Fault Current Capacity

Fault Current Capacity

Fault Current Capacity

(OP)
I was trying to find out the fault current capacity of 1/0 copper, 2/0 copper, 4/0 copper @ 30 cycles.  For the use of choosing the right personal protective grounding equipment.

RE: Fault Current Capacity

Look at the conductor damage curves either in a software or manufacturer's publications.

RE: Fault Current Capacity

If you are using these for temporary grounding conductors, the bigger concern will be the withstand rating of the connectors at each end of the cable.  

I'd recommend buying complete grounding sets from A.B. Chance or similar (if you're in the US). These will have a tested and published rating consistent with IEEE standards for safety grounds.

RE: Fault Current Capacity

1/0 - 15kA - 30 Cycles
2/0 - 20kA - 30 Cycles
4/0 - 30kA - 30 Cycles

But DPC is right, the clamps are usually the limiting component, buy a full set that is tested and rated for your application.
