The answer to 'lifespan of electrical meter' is that most residential electrical meters have an expected lifespan of 20-30 years with proper maintenance. Electrical meters are designed to withstand the elements and heavy use, but over time their internal components can wear down, reducing their accuracy and reliability. Factors like power surges, extreme weather, and general wear and tear can impact a meter's longevity.
It's generally recommended to have your electrical meter inspected and tested by a licensed electrician every 5-10 years to ensure it is functioning properly. This can help identify any issues before they become major problems. If your meter is older than 20-25 years, it may be worth considering replacing it to maintain accurate billing and avoid potential safety hazards.
