Will turning off the main breaker turn off all the power to the circuit breaker box?

No. Power to all the circuit breakers will be cut off except for the Main power breaker. The Main power breaker (which supplies power to all other breakers and will say 100, or whatever your max breaker box power is, on it )will have power going to it all the time, unless power is turned off outside the house.

What is one and half breaker system in electrical lines?
One and half breaker system is an improvement on the double breaker system to effect saving in the number of circuit breakers. For every 2 circuits, 1 spare breaker is provided: Two feeders are fed from two buses via their associated circuit breakers and these two feeders are coupled by a third circuit breaker which is called tie breaker. During failure of any of the two feeder breakers, the power is fed via the breaker of the second feeder and main breaker (tie breaker).
Why gate circuits are isolated from the main circuit?
Gate circuits should be isolated from the main power circuit to avoid any damage to the power circuit if gate is damaged.
Will a circuit breaker function the same if supply and loads are reversed?
Yes, a circuit breaker will function the same if supply and loads are reversed. This is the way that some sub panels are fed instead of a main disconnect at the top of the distribution panel.
What are precautions to be taken at the time of back charging of generator transformer?
Nothing. If your system can run your house while the main breaker to the power grid is off, then back charging will occur as a byproduct while the main breaker to the power grid is on and you are using less power than you are generating. During times of a power outage, you'll want to cut the main breaker to the power grid, so that your system doesn't try to power the entire neighbor hood.
What makes a circuit breaker go bad?
A circuit breaker can go bad from being tripped too many times. Many people don't understand that the tripping of a circuit breaker indicates a problem that needs to be corrected. They usually just reset the circuit breaker, leading to a very common second (or third, or fourth) trip. Circuit breakers tripping are for the prevention of fire due to excessive heat in the circuit. They're not supposed to be tripped repeatedly. This can wear the breaker out. Believe it or not, I've also seen circuit breakers fail to re-energize after being turned off. I speculate this was actually caused by the breaker never having been cycled (it was a main breaker), and the time elapsed since it was installed. Electrical equipment doesn't last forever. It's the same as anything else.
Is there a circuit breaker that is operated by a signal sent down the same cable that's supplying power to it?
yes it is the main breaker
What is the rating of the main circuit breaker of the 60kw power distribution panel?
200 amps
Is the main circuit breaker is a sum of the sub circuit breaker?
Typically yes because that is what makes sense. However, the subpanel could have the same size breaker as long as the panel were rated for that amperage and the wire sizes were appropriate.
Why is the power off on on breaker when it is not flipped off?
Turning the breaker on allows the power to flow through to the outlets, lights, and appliances on that circuit, so yes power goes to and through a turned on breaker. If the breaker is off, but the main power is on, power still get to the breaker, usually from the bus bar that runs down the middle of the back of the breaker box.
What causes the main breaker to trip from a fault current from a twenty amp branch circuit?
If the fault was on the 20 amp branch circuit, the branch circuit breaker should have tripped, not the main breaker. Call a qualified electrician to check out your wiring.
What is the meaning of MCCB panel Electrical Engineering?
Main circuit circuit breaker
What are three main components that make up a circuit?
The power source, the thing it's turning on, and the wire to connect the power to the thing.
What is the smallest size circuit breaker found in the normal home?
The biggest circuit breaker in any home is the main breaker located in your main breaker panel that is installed where your electrical service cable comes into your home.
What prevents the main circuit breaker and the mission essential circuit breaker of the secondary distribution center from being energized simultaneously?
an interlocking device
Does an electric circuit have a beaker?
Electric circuit need a main circuit breaker that can protect the whole circuit from short circuit even in ground fault. It's safer if you use breaker with built in ground protection.
How do you tell if a wire is shorted out?
If by meaning wire as a circuit, when turning on the circuit the fuse will blow the circuit open, or if the protection is a breaker, the breaker will trip. This is all on the conjecture that there is a return path for the current to flow. This is the main reason for ground wires on all equipment, to provide a return path for the current to flow back to the source.
Where does power come into most homes?
It comes into the home from the electrical grid. It enters the home through a meter base and is fed into the service panel. This panel routes the electricity to each circuit in the home. Each circuit is protected by a breaker designed to trip and shut off power if the circuit becomes overloaded or there is a short in the circuit. A typical home will have a 200 amp service containing 40-42 separate breaker locations and one main breaker that shuts off power to the entire home.
