I am renting an old house that has been remodeled a couple of times. I don't know if the wiring is done correctly or not. I had one electician tell me that the owner needs to hire someone to come in and fix it. Well, here is my question: I have a dryer, a range, and the whole downstairs of the house wired to one 30 amp breaker. Is this safe or not? It has kicked the breaker a couple of times in the last couple of days. I am worried that this is too much overload on the breaker and what if by chance the wire gets too hot and melts the insulation causing a fire before the breaker kicks? (The downstairs along with the dryer are also all on an 8 guage wire to the 30 amp breaker.)
