I made a request for a 10 kva transformer be installed. This was supposed to be a single phase trans., and by mistake the electrician started to install a 3 phase. He was going to feed it with 3 phase and then only run single phase to a disconect on the secondary side. We rejected the installation. What effect would this have on the transformer? I know it would be out of balance, but would the secondary output still have the same amperage. I know the installation was wrong, but would it still of worked if we didn't catch the mistake?
