The San Onofre Nuclear Generating Station is being inspected after an emergency diesel generator failed during testing.Southern California Edison says the problem has been fixed and was likely caused by an improperly installed electrical component. But federal inspectors are doing their own investigation.

Officials with the U.S. Nuclear Regulatory Commission say the generator is designed to supply electrical power to the plant's safety systems if there's a power outage.

San Onofre supplies power to nearly three million homes.
