Can an AC circuit breakers be used on a DC circuit and will this give that circuit adequate protection?

Check the nameplate on the actual breaker. Some breakers are rated for AC or DC. If it doesn't specifically list DC on the nameplate, then no, you should not rely on the breaker to adequately protect the circuit.

∙ 9y agoIt is a great risk of fire. A DC breaker has an arc quenching mexhanism that breaks the more agreesive DC arc. AC breakers are not designed to quench a DC arc and therefore the arc can keep going and start a fire. I install sar electricity systems and this is a major priblem

What is the function of switch gear?
Switchgears control electricity. They consist of switches, fuses, and circuit breakers which can be used to disconnect machines from electrical currents. This may be necessary if one wishes to fix a device without risking electrocution.

What is a difference between 10KA and 22KA circuit breakers?
The previous answer is incorrect, and I would advise that user to not give out information if they are going to give completely misguided information. The interrupting rating of a breaker is the maximum current that the breaker is designed to handle, at the breaker's rated voltage, before damage will occur to the breaker. A breaker will trip at FAR LESS than the interrupting rating, but it is extremely dangerous to expose the breaker to any situation where it will have more than the rated interruption current. the breaker is designed for. The reason some breakers are rated at 22kA instead of 10kA is because they typically have far larger conductors hooked up to them, so with the lowered impedance on the circuit there is more of a chance for the breaker to experience a higher fault current at the breaker. So electricians install 22kA breakers to handle the higher "available fault current."
Can a fuse protect against overloading?
The simple answer is NO.If this question is in reference to GFCI breakers the breaker trips when the deference in current going out and comming back is greater then .005 amperes.AnswerThe answer is YES. But fuses are designed to protect equipment, not humans, against overcurrents -including ground-fault currents. GFIs (ground-fault interrupters), however, are designed to protect humans from ground-fault currents.
In a 220 volt AC single phase circuit the voltage from either leg to the neutral is?
The proper terminology is L1,L2,N. N is for neutral and it is this wire that is grounded. The voltage measurement from the L1 to N will give you 120 volts. Also from L2 to N will give you 120 volts and as you know from L1 to L2 will give you 240 volts. Single pole breakers in the panel board starting at the top, alternate between L1 and L2 all the way down to the bottom. These breakers all have 120 volt outputs. If you plug a 2 pole breaker into two slots then you get 240 outputs because L1 and L2 are adjacent to one another.

How do you add circuit breakers to a 200 amp panel that is already full?
You can buy what are called Tandem circuit breakers. These only take up one space but allow you to connect 2 individual circuits to it. For example, say you had 4 - Single pole 20 amp breakers taking up 4 spaces. You could buy 2 - 20 amp Tandem circuit breakers and that would give you 2 additional spaces in your electrical panel. Just add up all your amps that your circuits will be pulling at one time to make sure you won't be overloading your electrical panel. One drawback to these Tandem breakers is that they are rough on your wallet. They are pretty expensive compared to regular breakers. Hope this helps

Will circuit breakers be damaged when installing dimmer switches?
No. Installing dimmers should have no affect on breakers. Be sure to turn the circuit off before doing this project.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
What size breaker is needed for a appliance with sixty amp draw?
This type of question usually means you aren't ready to do this yourself. Study some electrical material and the National Electrical Code and work this answer out for yourself. If I were to give you an answer, you might attempt to do something you shouldn't be doing, and that may cost someone a shock, a home fire, or their life. I will say this: the NEC covers circuit breakers in Article 240, Overcurrent Protection.

How does neutral missing protection work in single phase energy meter?

How can you tell if a house has GFCI breakers?
GFCI breakers are required by electrical code for all new and modified residences post 1984.Ground Fault Circuit Interrupters detect extremely small current fluctuations on the return side Neutral / Ground and cause the circuit to trip. Highly important in moist environments.To answer the question: GFCI breakers are required in all bathroom, garage and external outlets. To determine if it is a GFCI there will be a switch in the center typically of the outlet that says set/reset. Multiple outlets in a garage or outside may be wired in parallel and controlled by a GFCI breaker located in the main power panel. Remember use of a non-GFCI outlet in a moist environment is courting trouble and you or someone else may be the recipient.Answer for USA, Canada and countries running a 60 Hz supply service.GFCI breakers are not required. GFCI protection is required and you may choose whether to install GFCI breakers or GFCI receptacles. GFCI breakers, just like GFCI receptacles, will have a Test button. The breaker also will have the neutral attached to it on an appropriate terminal and an additional wire carrying the neutral current to the neutral bar.GFCI protection is required in all bathrooms, garages and other unfinished portions of a house including crawl spaces, unfinished basements, outside, and anywhere within 6 ft of the outside edge of a sink. -- SparkfighterAs always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
How to bypass single phase circuit breaker?
You should never try to bypass any protection devices. This is just asking for trouble down the road. The circuit breaker is there to protect the wiring to the device that is powered from that breaker. If the load is too large and keeps tripping the breaker install a larger breaker with new wiring sized to the breaker to accommodate the higher load current. Again do not bypass circuit breakers as you will have no short circuit or overload protection.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliancesalways use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
