I currently have an existing 3000 amp service rated switchboard. I am adding a second utility service as well as another 3000 amp service rated switchboard. I would l like to provide a tie breaker between the two switchboards but I do not know if this will nullify the UL rating or even if this can be done. The reasoning for this is so that if maintenance or new work needs to be done on either of the switchboards, the other one can carry the building load. If possible, I would like to avoid purchasing two switchboards.
