If you lose electrical power in your home, the first step is to call your utility provider. The outage may be caused by something temporary, such as bad weather, construction, or fallen lines.
If you're the only property impacted in your neighborhood, you may have tripped your circuit breaker. You can check to make certain this isn't the case by locating your breaker box and verifying that the lever is in the ON position.
If it's not in the correct position, move the lever to ON to restore access.
