Madison Co. Virginia | It sounds like they kept the same transformer. If so, the only possible mess up that could have happened was connecting one of the 120v legs to the neutral by accident.
Half of the circuits in the house would have simply been swapped hot vs. neutral. Those circuits and appliances will be fine.
The other half of the circuits were connected leg-to-leg instead of leg-to-ground. Those circuits would have been providing a 240v connection to anything connected to them. If the item wasn't turned on at the time, most likely, no damage would have occurred.
Most household wiring is rated for 600v. It won't short internally at 240v between conductors. | |
