In Georgia there are 2 classes of EC, restricted and non restricted. The resticted can't work on systems over 200 amps. I think when they came up with it, they meant residential and commercial/industrial, but they never thought you would commonly have houses with 400, 600, or even 1000 amp services. There are also 4 classes of low volt licenses, unrestricted, alarm only, fire systems only, and telecomm only. I currently have an unrescricted EC and I'm planning to get an unrestricted LV to have it all covered.
