15 amps is a fairly standard RV or caravan hook up and at 230 volts allows the use of appliances totalling around 3kw so as long as you don't exceed that amount your breaker should be fine, depending on what type of breaker is being used and which one is tripping...
The main breaker is probably an RCD (residual current device) that monitors the current flowing in the supply and matches it against that flowing in the neutral - if there is an imbalance it will trip. An imbalance can be caused by someone receiving an electric shock or current leaking away to ground due to faulty wiring or a faulty appliance.
If this is tripping it is not caused by an overload but by a fault! Similarly if the main breaker is an ELCB (earth leakage circuit breaker) and is tripping it will also be because of a fault.
Consumer units aren't often fitted with fuses these days and instead mcb's or micro circuit breakers are used and these will trip in response to an overloaded circuit or a short circuit.
I suggest you familiarise yourself with your equipment in order to decide what action to take.
I believe it is supposed to have a 15. Remember, breakers are installed TO PROTECT THE WIRE, NOT THE EQUIPMENT. If a breaker is tripping you just don't put a bigger breaker. The wire must be the correct size for the breaker. Take it to the manufacture.
