<human>:  How do you prevent blackouts when doing construction?
<bot>: One way to prevent blackouts when doing construction is to ensure that there is a reliable source of power, either from an electrical generator or other energy source. Additionally, it may be necessary to set up an appropriate electrical system, using an electrician to ensure the proper wiring and circuitry are installed and functioning correctly. Having reliable protective devices, like circuit breakers, may also help prevent any blackouts during the construction process.
