    Excellent information provided here in this video. I was able to fix the circuit breaker without have an expensive service call during extreme Texas weather in summer. Thank you very much for saving me money. 🙂

    Nice demo! Circuit breakers can "wear out."
    * The contacts can become worn or pitted, usually by using the breaker like a switch to turn on and off a load (some breakers are designed and rated for regular use as a switch) or by frequent tripping.
    * Frequent tripping, or even extended operating at high loads that are nearly enough to trip but not quite, with the resulting extended high temperatures in and around the bimetallic strip, can result in weakening of that spring and associated components to the point of eventual mechanical failure.
    * Some circuit failures can damage the circuit breaker. Such as surge loads that normally don't cause a problem, but which go dramatically higher during a failure. I wonder if something like that melted your copper braid?
    I had frying bacon sounds and smoke coming from my well pump breaker. The breaker failed to open so I braved the smoke and flipped the main. It burnt the pump breaker, its bus contacts, and the adjacent breaker. It was a Siemens 240 volt, 20 amp breaker for a submersible well pump installed in the late 1970s and the pump most recently replaced about 10 years before the incident. Startup surge on the 2hp pump was specified at about 14x the operating power. The lights went out one day due to a distribution fault (blowing the 7200v fuse on the pole is dramatic), and while the utility was finding the fault buried on our street, they isolated each of the transformers then started connecting them one by one. I'm the first transformer on the street, and when they connected me and turned on the power, the voltage was nearly 300 volt instead of 240 and I nearly had a fire in the breaker panel. However after a bit of rewiring, all was apparently fine for a few years. Last summer I did need to replace the about 15 year old well pump. It was shorted... I wonder if when the power came on it was in a locked-rotor condition, and the high voltage startup did not help.

      VERY common to have a poor connection between the circuit breaker and bus bar(especially older Challenger panels), I've fixed many over the years. Everything else you mentioned is accurate. Thanks for watching!

    This is a great video. I just had the no power issue with the breaker in the on position. I reset the breaker a few times with no success. Replaced with a new breaker and things are working again.

    Circuit breakers are designed to protect wire. Usually when a circuit breaker wears out it is because recently you may have changed a motor out for a new motor or replaced an oven or and very powerful microwave oven. Circuit breakers do wear out. Usually it is thermal protection part of the breaker that wears out over time because of the initial amperage draw.

      @@andyfer7716 The strip doesn't wear out, but the shape can change slightly over time if excessive loads have been placed on the breaker. Nothing lasts forever.

      @andyfer7716 3 года назад

      @@electronicsNmore Thanks. However, I would think that minor bending wouldn't appreciably affect the mechanism to the point of failure. It seems more likely that the melting of the copper wire (like in your video) would happen first.

      @iamanempoweredone6064 3 года назад +1

      @@andyfer7716yes it does. Every time the breaker trips on a thermal load it never bends back to the original/previous position. Over time the breaker eventually will not reset when tripped by a thermal overload.

    fantastic. Mine was even more less common which was the old one with the glass where you strew in with the viable fuse so that was pure thermal. LOL I put your video even faster speed to see the metal bend. interesting how they put just the right about of everything to trip at the exact temp... I assume. Unlike your other video fuse that tripped easily.
    I notice how they can vary in thickness despite the same voltage.
    Will you show the magnetic one or is it too much of a pain to deal with?
    Also the voltage in the homes are higher than 120 maybe 124 at times which wouldnt that be an issue in your option for higher bill or more stress on things? the electric company says its within 8% range and says its ok. hmmmm
    thanks

      I've swapped out screw in fuse panels years ago. I remember the time delay type. If this video starts pulling in views, I may do another showing the magnetic type. As of now, it's a big waste of time. YT is best at one thing, suppressing my channel.

    I used microwave last night and it went power off. I found out the outlet was not working because my toaster can't be switched on. Also, the outlet for my kettle doesn't work too (I plugged my kettle on the other outlet and it works). Then I checked my electrical panel and the breaker keeps tripping. So, do I just need to replace new outlets for both microwave and kettle? Or there's a problem on the breaker?

    the last segment that was a 15A breaker? what was Amp rating of the load?

      Yes, 15A breaker, and I was pulling around 20-22A.

  • @iamanempoweredone6064

    Most circuit breakers are designed not to trip up to 80 percent of their capacity. Anything above that , over time (minutes to hours) the breaker will trip.

    • @electronicsNmore
      @electronicsNmore  3 года назад +1

      That's true. If a load will be powered continuously, then you take 80% of the breaker rating as a maximum.

    I had a 20 amp breaker arc at the connection point to the bus bar while trying to turn it on; needless to say I'll be replacing that fuse. Any idea why this would happen; a faulty fuse, or perhaps a poor connection on the bus bar?
