our last post we talked about the difference between SO cable and Type W cable. If you need something more robust than Type W you would then move up to Type G cable or Type GGC. The difference is the G has 4 conductors and the GGC has two or three conductors. Type G is similar to Type W in that both are 2000 volt rated and 90 degree C rated. However the W does not have ground conductors where the G has a ground conductor for every primary conductor as well as 2 additional grounds. Ground wire size depends on what gauge size the primary cable is.
For example if a cable is called out to be a 2 awg 3 conductor GGC the cable would have a total of three 2 awg conductors, two 7 awg grounds and one 10 awg ground check. In a 2 awg 3 conductors type W cable you would only have the three 2 awg insulated conductors.
