The answer to 'how long does electrical meter last' is that a typical residential electrical meter can last 10-20 years or more with proper maintenance. Electrical meters are designed to be durable and withstand the elements, but their lifespan can vary depending on factors like the quality of the meter, the environment it's installed in, and how well it's maintained.
Proper maintenance, such as regular inspection and cleaning, can help extend the life of an electrical meter. If a meter is damaged or not functioning properly, it's important to have a licensed electrician evaluate and potentially replace it to ensure accurate electricity readings and billing.
