conductor clearance
(OP)
i have a question regarding minimum clearance between a bare conductor and structural steel with potential of ground.
The voltage is 300 VAC and the current is approximately 25kA @ 60hz. What is a safe distance between ground and this conductor?

One inch of (dry) air is adequate for a few thousand volts.

300 VAC
not sure

why is it bare? because it's a steel mill and the water cooled bus is up high.
just worried about arcing bus out if the structure becomes grounded.
