How does a circuit breaker know that the voltage is high or low and trip off?
A circuit breaker doesn't respond to excessive voltages, but to excessive currents (overcurrents). A miniature circuit breaker, the type you have at home, has a bimetallic strip and a coil, either of which will initiate a trip in response to excessive temperature (overload currents) or excessive magnetic flux density (short-circuit currents).
Why isn't your circuit breaker staying on?
Assuming the circuti-breaker itself is working correctly, it's telling you there is a fault somewhere - either an actual short-circuit or your appliances etc combined are drawing more current than the circuit's rating. Do not ignore it, otherwise you run the serious risk of fire.
A 32A breaker was controlling a lighting circuit but is now on a 6A breaker which is now buzzing what should you do?
Answer for countries in Europe and other world areas running a 50 Hz supply service.Depending on the load of your lighting circuit. I would measure the current with an inductive amp meter. once you know the current required for your lighting circuit, you then install a circuit breaker which is 15% higher than your load. eg, load is 10A. 10A load + 15 % = 12A breaker (15 A is ok as the breaker is used to protect the wiring and should be rated in consequence of your wiring by 25% less or its current rating, or less, not the load)The humming of your lighting circuit breaker indicates that your breaker is either faulty, or having a difficult time keeping a closed circuit. Or simply that the manufacturer produced a breaker that hums by nature of its construction.
What must you do if a 25KW Power Distribution Panel circuit breaker trips and wont reset?
That means either there is a load (appliance or fixture) connected in the circuit that has a short and it needs disconnected before trying to reset. Or the breaker itself has gone bad and needs replaced.
Where isolators are placed in substation?
An isolator is a non load-breaking switch, and is provides a visible means of isolating a component, such as a circuit breaker, transformer, etc., from the high-voltage lines, whenever it is necessary to perform maintenance of that component. Normally, isolators come in pairs, with one on each side of the component to be isolated. Isolators are only opened afterthe load current has been broken using a circuit breaker, and must be closed before the circuit breaker is reclosed.To work on, say, a h.v. circuit breaker, the breaker must be tripped, the isolators on either side must be opened and locked off, temporary earths attached to either side of the circuit breake- to-work card, detailing the maintenance work, must be issued to the crew by the supervising engineer.
Where is the circuit breaker for a 2005 Chevy Venture?
which circuit breaker? either engine compartment or r.h. dashboard panel
What does the trip free characteristic of a circuit breaker mean?
A trip free circuit breaker is one that will disconnect a circuit even if the manual switch is held at the "on" position. It is a safety feature to prevent a circuit breaker being disabled either deliberately or accidentally.
Circuit breaker trip cause smoke will homeowner insurance pay for it?
A circuit breaker does not "cause" smoke. A circuit breaker "breaks" a circuit when there is too much current, creating a hazardous condition for the wires that are connected to the circuit breaker. The circuit breaker PROTECTS you from electrical fire. Find the source of the smoke; what burned? If a circuit breaker tripped during the incident, it is usually caused by melting/burning wire insulation, either inside or outside of an appliance. If the insulation inside the walls of your house has burned/melted, it could be that the circuit breaker was too large for the wire or that the circuit breaker failed to shut off at the appropriate current load. If the circuit breaker failed, your insurance should help you. If an appliance overloaded the circuit, your insurance should help you. If someone connected an oversized circuit breaker, causing the wire to overheat, your insurance company may refuse to help you.
Why your electric dryer makes breaker hot?
If the circuit breaker to a dryer, or to any load, keeps getting hot and trips the breaker, then either the load is pulling too much current or there is a loose connection in the breaker or breaker panel. Either condition must be fixed to reduce the risk of fire.

Switch (mechanical or electrical), breaker or fuse.a switch
What is racking a circuit breaker?
Racking a ciruit breaker has no place in Home Electricity. It is a purely industrial or utility activity. It refers to the act of disconnecting an open (off) high voltage circuit breaker from both the electrical supply and the load by racking (winding, if you like) it out of an enclosure.Further AnswerRacking provides a method of isolating a high-voltage metal-clad circuit breaker (in the UK, typically 11 kV) from its supply and load circuits, and/or to provide earthing (grounding). Before racking, the circuit breaker must be opened, and this is usually ensured using an interlock system. Racking describes lowering a circuit breaker so that its bushings physically disconnect from fixed busbars/cables typically located above the circuit breaker. Once racked down, the circuit breaker can either be withdrawn to allow it to be maintained, or it can repositioned before being racked up to connect either the busbars or the cable to earth (ground).
Why do you use isolator on both side of circuit breaker?
Opening a circuit breaker merely interrupts the current flowing through that circuit. It doesn't remove the voltage from the circuit breaker. Isolators (called 'disconnects' in North America) place a visible gap between the circuit breaker and energised conductors, allowing work to be performed on the circuit breaker safely. The full procedure involves: 1. Tripping the circuit breaker (CB). 2. Opening both isolators. 3. Applying temporary earth (ground) connections on either side of the CB. 4. Placing barriers and warning signs around the CB. 5. Issuing a permit to work card to the maintenance supervisor.
Why are your 92 crown Victoria headlights going on and off?
It usually means that there is either a short in the circuit or the breaker is faulty.
Where is the circut breaker?
Circuit breaker. The circuit breaker should be near the pedals next to the door. It also depends on what kind of car that you have. But usually they are near the pedals by the door. They should be under the dashboard, in a little box. The instructions for them is either givin to you when you buy the car, or they are on the panel door for the circuits and stuff.
