No, that is not what is happening. The throttle capacity has nothing to do with the load. The load comes from the motor and any lighted cars on the track. Even though the throttle is rated at 5 amps, it will never draw more than the supply is capable and will not in itself create an overload. An overload would be caused only by too large of a “load” or a short circuit.
