CBO
I inspected a new system the other day that used ground fault sensing via CT "donuts" on the dock pedestal feeders connected to a shunt trip breaker at the MDP. Where installed, the CT controllers did not have any visible settings on them to show that they were the required maximum 100ma per the NEC 555. The contractor did not know and none of the literature had this information, therefore I was unable to pass the inspection. They had to either remove the controller module or show me a spare which they did on a reinspection. I think the manufacturer should have this information where it is visible once installed. Here are some pics.
