Re: Tie-breaker...
My diagram is not great but if you look at panels A, B, and C the tie-breaker is simply referred to as "Tie". The four tie-breakers were the added breakers in the 3 panels to allow for moving load off one power riser to the other in order to keep critical loads live during the installation of the UPS.
Most recent news is that in order to correct the problem of the misplaced breaker is to switch the conductors rather than physically move the breaker. This is to avoid another power shutdown. If work is ever done in that panel sometime in the future that requires a power shutdown then hopefully someone will remember to move the breaker at that time. In my opinion I would rather go through the pain of organizing a power shutdown now while the details of this mishap is still fresh in everyone's minds.
