As far as a fuse like in a car or even larger versions of the fuses in a car you should be able to see inside the little wire; if the fuse has burnt amd is split in two parts the fuse has been broken. In a circuit breaker it works a little differently, instead of burning out and needing to be replaced, the breaker will "trip" this means there is too much current being drawn through the circuit and the setup cannot handle it. A breaker instead will click to the off position and the switch will flip from on to off. These are much easier to locate than a burnt fuse because in a breaker box usually all the switches are turned to on and in the same direction, so the one breaker that did trip will be pointed in the opposite direction. Simply flip the switch from off to on and its been reset. If the breaker keeps tripping then there is either a short or you have too many loads (appliances) running on that circuit, for instance a power strip with 6 things plugged into it all running at the same time.

∙ 11y agoit will be dead when others are not
there is usually some way to see that the breaker is tripped
or the fuse is blown
another reason fuses are safer
sometimes with circuit breakers its hard to tell a tripped one from one that has been turned off

∙ 14y agoLook for a breaker handle that is not full on and is misaligned with the other breakers around it. Switch this breaker to the full off position. You will find a bit of resistance as the handle is moved to the off position as the breaker resets. Move the handle to the on position and the power should be restored. If the breaker trips instantaneously when turned to the on position there is a fault on the line that must be removed.

What causes the main breaker to trip from a fault current from a twenty amp branch circuit?
If the fault was on the 20 amp branch circuit, the branch circuit breaker should have tripped, not the main breaker. Call a qualified electrician to check out your wiring.
The light on my gfi outlet is dim and sometimes out i am getting no power to it but the circuit breaker is not tripped i just replaced the gfi and it didn't help any ideas?
If the GFI outlet is tripped (the outlet, not the breaker) then it is telling you there is a ground fault which must be fixed. If the GFI outlet is not tripped, and the breaker is not tripped, but it is still not providing power, then you have a loose connection or a wiring error.
How do you find a triped circuit?
Check the circuit panel / breaker box. The tripped breaker should be partway between 'OFF' and 'ON'. If nothing else, turn the breakers off then on, one at a time and when the tripped breaker is reset, the circuit should be live again. Also check GFI outlets. If one is in fault condition, it will need to be reset. If the tripped GFI outlet is protecting other outlets, they will come back when the tripped GFI is reset. These sockets seem to hide in many cases... Behind microwave ovens for example or refrigerators.
How do you know if the circuit breakers are damaged when an electrical shock just happened?
If the breaker is damaged it will not reset to the on position. It will stay in the tripped position.
If your wall receptacle has tripped but not at the circuit breaker how can this problem be repaired?
If it's a GFCI receptacle and the button is not resetting then change the GFCI outlet.
In electronics what is meaning when a moulded case circuit breaker releases?
It is another way of stating that the circuit breaker has tripped due to an over current.
Possible electrical problem will my microwave oven be okay?
Check the circuit breaker to see if it tripped.

Will a circuit breaker be the cause of an air conditioner not turning on?
It is possible if the circuit breaker has tripped or is faulty. The best way to check is by unplugging the air conditioner, and plugging in a table lamp. If the lamp lights up, then you know that the circuit breaker is working, if not then it is faulty.

What would you conculde if you saw if one bulb burned and all lights fail?
The bulbs are in connected series. There was a short circuit and the circuit breaker tripped.
Is it safe to turn on a 240 volt circuit after it has tripped the breaker?
It is safer to find out why the breaker tripped before the power is turned on. Turn off all equipment, then turn on the supply, then turn on each appliance one by one to find the culprit.
You lost a voltage leg by connecting the ground wire to the circuit breaker but com ed wires are still energized?
Yes this could be true. The breaker to the load will have tripped. The main breaker should still be allowing voltage to the distribution panel because it did not trip. If the main breaker tripped then the distribution panel must have been close to maximum amperage and the shorting of the branch circuit was enough to trip the mains.

Why has your 3500 Honda single phase stop generating?
First check the obvious. See if the circuit breaker has been tripped.
How the circuit breaker differ in its function from combination switch fuse unit?
The function is the same in that they both are designed to remove an over current situation by opening the circuit. A tripped breaker can just be reset. A blown fuse needs to be replaced.
