Is there any problem with this HVL/cc lineup with 1200A main bus? The customer thought that the bus bars leaving the termination section were smaller than the ones downstream in the current flow. He wanted permission to energize as built and procedures to bring down the current density. Stated that the fixed bus concentrates about 1000A through two 5/16`` bolts. Is the OK?

Yes, the switchgear in OK as built. The 1200A HVL/cc switch is adequate to carry 1200A continuous without exceeding 65 degree C rise and withstand a 25kA rated short circuit current.
