The cicuit braker should only trip when there is too much current running through it. Check to see what the braker is rated for (maybe 10 or 15 amps). Then take stock of what equipment is in that circuit (maybe a couple of lights?) and estimate how many amps the circuit should be drawing (maybe two or three). If there aren't a million lights plugged in to this circuit then chances are the light fixture in question is shorting out when you turn it on.

What could be the problem if a breaker trips when the light is turned off?

A short circuit in the wiring or in the switch.

What is an air circuit breakers?

circuit breaker is a switch that turned off when there is a short circuitAnswerAn air circuit breaker is a high-voltage circuit breaker whose tripping and closing mechanisms are (usually) operated pneumatically, and whose arc is extinguished by a blast of air -hence the alternative name 'air-blast circuit breaker'.

Can a Circuit breaker be used as a Switch?

Yes a circuit breaker is a switch but it should not be used as a switch. The continuous turning off and on of a breaker weakens the internal mechanism and reduces the tripping value of the breaker. There is in the marketplace breakers that are designed to be used as switches. These are usually used in large warehouses where the lights are turned on in the morning and shut off at night. Using these specifically designed breakers for switches does not wear out the tripping mechanism or reduce the tripping value. <<>> A circuit breaker can be used as a switch, although in most cases there are less expensive switches you can use.

How do you de-energize a circuit?

To de-energize a circuit, the voltage has to be cut off at the source. This is usually done with a disconnect switch which is located just before the circuit's load. Turning off the breaker on a distribution panel will de-energize the circuit it is feeding. To make sure that the voltage can not be turned back on when work is being done on the circuit, the switch or breaker must have a lock off device to prevent the circuit from being turned on, except by the person that locked the circuit off.

Could a bad circuit breaker light switch or plug outlet cause the bedroom light to flicker when turned on?

Yes a bad circuit breaker and a bad light switch can cause a light to flicker when its turned on. It could also be caused by loose wiring going or coming from that paticular circuit. it also could be something in the fixture itself causing. Checking for loose connections is your cheapest and first route to go.

Why did electricity along the line go out when switch was turned on?

Bad switch or a short and tripped the breaker.

A circuit with a switch turned to the Off position or a circuit with any break is called?

a closed circuit

Why do the headlights of a 1991 ford explorer go off and on when turned on?

The headlight circuit is protected by a self-resetting circuit breaker. Something in the circuit is drawing too much power and the breaker is cycling on and off.

When a switch in an electrical circuit is turned off what will happen?

The current to the circuit's load will stop when a switch in an electrical circuit is opened.

What is the difference if a switch is before or after a bulb in a circuit?

It is a safety concern. With the switch before the bulb, the bulb is completely isolated from the potential source when the switch is turned off. With the switch behind the bulb, even if the switch is turned off, the potential source is still at the bulb. If any of these lamp holder parts touch the ground when removing the bulb the circuit will short out and trip the breaker. If you are grounded and touch any of the lamp holder parts you will get a nasty shock.

What happens when you switch the light switch on or off?

When the light switch is turned on and a light bulb is connected in the circuit a current will flow through the circuit. Likewise when the switch is opened, the current will stop flowing in the circuit.

Electrical device in a circuit that opens or closes the circuit?

The electricity in a circuit can be turned off or on by a switch. A switch is a device that make it easy and convenient to open or close an electrical circuit.

Why is a torch switch important in a circuit?

So the torch can be turned on by the circuit being complete (connected).

Do you have a 15 0r 20 amp circuit?

Go to your distribution panel and shut off the breaker that you think is the circuit in question. If the circuit becomes de-energized then the breaker you just turned off feeds that circuit. Look on the handle of the breaker and the number you see is the amperage of that circuit. <<>> Determination of a 15 or 20 Ampere circuit is normally indicated by a combination of a 20A breaker and a 20A dedicated outlet. A 15A circuit normally has multiple outlets; not typical in a 20A circuit.

When a light switch is turned on what is done to the curcuit?

When a light switched is turned on the circuit is usually closed.

Does power go to a turned on breaker?

Turning the breaker on allows the power to flow through to the outlets, lights, and appliances on that circuit, so yes power goes to and through a turned on breaker. If the breaker is off, but the main power is on, power still get to the breaker, usually from the bus bar that runs down the middle of the back of the breaker box.

Can a switch in the off position cause electrical short circuit?

No, once the switch is turned off the circuit is de energized. A de energized circuit can not be shorted out to create a fault.

What would cause circuit breaker to trip in new box from old box?

A circuit breaker will trip if it is faulty or if the connected circuit has a short circuit or a connected device is trying to draw more current than the breaker rating. If you disconnect the output wire from the breaker and it still trips, it is a faulty breaker. If the breaker is tripping immediately when it is turned on then start disconnecting elements of the circuit to see what might be causing the problem. If everything was working and now isn't, it is likely that the wire from the breaker is nicked where it exits the box and is shorting to the feedthru connector.

Can you get electrocuted if the switch is off but the breaker is on?

Yes you can. The proper wiring of a switch is to bring the hot wire to the top of the switch terminal and connect the load to the bottom of the switch. When the breaker is turned off it disconnects the voltage from the top of the switch and the switch is then safe to work on. By not turning the breaker off, the voltage is present at the top of the switch which could subject you to a nasty shock if you come into contact with it.

What causes circuit breaker to trip even when it's properly rated?

A circuit breaker is dual function. The only time it will trip is if it senses a fault current that is rated higher than the breaker rating (short circuit). The other trip condition is if the circuit is overloaded and is drawing a current higher than the breaker rating. On breakers that protect motor feeders the breaker has to be rated 250% higher than the motors full load amperage. If the breaker has lots of use and is used for a switch being manually turned off and on will weaken the trip value of the breaker. If you have access to, or know an electrician, a clamp on amp meter on the conductor that the breaker feeds will tell you what is happening. Clamp the line and turn on the load to see exactly what the current is. If, like you say, the breaker is properly rated and the current is within the breaker limits then change out the breaker for a new one.

How do you make sure power is turned off?

if the switch in the circuit is switched off, the power is turned off on the object.

When you turn It off it breaks the circuit. When it is turned on it closes the circuit. To have a light bulb turn on it need to have continuity. Hope that helps

What is a closed circuit and an open circuit?

a closed circuit is a complete circuit with no breaks at all, one example:- a closed circuit occurs when you turn the light switch on an open circuit has a physical break in the circuit, which stops the flow of electrons. one example is when the lights are turned off, the switch creates a physical break in the circuit
