1200 Amps is a huge breaker. Typical houses might have between 100 and 200 Amp service. Since this would have to be a very unique installation you would have to provide a lot more information before cost could be computed. You also have to indicate who is supplying the breaker which would be a significant cost on its own.
Not unless you change the wiring for that circuit. The breaker protects the wiring and if you install a 40 amp breaker on a 15 amp wire circuit you will have a fire in your home.
Hard to define... A four year old child has the strength to physically "make" a typical household circuit breaker, while a teen would be able to "make" a typical industrial circuit breaker. (The latter breaker being physically much larger than the former.) Circuit breakers have their "breaking capacity" rated in AMPS. A typical household breaker is rated at 20, 30 or 50 Amps. Industrial breakers might be rated at 500 amps or a thousand or even more. Hope this helps but if it didn't answer your question, please rephrase it and ask again.
A #10 wire has the capacity for 30 amps. No breaker larger than 30 amps should be used to protect the circuit.
I would suggest a 20 amp breaker. * Added - I would suggest a 25 amp breaker. A slight surge, depending upon what equipment is the source of the 17.3 amp load, should not result in circuit breaker opening. <<>> In North America, the electrical code only allows circuit loading up to 80% on a continuous load. A 20 amp breaker can be legally loaded to 16 amps. A 25 amp breaker can be legally loaded to 20 amps.
For typical residential house wiring 12 AWG wire is required for a 20 Amp breaker. If you change out the breaker for a 25 A breaker you would have to rewire the circuit with 10 AWG. In that case you could up the breaker to 30 Amps. All outlets and switches should be rated at the same voltage and current as the breaker.
Not unless you change the wiring for that circuit. The breaker protects the wiring and if you install a 40 amp breaker on a 15 amp wire circuit you will have a fire in your home.
For a 10 amp, 250 volt circuit, you should install a circuit breaker rated for at least 10 amps and 250 volts. A common option would be a single-pole, 10 amp circuit breaker designed for 240-250 volt applications. Be sure to check the specifications and compatibility with your specific electrical panel.
The maximum current rating for the circuit breaker is 150 amps.
Not a whole lot. Assuming that is 120 volt power, 1200 watts would be 10 amps. A standard breaker is 15 amps.
The maximum current rating for the circuit breaker that can handle a load of 40 amps is 40 amps.
The maximum current capacity of a circuit breaker rated at 150 amps is 150 amps.
The maximum current rating for the circuit breaker needed for a device that operates at 20 amps is 25 amps.
61 nano-amps is 0.061 milliamps or 0.000061 amps
It limits the current to the circuit at 20 Amps. If a load on the circuit draws more than 20 Amps the breaker will trip and interrupt the current to all devices on the circuit.
KA stands for kilo-amps, or thousands of amps. Thus a 2KA breaker means it will trip when the load exceeds 2,000 amps.
The continuous current draw on a 20 amp circuit breaker should not exceed 16 amps to allow for a safety margin. This helps prevent overheating and potential tripping of the circuit breaker. It is important to follow the manufacturer's guidelines and not overload the circuit.
The maximum current rating for the circuit breaker in this electrical panel is 60 amps.
