No! At this time I wouldn't have less than a 200 amp service for a 3 bedroom house. Keep in mind just because there is a place to plug "stuff" into doesn't mean there is enough capacity in the wiring to handle the load. Please call an electrician. The Fire Department call would be much more expensive.
Blown fuse or circuit breaker. Wires loose on another outlet in that run feeding that bedroom's outlets.
Depends on what the outlets are controlling, size of the wire, and size of the breaker.
Technically, they can be on a 15 amp breaker when you use 15 amp outlets. There is a difference. Be sure to check your local code (just call the city building department and tell them you have a code question). some cities require the bedroom outlets to be on an arc-fault breaker.
Depends on the size wire used in the circuit. If you wired the circuit with AWG #12 wire on a 20 amp breaker then you can install no more than 12 outlets. If you wired it with AWG #14 wire on a 15 amp breaker then install no more than 9 outlets. This is assuming only outlets are on the circuit and nothing else.
Two 20 Amp circuits with the outlets staggered so a different circuit is on two adjacent outlets. Should be GFCI protected.
Your home electrical wall outlets current capacity is governed by the breaker that feeds that circuit. In most home situations the wall receptacles are fed with a 15 amp breaker. Dedicated outlets could have a higher ampacity as they are installed for specific appliances or devices. To check your circuit, plug a lamp into the outlet. Start flipping the breakers off. When the lamp goes out that is the breaker for that circuit. Look on the handle of the breaker and it will tell you the capacity of that particular circuit.
The breaker panel. Breakers are placed in series with all outlets.
Somewhere you have a loose or broken connection.
No. The breaker must protect the circuit components such as wiring, outlets and switches that are connected to the breaker. Therefore if you have a 30 amp circuit as dictated by its components you need to protect it with a 30 amp or less breaker.
Wires could be disconnected from the main fuse box. Check to see if you have any Ground Fault Outlets installed and ensure that all have been reset. It sounds like they may all be on one circuit and if so, You need to check that all outlets nad light fixtures have good connections and are tight. Its possible that you have a GFI outlet in bathroom that is tripped or is bad the bedroom outlets are possibly wired to same circuit It just may be that the fault that tripped the breaker also broke the circuit to the other points. Look into the boxes of the outlets and switches. If there was a fault you may see carbon where an arc broke a wire to the remaining points in the string.
It would be quite unusual to have a single 60 amp circuit with outlets and lights. You would have to use very heavy wire to each light and outlet. Typical lighting circuits would be protected by 15 amp breaker and a circuit with general purpose receptacles would have a 20 amp breaker. A typical lighting circuit might have 10 to 12 fixtures and receptacle circuit might have 8 outlets. If you don't know how to size a circuit get an electrician.
For the 120 volt outlets on the wall use a 20 amp breaker wired with AWG #12 wire. The circuit must be GFCI protected. Any 240 volt outlets must be wired according to what they will be powering.
