The answer to 'difference between electrical panels' is that there are two main types of electrical panels: circuit breaker panels and fuse boxes. Circuit breaker panels are the more modern and common type, while fuse boxes are an older technology that is gradually being phased out.
Circuit breaker panels use individual circuit breakers that can be reset if a circuit is overloaded or short-circuited. This makes them more convenient and safer than fuse boxes, which use replaceable fuses that need to be swapped out when they blow. Circuit breakers also typically provide more flexibility to add or modify circuits in a home. However, fuse boxes can still be found in older homes and may be less expensive to install or upgrade.
