I am curious what others are doing in this situation since I have stumbled across it on a few jobs. As you know the standard AIC rating of a disconnect without fusing is 10,000A. The available utility fault current is generally higher than this. When POCOS require a cold-sequence switch how do you handle? If you fuse the switch it can't be the SE point because POCO usually won't allow ground wires through the CT cabinet. If you don't fuse it, it is not sized to handle the available fault current. Current limiters are one option. Another is to fuse it and label it as the meter disconnect switch as stated in the NEC and then the first disconnecting means after the CT would be the service point. Thoughts? I don't really see any issues with the latter as long as it is labeled as such as the NEC suggests.
