After the last few jobs that required Arc Fault Current Calc's from the PoCo, my boss wants to know if there is some way we can fuse the wiring before or after the meter can that will take care of any arc fault issues, so we won't have to go back to the PoCo for more calcs.
I didn't bother trying to explain arc fault current to him, since he couldn't grasp why running wires sized for 500A to a wireway, then splicing (2) sets of 200A and a set of 100A wires with wire nuts wouldn't work.
So, aside from going back to the PoCo for more calcs, or severly up sizing the AIC rating of the panels, is there anything we can put in to take care of AIC issues, or should we go back to the PoCo. I'm thinking the PoCo would be the easy and cheap way, but not the fastest.
