Can a 15 amp 240 volt circuit breaker be mounted in lower locations than the very top positions in the electrical panel?

Answer for USA, Canada and countries running a 60 Hz power supply service. On a electrical panel boards the wiring numbers go from left to right, top to bottom. There are 2 hot legs coming into the panel. L1 and L2. Breakers on L1 are 1,2,5,6,9,10. Breakers on L2 are 3,4,7,8,11,12. This is a 12 circuit board. This configuration allows every two adjacent breakers to connect to 240 volts. Example 1 and 3, 3 and 5, 5 and 7, 7 and 9, 9 and 11. Same with the even number side. So you see that a two pole breaker connects across the two hot legs L1 and L2 no matter where it is on the panel board. Any of these breakers on a panel board to the neutral will give you 120 volts no matter if the supply leg is L1 or L2. Just remember L1 to Neutral equals 120 volts, L2 to Neutral equals 120 volts, L1 to L2 equals 240 volts. So the answer to your question, it can go anywhere on the panel board where there are two spare slots.

Circuit breaker trip cause smoke will homeowner insurance pay for it?
A circuit breaker does not "cause" smoke. A circuit breaker "breaks" a circuit when there is too much current, creating a hazardous condition for the wires that are connected to the circuit breaker. The circuit breaker PROTECTS you from electrical fire. Find the source of the smoke; what burned? If a circuit breaker tripped during the incident, it is usually caused by melting/burning wire insulation, either inside or outside of an appliance. If the insulation inside the walls of your house has burned/melted, it could be that the circuit breaker was too large for the wire or that the circuit breaker failed to shut off at the appropriate current load. If the circuit breaker failed, your insurance should help you. If an appliance overloaded the circuit, your insurance should help you. If someone connected an oversized circuit breaker, causing the wire to overheat, your insurance company may refuse to help you.
Why shouldn't you connect two wires to one terminal?
If you are referring to a circuit breaker in an electrical panel, each circuit breaker is designed to trip at a preset amperage rating. The NEC (national electrical code) only allows one circuit, rated at no more than 80% of the breaker rating to be fed from each circuit breaker. Generally the builder will design the electrical layout of any building to maximize and to most effectively balance the load for lighting and receptacles. Adding another circuit wire to the load side of the breaker already in use could have a potential for overload which could cause the breaker to heat up and trip, not to mention that it complicates things during troubleshooting. New circuits or other wire additions must have their own breaker.
What is a Circuit breaker and explain type circuit breakers?
A circuit breaker is a switching device which can make,brake and carrying (or trip the circuit) that specified over currents for a small interval of time .
