I have recently changed my attic to be my bedroom, the attic wasn't designed to be lived in so there are only 2 outlets. I have a 500 watt PC, portable AC, aquarium heater and heating bulb and much more distributed across the 2 outlets and I think that is what causes the breaker to trip. Will adding extra outlets to distribute the load fix this issue and if not is there anything I can do to fix this?
The simplest solution would be to find out if the circuit that is tripping has other receptacles in another part of the house with loads that could be removed or transferred to another circuit. Modern room a/c units may draw as little as 4 A continuous (but more on starting) so the tripping may be resolvable by shifting loads in other rooms. There may be receptacles in 2 or 3 other rooms on the same circuit as the receptacles in the attic.
Next in complexity would be to rewire by tying into an existing circuit on a different breaker than the one now in the attic which is currently under utilized by the load on it. This would power an additional receptacle or two.
However, if there are open slots in your electric panel you could add an entirely new circuit and take it up to the attic. This has the advantage that you could bring a nice 20 A circuit up to the attic to take the load.
