Will a circuit breaker give off less amperage?
A circuit breaker does not give off amperage. A circuit breaker allows a flow of current up to the rating of the breaker. Any current higher than that of the breaker's rating will open the breaker's contacts and stop the flow of current.
Will a circuit breaker function properly if it is back fed?
Yes. The circuit breaker "does not care" which direction the current comes from. It is capable of protecting the circuit in any case.
Can you use any other brand of circuit breaker in conjunction with a Challenger circuit breaker?
A Murray or similar breaker would work but most inspectors want the brand breaker to match the brand panel.
What are the advantage of an oil breaker transformer?
I'm not aware of any device called an 'oil breaker transformer'.However, an oil circuit breaker or, more correctly, an 'oil-filled circuit breaker' is one of several types of circuit breaker used in high-voltage systems. The oil has two functions: (1) it is a far better insulator than air, enabling the circuit breaker to be far more compact (reducing its 'footprint'), and (2) the oil is used to extinguish the arc when the circuit breaker trips under fault conditions -a jet of oil removes ionised contaminants from the arc path, lengthens and 'snaps' the arc, and cools the arc.
Will cutler hammer breaker fit GE panel?
Cutler - Hammer manufactures two types of residential circuit breaker for the US. Type CH and type BR. The type BR will fit into most GE panels. It is probably a bad idea to use any other circuit breaker except the type listed on the label of the circuit breaker panel. GE panels require you to use GE circuit breakers. Using any other brand may put you at risk for liability if the installation fails and causes harm or damage.
Why shouldn't you connect two wires to one terminal?
If you are referring to a circuit breaker in an electrical panel, each circuit breaker is designed to trip at a preset amperage rating. The NEC (national electrical code) only allows one circuit, rated at no more than 80% of the breaker rating to be fed from each circuit breaker. Generally the builder will design the electrical layout of any building to maximize and to most effectively balance the load for lighting and receptacles. Adding another circuit wire to the load side of the breaker already in use could have a potential for overload which could cause the breaker to heat up and trip, not to mention that it complicates things during troubleshooting. New circuits or other wire additions must have their own breaker.
What is the requirement for energizing a 120 volt circuit breaker?
Before energizing a breaker for a circuit, the circuit has to be clear of any short circuits or grounds. This can be accomplished by the use of a megger on the correct voltage setting.
What is the smallest size circuit breaker found in the normal home?
The biggest circuit breaker in any home is the main breaker located in your main breaker panel that is installed where your electrical service cable comes into your home.
What would happenif you put an 8 amp circuit-breaker in a power circuit?
The circuit would be protected up to 8 amps before the breaker would trip. Any more that 8 amps and the circuit would open and shut the circuit off.
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."
Where to find a circuit?
Circuit breakers can be found in any circuit breaker panel. New circuit breakers can be bought at any shop that sells parts for installing or repairing electrical wiring circuits.
Need of isolator on both side of circuit breaker?
Before anyone is allowed to work on a high-voltage circuit breaker, it must be tripped, electrically isolated, earthed (grounded), barriers/warning notices put in place, and a permit to work document issued by an engineer to the senior member of the maintenance crew. 'Isolation' means a physical (and visible) break in the conductors between the circuit breaker and any potential source of supply -and this is provided by placing isolator switches on each side of the circuit breaker. Without these isolators, the circuit breaker would remain energized, even though the circuit has been broken by the circuit breaker.
