This is a tough quiz without seeing the box. Your press is also confusing because you are saying a fuse box, but reporting a tripped switch. You any have fuses (round chalice fuses), or circuit breakers. What you are smelling, is something burning. Circuits/fuses are tripped when there is an overload. Have another being come out and look at the issue. Electrical issues are the LARGEST cause of house fires. The chain leading to the circuit/fuse may be burning up inside the box, within could be arcing from the breaker to the bus bar, etc. Tough ring from the internet.
