70B is maintenance, NEc is installation, neither will address this. What is your real question? What happened? What tyoe of gear? What voltage? have pics?

Switchgear is 1984 Westinghouse 800A 480V/277Y 3P 4W Copper Bus.
The Vertical 800A Line Side Buss off the 800A Main Circuit Breaker was severely damaged do to a Arc Flash incident. The 800A Main Breaker is damage and the bussing damage beyond repair.
 
Contact Westinghouse or your supplier. That is by far your safest and best route to make sure the installation is safe. Sometimes there are local shops that build gear. It is possible if you have such a shop available to manufacturer replacement parts. This shop should be certified, this is where Zog or one of the others have more experience and may be able to assist you further.

Just curious - Who certifies shops for this type of work?

There is no certification, certification is a term that gets thrown around this industry quite a bit when in fact there are very few true "certifications", NICET and NETA are 2 of the very few. But I digress, that is another issue.

Remanufacturing of switchgear shoudl be done by a PERAL member company following the PERAL remanufaturing standards, only a few PERAL companies have the capibilities to meet the remanufacturing standards, most just do reconditioning. To remanufature parts for switchgear you must own the rights to the maunfautures original drawings and specs to the obsoleted parts. Obviously, companies that have this are rare.

Westinghouse what? They made about 10 different 480V 600A breakers/switchgear kines in 1984.

The Vertical 800A Line Side Buss off the 800A Main Circuit Breaker was severely damaged do to a Arc Flash incident. The 800A Main Breaker is damage and the bussing damage beyond repair.

Nothing is beyond repair, I do this stuff every single day. This to me is like installing an outlet to an electrician, routine.
