There are a few different ways. If there is a disconnect before the panel, it is usually labeled with it's max capacity or what the maximum fuses are, assuming it is a fused disconnect. If no disconnect is present, look at the main breaker for the entire panel. You can always check the main wires coming into your panel but opening a panel is EXTREMELY DANGEROUS and should only be attempted by a trained Electrician.
The term SN refers to a panel or disconnect switch that has solid neutral bar installed. It is a small bar that allows the service conductors to be bonded to the enclosure at that point.

The service distribution needs to have a disconnect from the utility supply. Most homes use a combination distribution panel. If the home owner wants to have a load center installed then there has to be a fused disconnect ahead of the panel. The less costly of the two options is the combination panel. Labour costs drive the load center, main service switch option much higher because there are more materials to assemble.
The main supply will first come from the power company to a transformer to reduce the voltage then from the transformer to the weatherhead then through the house meter to the main disconnect on the outside of building then to the switchgears main. The cable coming from the transformer to the meter and to the top of the main disconnect is the Main service cable
Yes. But the NEC requires that your first disconnect be installed as close as practical to where the service enters the building. So if the bedroom isn't where the service enters the home, you will have to install a stand-alone disconnect where it does and then wire to your panel.
Yes
A braided 3/4" stainless steel hose can be installed on cold and hot water line for a quicker disconnect.

Electic service was first installed in homes in the 1800's. This service quickly spread as more communities became wires for service.
