The answer to 'my fuse box won't turn on' is that there are several common causes, including a tripped circuit breaker, a blown fuse, or an issue with the electrical panel. Symptoms may include no power to certain outlets or appliances, flickering lights, or the fuse box not responding when you try to turn it on.
Some potential solutions include resetting any tripped circuit breakers, replacing any blown fuses, or checking for loose or damaged wiring in the electrical panel. However, if you're not comfortable working with electrical systems, it's best to call a licensed electrician to diagnose and fix the issue safely.
