The answer to 'how long does fuse box last' is that a typical fuse box or circuit breaker panel can last 25-40 years with proper maintenance and care. Fuse boxes are designed to be durable and long-lasting, but they do have a finite lifespan. Over time, the internal components can wear down, connections can loosen, and the entire system may become outdated and less efficient.
It's important to have your fuse box or circuit breaker panel inspected by a licensed electrician every 5-10 years to ensure it is functioning properly and to identify any potential issues. Upgrading an older fuse box to a modern circuit breaker panel can also improve the safety and efficiency of your home's electrical system.
