Is it better to have a high or low resistance across a circuit breaker?
A circuit breaker is supposed to protect the more valuable component the circuit is connected to. Too low a resistance, a minor glitch (spike) will break the circuit and stop the device from working. Too high a resistance, no glitches, no matter how large (a child sticking a paper clip into the wall sockets, for example), will break the circuit and the device (child) may get damaged. Each circuit will have a purpose (power load), and the circuit breaker should be chosen for that purpose with some tolerance. A free standing closed circuit breaker should have no resistance across its internal contacts. The main purpose of a circuit breaker is to protect the conductors that supply the load. If the current going to the load becomes greater that the amperage rating of the wire the circuit will open thereby saving the conductors from damage. Once the load current is below the wire rating ampacity, the breaker can be reset for normal operation.
Circuit breaker are for the same purpose as?
... fuse.
What is the metal piece on the circuit breaker preventing it from tripping?
A circuit breaker is designed so that it will trip when the electric current is too high. That is the purpose of a circuit breaker. If there is a metal piece on the circuit breaker that prevents it from tripping, it is useless. Perhaps someone has altered it.
How do you work air circuit breaker?
There are various to check if your air circuit breaker working. You can use various tools that are available to test your air circuit breaker. A clamping ammeter is ideal for this purpose.
What is the purpus of a circute breaker?
The purpose of a circuit breaker is to protect electrical circuits from short circuiting.
What is the purpose of a Pushmatic breaker?
It is a residential circuit breaker to increase your circuit boards power. They are no longer widely available but they can be purchased from eBay and other on-line retailers.
What does a fuse or circuit breaker do when too much electricity flows through a circuit?
A fuse or circuit breakers purpose in a circuit is to disconnect the circuit load from the voltage source when a circuit fault occurs.
What is the basic purpose for using an electric panel?
The basic purpose of an electrical panel is to distribute the proper voltages and currents to the required loads connected to the electrical panel. Installed in the electrical panel are protective devices are known as breakers. Each breaker protects the load supply wire and does not allow the current to rise above the wires amperage rating. If the circuit load current does rise above the wire's ampacity, due to a short circuit in the load, the breaker disconnects the fault from the supply system and still allows the other circuits connected to the panel to operate without interruption.
How many outlets and lights on a 60 amp breaker?
120 amps The above answer is wrong. A 60 amp breaker is designed to trip at 60 amps be it a single pole, double pole or a triple pole that is used on three phase equipment. The number on the handle of a breaker is the trip capacity.
Which device provides short circuit protection?
A fuse protects a circuit from short circuiting. Also a breaker is used for this same purpose with the additional advantage of protecting the circuit from overloads also.
What is the Function of circuit breaker?
The purpose of a circuit breaker is to open the circuit in the event of an overload. Wires/conductors are only rated for a specific Amperage. If this amperage is exceeded the conductor/wire begins to heat up and given enough time it becomes a fire hazard. For instance a 15 amp breaker will trip once the Amps drawn through that circuit exceed 15 amps. The short answer is to keep you safe.
What is the purpose of a branch circuit?
To supply power to all electrical devices in a house, apartment, condominium, etc. A branch circuit is connected to the circuit breaker panel which is usually found in a closet or a cupboard
