Is my circuit breaker tripping because the supply line for my disposal is wet?
You can find out if the garbage disposal itself is causing the circuit breaker to trip by opening the electrical box under the sink that connects the garbage disposal and disconnecting the wires to the disposal (after making sure the power to this box is OFF). Cap the ends of the wires with wire nuts, then turn the breaker on. If it stays on, then its the garage disposal. If it still trips, then the problem is elsewhere.
