You should be more careful.
Yes, it is called a circuit breaker. I dont know about your local regulations, but I have it for every room separately, and then some. If you already going to ask an electrician to install one just for your room, then please please please make sure to install a ground fault detection breaker also.
Or better yet, have an extra outlet with extra circuit breaker, GFD breaker, isolation transformer and everything. I dont know how old you are, but please understand that electronics can kill you in a second, and should be treated with respect and carefulness.
