How much you can use in 200A breaker?
200. Although you cannot exceed current ratings on any branch circuit without tripping that circuit. You need to make sure that you do not exceed 160 continuous load amps to meet NEC requirements of not overloading a breaker to more than 80% under continuous load.
Can you use Auxiliary contact with circuit breaker?
You need to be more specific. Do you want a contact telling you if a circuit breaker is on? If that is your question, the answer depends on the model of the breaker.
Is it true or false that a circuit breaker must be replaced after a short circuit occurs?
A circuit breaker must be reset to ON after a short circuit but does not need to be replaced. It depends on the type of CB. A fuse is also a circuit breaker and it needs to be replaced after a short circuit. Relayed circuit breakers have to be "picked up" after a dropout and need not be replaced as such.
How many ampacity rating do a circuit breaker need for the general purpose circuit?
Usually a 15 or 20 amp breaker is sufficient
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.
What circuit breaker to install for 10 amp 250 volt circuit?
You need a breaker rated for 10 amps and 250 volts. The breaker must also fit properly in your panel.
How do circuit breaker keep the wires in a electrical circuit from overheating?
A circuit breaker is designed to 'break' in a circuit if a short circuit (or other malfunction) occurs. This prevents overheating (or burn-out) of the circuit wires. In older systems, you would need to find which fuse wire has fused and replace it. In a circuit breaker, once the fault has been found and corrected, the breaker is simply switched back on.
What circuit breaker rating do you need for a 3 phase electric motor?
The circuit breaker is sized to the full load amps of the motor times 250%.
Does surge strips provide a built-in 15amp circuit breaker?
If the circuit breaker is in the off position there is no need of overload protection. Overload protection monitors the load amperage, If there is no amperage through the circuit there is nothing to monitor.
Can you replace a 20 amp circuit breaker with a 25 amp circuit breaker?
No. The breaker must protect the circuit components such as wiring, outlets and switches that are connected to the breaker. Therefore if you have a 30 amp circuit as dictated by its components you need to protect it with a 30 amp or less breaker.
Do air conditioners need there own circuit breaker?
Yes. Due to their higher current requirements it is recommended that air conditioners be connected to their own dedicated circuit and thus have their own circuit breaker.
Do you need a gfci outlet if you have a gfci breaker?
Not if the GFCI breaker is supplying the circuit you are wanting to put the GFCI receptacle into.
