If a circuit breaker in the electrical panel heats up, the cause may be overload, loose contact, weak terminal, wrong rating or a damaged circuit. Replacing it with a larger breaker can be dangerous.
Strong heat, burning smell, discoloration, crackling, repeated trips or unstable appliance operation mean the panel should be checked.
An electrician checks load, cable size, terminals, busbars, breaker rating and panel condition, then fixes loose contacts or replaces damaged protection safely.
