The answer to 'why is my fuse box hot to touch' is that a hot fuse box is often a sign of an electrical problem that needs immediate attention. This could be caused by an overloaded circuit, a short circuit, or a faulty component within the fuse box itself. A hot fuse box is a fire hazard and should be addressed promptly by a licensed electrician.
Some common causes of a hot fuse box include too many appliances or devices connected to a single circuit, damaged wiring, a loose connection, or a problem with the fuse or circuit breaker. Symptoms may include flickering lights, buzzing noises, or the fuse tripping frequently. Do not attempt to fix the problem yourself, as this can be very dangerous. Instead, shut off power to the fuse box and call a professional electrician to diagnose and repair the issue.
