A 120 V general-purpose house circuit should have circuit breakers or fuses with values of?
The fuses and/or breakers in a home should be matched to the circuits. A qualified electrician can help you make the proper calculations.
Do not attempt repairs or modifications if you do not have adequate knowledge about electricity or proper electrical construction practices.
Mistakes can be fatal or at best, expensive. You can burn down your house or electrocute yourself or others.

Are fuses and circuit breakers designed in a way to protect people from shocks?
No. Well, not directly anyway. Fuses and circuit breakers are designed to protect electrical equipment, not persons, from damage due to overcurrents (overload currents or fault currents). By disconnecting such equipment, they are rendered safe. But the level of overcurrent that will trip a circuit breaker or cause a fuse to operate is usually significantly higher than the current that will cause electrocution. Anyone relying on a fuse of circuit breaker for personal protection is likely to be dead before that protective device operates!To protect people, there are special devices called 'residual current devices' (UK terminology) or 'ground-fault interrupters' (North-American terminology) which will quickly disconnect at very low values of currents -below those which will cause electrocution. Such devices or, rather, their features are sometimes incorporated into circuit breakers so that such circuit breakers will protect both equipment andpersons. Often, these devices supply circuits that terminate in outdoor socket outlets (receptacles), so that electrical tools, such as lawn mowers, strimmers, etc., can be used safely.For more information on how these devices are used, you should consult your country's electrical wiring regulations, as the requirements vary from country to country.
For circuit breaker what does it mean by AF AT?
AF refers to the ampere rating of the breaker frame and AT refers to the breaker trip rating in amps. These are not breakers that you would find in your home but industrial molded case breakers. The current trips can be changed out to different values all within the same frame size.
What is the meaning of 200AT-250AF in circuit breaker?
Oh, dude, 200AT-250AF in a circuit breaker is just the current rating and voltage rating. The "200AT" means it can handle up to 200 amps of current, and the "250AF" means it's rated for 250 volts. So, like, it's just telling you how much juice it can handle without blowing a fuse.
Why you are calculating average and rms values for ac supply?
We will always calculate rms value only since the average value of ac current or voltage is zero. So we are using rms values in the ac circuit to calculate the power and to solve an ac circuit.
The sum of currents across the resistors equals the currents through the source in which type of circuit?
In parallel circuit the current through the resistors are different in values depending upon the values of resistors. But the sum of the currents across all the resistors will be equal to the current through the sourcgsvg bdjasuhafyuhda
What is the meaning of 200AT 250AF in circuit breaker?
250AF refers to the ampere rating of the breaker frame and 200AT refers to the breaker trip rating in amps. These are not breakers that you would find in your home but industrial molded case breakers. The current trips can be changed out to different values all within the same frame size.
Why breaker only available in 63A80A and not in 95A?
I have never seen breakers with those values, what country are you in?
What is the difference between a combinational and a sequential circuit?
In a combinational logic circuit, the output(s) depend only on the present values on the input, not on any previous values. In a sequential circuit, the output(s) also depend on the previous values. A sequential circuit must contain a memory element (at least one flip-flop) to hold the state of the circuit.
Types of circuit breakers?
There are several type of circuit breakers now a day we are using these are as follows: 1. M.C.B. (Miniature circuit Breaker) Rating : 1, 2, 4, 6, 10, 16, 20, 25, 32, 63 Amperes 2. M.C.C.B. (Miniature current circuit Breaker) Rating : 10, 16, 20, 25, 32, 63, 100, 200, 250, 400 Amperes. 3. A.C.B. (Air Circuit Breaker) Rating : 400, 800, 1000, 1200, 1500, 1800, 2000 Amperes. 4. A. B. Switch (Air Breaker) used in High tension line. 5. SF6 Breaker (Contact break in the Sf6 medium) used in High tension line.

What is the formula for calculating current in a circuit when given the values of power and resistance, where i p/a?
The formula for calculating current in a circuit when given the values of power and resistance is i p/a.
Why do technicians label their circuit component values?
For exactly the same reason that the components are manufactured with differentvalues. The reason is that a circuit will work the way you want it to work only if youbuild it with components of certain definite values, and if you use other values thenthe circuit will not work.When you write or draw a description of the circuit, it's not good enough to say"hook up a capacitor here" and "put a resistor there". If their values are wrong,then the circuit either produces nothing or else it produces smoke.
To display voltage values on a panel voltmeter of a high voltage power line (69kv) what additional electrical equipment should be added?
To display voltage values from a high voltage power line (69 kV) on a panel voltmeter, a step-down transformer (also known as a potential transformer or PT) should be added to reduce the high voltage to a lower, manageable level suitable for the voltmeter. Additionally, appropriate protection devices, such as fuses or circuit breakers, should be included to ensure safety and prevent damage to the equipment. Proper insulation and grounding are also essential to safeguard against electrical hazards.
What meaning of 63at-125af in electrical parameters?
AF refers to the ampere rating of the breaker frame and AT refers to the breaker trip rating in amps. These are not breakers that you would find in your home but industrial molded case breakers. The current trips can be changed out to different values all within the same frame size
Does the current remains the same in a series circuit despite the different values if the resistors in the circuit?
current in series depends on values of resistors. more resistance less current will flow through and viceversa
For circuit breaker what does it mean by AF AT?
