Why would power go off and on in 3 rooms and no circuit breaker tripped?

You have a loose connection somewhere. May be at the service panel itself. Check the circuit feeding those rooms at the breaker and check the neutral wire connection. If they are good these rooms may be feed out of a junction box which should be accessible if it was wired to code. Find that junction box and check all the connections. These are sometimes very hard to find.

What function does a circuit serve in your home?
it runs electricity to different rooms and regulates it. Has a max capacity and when reaches it it will trip or break. then you go to the Breaker and switch it back.
how many rooms are allowed on one lighting circuit?
Unless you do not have enough space in the service panel it is always a good idea to have each room on it's own circuit. If you want to put 2 rooms on a circuit just make sure those 2 rooms do not overload the circuit and wire it for a 20 amp circuit. Two bedrooms with 8 outlets each and 1 light each is about all you would want on the circuit. I would never put 3 rooms on the same circuit.
Why do you need a shunt trip breaker?
A shunt trip breaker is installed like any other molded case breaker. The only difference is that it has an internal tripping coil that is usually connected to a C.T. The breaker is usually mounted in a MCC cabinet The top of the breaker is bolted to the MCC bus bars and the bottom of the breaker is connected to the load. The load conductors pass through the C.T.'s which induces a current into the circuit to trip the tripping coil in the breaker.
What conduit is used in a residential residence with 15 amp wires?
You need no conduit on a residential home using Romex wiring with wooden studs. For a 15 amp circuit use 14/2 wire with a 15 amp breaker. This can only be used in bedrooms, living rooms, and dining areas. All other areas of the home require 12/2 wiring with a 20 amp breaker.
How many outlets are allowed on a 240 v branch circuit?
Branch circuit loading In Canada the CEC states that there shall be not more than 12 outlets on any 2-wire branch circuit. These outlets shall be considered to be rated at not less than 1 amp per outlet Where the connected load is known, the number of outlets shall be permitted to exceed 12, provided that the load current does not exceed 80% of the rating of the over current device protecting the circuit. For example on a 15 amp breaker, 15 x 80% = 12 amps, hence the standard of 12 outlets on any 2-wire branch circuit. On a 20 amp breaker, 20 x 80% = 16 amps. So from a 20 amp breaker this allows 16 outlets on a 2-wire branch circuit as long as the outlets are not considered to be rated at less than 1 amp per outlet. The definition of an outlet is a point in the wiring installation at which current is taken to supply utilization equipment. What this means is that if a light switch and a fixture outlet were on the same 2-wire branch circuit they would be subtracted from the maximum count of 12 receptacle outlets on the circuit which would leave 10. If the light fixture draws 3 amps plus the switch outlet, then the total circuit outlet count would be reduced to 8 receptacle outlets (12 -- 3 -- 1 = 8). On a standard specification home most electricians will wire one circuit per room, the outlet count usually never reaches the maximum of 12 outlets.
What do you do if the power is out in just about all the rooms in the house but the circuit breaker didn't trip?
You need to call the power company to come out and see what is wrong. Sometimes there is a problem with their equipment, burnt out transformer, etc.
If no power in bed or bath and no breakers are tripped and you already reset breaker for those rooms as well as main breaker butdidn't help No reset button on any GFCI's What should you be looking for?
If everything on the circuit is dead, I would start at the breaker box.Start with the simple stuff -trip and reset every breaker individually, not just the suspicious circuit or just the main. Sometimes, a breaker trips -but not to the extent that the tab flips to "off".If that doesn't work, leave the breaker on and, with a multimeter set to ACV, put one lead on the ground bar and the other on the screw head on the breaker. You should get a reading of 110V -if not 110V, then remove and replace that breaker.If you do get a 110V reading, the problem is an "open" in the circuit. Think of a circuit as a chain and the outlets/switches are the links. If a link is not connected, the remainder of the circuit (everything after the open) will not work. Start at the breaker box and trace the circuit to each of its connections at the switches and outlets. Remove the outlet/switch covers and peek inside the box to make sure the connections are secure. You can inspect the circuit with the power on or off. If you do leave the power on, use extreme caution while you're probing around -you might just find the open circuit the hard way!If you still don't find the open circuit, test each link (outlet/switch) separately, again starting closest to the breaker box.
Lost electricity to 3 rooms and you checked the circuit breaker and they are all in What else might be the problem?
Cable worked loose. Or there might be another breaker box somewhere else in the house, previously unknown to you.

When a home circuit breaker opens the lights in some rooms go off but the lights in some rooms stay on. Explain why.?
The circuit breakers in a panelboard feed separate circuits. The lights that stay on are on a different circuit than the ones that go off. To fine the circuit that feeds the lights that stay on, go to the panelboard and turn off the breakers one by one until the lights go out. This is the circuit that feeds that circuit of lights. Remember that lights and receptacles can be on the same circuit together.
Does it make a difference if you use multiple outlets in the same room vs using a power strip to feed everything into a single outlet?
In home wiring usually either all of a room's receptacles are on a separate circuit or two rooms share the same circuit. From the point of view from the circuit breaker there is no difference, the circuit will open when the breaker's limit has been reached. The advantage of having receptacles all around the room is for convenience, as different electrical equipment can be plugged in where the person want the device to be. The main reason to use a power strip is when more than two electrical devices are needed to be in close approximation with each other. A good example of this would be a component entertainment center.
How do you split 3 rooms on one circuit breaker into 3 separate circuits?
You would need two more circuit breakers in your main panel and run feed wires to each room. You would also have to determine where you could break the existing circuit for the two new rooms being rewired. How easy or hard this is depends on accessibility of the wiring for the rooms, such as in a basement or attic. This type of job will require skills in wiring and creating safe junction boxes. Don't even attempt if you don't know what you are doing.

Can you have multiple rooms on one circuit breaker?
It all depends on the load potential on each circuit. There are rules in the national Electric Code on how many outlets per 15 or 20 Amp circuits. As a worse case you will trip the breaker on a regular basis with more potential load. Also the wire size and devices must be compatible on both circuits.----------------------------Answer for USAThe code allows 2 wires connected to one breaker so long as the two wires are the same size and both are either stranded or solid, and not one stranded and the other solid. This prohibits the terminal from being tight on the larger wire and loose on the smaller wire. Many local jurisdictions do not allow this as it often involves this problem and shows a lack of professional workmanship.As for the word 'circuit', on any single pole breaker there can be only one circuit. Even if two wires are terminated, there is still only one circuit. It is no different than if you run one wire out to a junction box and branched off in two different directions from there. And running a single set of wires, hot/neutral/ground, out to a junction box and branching off from there is a more professional installation. It prohibits the look of poor workmanship in the panel and allows for the splicing of different sized or solid and stranded wires. All wires must be sized for the breaker as if it were the only wire on the circuit.When making modifications or repairs to older homes it is sometimes necessary to do what is necessary given the circumstances. Yes, I have landed more than one wire on a breaker. Yes, I have landed different sized wires on a single breaker. But you must be sure the wires are tight and not be guessing.Before you do any work yourselfon circuits, equipment or appliances,ensure the circuit is, in fact, OFF.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.

Just bought a house and two rooms have no power to the plugs breakers are all on?
Sometimes different types of breakers still look on even when they are tripped. The first thing to do troubleshooting this condition is turn off your breakers one at a time. Plug some sort of a device that will sense the voltage if it comes on, like a lamp. When you turn the breaker to the off position you should feel no resistance. If you come across one that has a bit of resistance about mid point continue to the off position and it should reset. Turn it to the on position and the circuit should be restored.
