The answer to 'lifespan of fuse box' is that a properly maintained fuse box can last 25-40 years on average. Fuse boxes are designed to be durable, but their lifespan can vary depending on factors like the home's age, electrical usage, and any upgrades or repairs done over time.
Older fuse boxes made with outdated materials may have a shorter lifespan, around 20-25 years. Newer circuit breaker panels can last 30-40 years or more with regular maintenance. It's important to have a licensed electrician inspect the fuse box periodically to ensure it's functioning safely and efficiently.
