This is relatively easy if you are careful. However, you could kill yourself if you are not careful. Safety gear such as insulated rubber gloves, eye protection and rubber sole shoes all provide a margin of safety. Also have someone standing by to drag you away from a live circuit if you happen to get in trouble. Tie a rope to your belt for example. Now turn off breaker you are replacing. remove front panel of electric panel taking care not to touch anything inside panel. Once the panel is removed you expose live surfaces and wires. Make sure breaker is off. If in doubt check output with a volt meter. Put one hand behind your back and with a screwdriver in your other hand unscrew the screw holding in the black wire. Pull the black wire away from the breaker and make sure you don't touch it to any live black wires or the hot buss bar. Usually the breaker will pull out from the side away from the center of the electric panel. Usually there is a "c-shaped" clamp that clamps onto a retaining bar and another clamp on the hot buss bar. Lift breaker away from box. Insert new breaker and reconnect hot. Make sure breaker is off while re-inserting hot wire.
To turn off the main circuit breaker, locate the breaker box in your home or building. Find the main circuit breaker switch, which is typically larger than the others. Switch it into the "off" position to cut off power to the entire building.
I'm assuming this is a typical breaker you would find in your home. Pull the breaker to the off position, then to the on position. When the breaker blows on overcurrent, it will go to somewhere between the off and on position and open the circuit. From this position, you cannot force it to close (on position) without first taking it completely to the off position.
every circuit breaker has a overload release powered by CTs. Normal range is between 70 % to 110% of CT primary rating. find out overload conditions & adjust this setting. any more doubts email powercare1994@gmail.com
If you know what caused the breaker to trip then remove it from the circuit. Then open panel door and locate the tripped breaker as the one that is no longer in the full ON position. Some have a colored flag that appears when tripped. Now move the toggle to the full OFF position and then to the full ON position.
Find the electric meter. Any homes built in the last 50 or so years SHOULD have a disconnect (breaker) as a part of the meter base. Just flip THAT breaker and it should turn off all of the power to the home.
In the event of an emergency, local fire departments will cut the security tab on the meter base and pull the meter, cutting all power to the house. WARNING!!! That's actually illegal and you can get in BIG difficulties, so pulling the electric meter had better be only in the case of a real emergency... Like the house is burning down.
If your home does NOT have a meter base with a shutoff, you should contact a local electrician and have your electric service updated.
About the only maintenance you can do for a circuit breaker is to "exercise" it, that is turn it OFF, then back ON several times slowly. This should be done about once a year.

How do you replace a 15 amp breaker in the circuit box?
To replace a 15 amp breaker, first shut off the main power to the circuit box. Then, remove the cover of the circuit box and unscrew the old breaker. Disconnect the wires attached to the old breaker, connect them to the new 15 amp breaker, and securely screw it in place. Finally, turn the main power back on to restore electricity.
How do you hook up a 40 amp breaker panel?
To hook up a 40 amp breaker panel, first turn off the main power source. Then, connect the wires from the circuit breaker to the panel's bus bar, making sure to follow the manufacturer's instructions. Lastly, turn the main power back on and test the circuit to ensure it is working properly.
Why do you convert 120v circuits to 220v circuits?
Converting a 120v circuit to a 220v circuit can provide more power for appliances or equipment that require higher voltage to operate efficiently. This can reduce the risk of overloading the circuit and provide better performance for certain devices.
How do you get your Orbit Sprinkler Timer power off to power on?
To power off the Orbit Sprinkler Timer, you can unplug it from the power source or shut off the circuit breaker supplying power to it. To power it on, simply plug it back in or turn on the circuit breaker.
What would happen if a 240V breaker was on and someone attempted to turn on the clothes dryer?
There is a risk of electrical shock or fire if a 240V breaker is on and someone attempts to turn on the clothes dryer, as the high voltage could create a dangerous situation. It's important to ensure appliances are compatible with the voltage supply and that safety precautions are observed when working with electricity.

Why tap in your house gives shock when it is touched or used?
Your water system is not grounded. Turn the main breaker in your distribution panel to off and ground the water system. If a "hot" wire has come into contact with the plumbing, when you turn the electrical panel main breaker back on a breaker will trip. This will give you the circuit that is at fault and a place to start looking for the short circuit.
How do you hook up a 40 amp breaker panel?
To hook up a 40 amp breaker panel, first turn off the main power source. Then, connect the wires from the circuit breaker to the panel's bus bar, making sure to follow the manufacturer's instructions. Lastly, turn the main power back on and test the circuit to ensure it is working properly.
What would you do if the circuit breaker started started heating?
Turn the power off and call an electrician.
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.
How do you turn a 30 amp circuit into a 15 amp cicuit?
Replace the 30 Amp Breaker with a 15 Amp breaker.
Does a 1993 Suburban have a separate breaker for the turn signals apart from the flasher?
I'm not sure what you mean by "breaker". If you mean fuse, then yes, there is a turn signal fuse in the circuit.
What is circuit breaker and its type?
A circuit breaker(s) is what you will find inside your electrical box in your house the idea behind them is when a room in your house draws too many Amps the circuit breaker will turn off all the power to that room to re-engage them you simply switch it back on. There are many types of circuit breakers with different rattings like 15A or 100A, this tells you at what point they will 'break' the circuit and turn off the power.
How do you find out why a GFI won't reset if it tripped several times due to Christmas lights and rain but they are now unplugged and when the reset button is pushed it immediately trips?
If the outlet cover was held open by the lights it could be wet. A smal amount of water will cause a GFI to trip. A GFI is a device which makes certain that voltage is not draining away from the two wires, to some OTHER voltage drain, such as a human body or a wet circuit. if above not the answer go to your breaker box and find the breaker that controls that circuit. you will know when you have the right one when the breaker does nothing, not even trip it self. see what else is on that circuit {what else turns off when main breaker is tripped and unplug everything that is on that circuit then turn on the main breaker. try the reset with everything else off if it still trips then its the gfi itself. they go bad often on construction sites [my own personal experience] if it resets properly than one of the other things on that circuit is the culprit. replug or turn them on one at a time. the breaker will trip if its one of these. if not replace the breaker. pretty cheap at lowes or home depot. turn off main breaker when you replace it. lots of luck!!
Is it safe to turn on a 240 volt circuit after it has tripped the breaker?
It is safer to find out why the breaker tripped before the power is turned on. Turn off all equipment, then turn on the supply, then turn on each appliance one by one to find the culprit.
What should you do if someone have an electric shock?
Without touching the victim, remove them from the circuit. In the home, where the voltage is usually 240 volts or less, you can push them off with a wooden broom handle or pull them off with a rope. The moisture in those objects can turn them into conductors at higher voltages such as you might encounter in an industrial setting. The safest way to remove the victim from the circuit is to turn the power off at the circuit breaker panel or light switch. Go now and identify where your main breaker is. Don't forget that if you turn off the power at the main, your cordless phones probably won't work. Once the victim is out of the circuit, call emergency services and begin CPR.
Will turning off power to a ceiling fan via a wall switch be sufficient fro installing a new fan or must the circuit breaker be off too?
You need to turn off the power at the circuit breaker.
