I have a generator, what will happen during the meter exchange?

If the generator is installed correctly to automatically transfer the power source, there is a high probability of it starting. Most auto transfer generators look for loss of voltage for a designated period of time. For most residential generators this is between 10 and 30 seconds. If the generator does start it should only run for about a minute after the new meter is installed and the utility voltage is restored. If the generator is manual it will not start when the meter is exchanged.
