My question is if you’ve got a lighting circuit and you ad addition loads to the circuit will this always trip the breaker if you add too much load on a circuit?
In general, yes the breaker should trip before any damage results.
There are exceptions however if the original design or installation was of poor quality. For example 1mm cable on a 10 amp MCB is usually fine, but if large numbers of cables are bundled together and/or the temperature is unusually high, then the cable might become dangerously heated by an overload before the breaker trips.
