The answer to 'my electrical meter won't turn on' is that there are several common causes, including a tripped circuit breaker, a power outage, or a problem with the meter itself. If your electrical meter is not turning on, the first step is to check your home's circuit breaker panel to see if a breaker has been tripped. If the breaker is in the 'off' position, simply flip it back to the 'on' position. If the meter still doesn't turn on, it's possible there is a power outage in your area, so you can check with your local utility company to see if there are any reported outages.
If the circuit breaker is not the issue and there is no power outage, the problem may be with the meter itself. In this case, you'll need to contact your utility company, as they are responsible for maintaining and repairing the electrical meter. Attempting to repair or tamper with the meter yourself could be dangerous and may result in legal issues, so it's best to let the professionals handle it.
