Overload...

Well, it's been awhile since we've talked about these things, but I just found what I think is the circuit breaker for my apartment. At first I thought they were fuses, but they don't seem to have anything that is easily replaced and the switches go on and off. These switches turn off when the current going through the wires is too high. This is to protect the house from possible fires that could occur when too much current goes through a wire and burns it up. There are many switches because each one is in charge of the current flowing to a different area. I think this means that the system is in a parallel because that way one switch going off won't affect the rest. (Luckily, we've only had to use the circuit breaker once from what I can remember.)
