| Post subject: | Fault Current |
I'm wondering if there's any data available that indicates the necessary available fault current, on a 277V system, to blow a hole through the sheathing of a MC cable (#12 awg, 3 conductor). Assume worst-case - a bolted fault either between phase/ground or phase/sheathing. If I know that necessary available fault current, I could then conduct a fault current analysis for my particular situation to determine if there's even sufficient current for that to hypothetically occur. |

There are formulas for metal damage but gas pressure will open it up before it melts through. |
