Where can you find a self resetting circuit breaker for 120vac 15amps?

If you are referring to circuit breakers used in residential or commercial building electrical systems, the answer is - you can't! What's more, you don't want to!
Circuit breakers are a safety device. A 14 gauge wire can safely handle 15 amps. If there is a short circuit, or if an appliance or appliances are plugged in that uses more than 15 Amps, the wires would overheat and could start a fire. The circuit breaker trips to prevent this.
The idea when a breaker trips is for you, the intelligent human, to go and look for the overload, and fix it before resetting the breaker. A mindless self-resetting breaker would just keep heating up the wire until a fire starts, defeating the purpose.
If you have a breaker that continuously trips, don't just keep resetting it. Find out why it is tripping and fix it or have it fixed! This could save your life!

How many all electric homes can be powered by a 20KW generator?
Do the math: Amps x Volts = Watts. Your house is mostly 120V and each circuit is usually 15amps (not counting large appliances).
60Hz is equal to how many amps?
The two are unrelated. HZ refers to the rate at which the electrical current cycles between positive and negative. Amps refers to the capacity for work that is available from a specific circuit.
How many amps does it take to trip a 15 amp breaker?
Depends upon the voltage, since P = I x E. If we were to assume 120 volts (typical in USA and a few other countries), and design load of 80 percent, you could safely supply 0.8 x 15 x 120 or 1440 watts. Of course, the wiring would also need to support 15 Amps or more.
Can a 30 amp double pole breaker be used to supply 15 amp breakers?
No, the number on the handle of the breaker is the maximum amount of amperage the breaker will handle before it trips. A two pole breaker is handling 240 volts. A single pole breaker handles 120 volts. Each of the "hot" wires from the two pole breaker has a potential of 120 volts to the neutral wire, but 240 volts from one "hot" wire to the other "hot" wire.
In a basement how many ceiling lights can you have on a 15A breaker?
for USA, Canada and countries using similar 60Hz mains suppliesUsing W=V*A, you can figure 120volts*15amps = 1800 watts. Typically you want to use around 80 percent of your capacity, so you are left with 1440 watts. You'd have to check the listing on your fan, but assume it uses around 400 watts at the very most. Your light fixtures will depend on the wattage of bulb you are using, so figure you can run 10 100 watt light fixtures in addition to your fan.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.In Canada there shall be not more that 12 outlets on any 2 wire branch circuit. Such outlets shall be considered to be rated at not more that 1 amp per outlet. Where the connected load is known, the number of outlets may exceed 12 providing the load current does not exceed 80 % of the rating of the over current device protecting the circuit.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energizedIF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
How many 15amps circuit required for a 6500va lighting load?
6500va divided by 120v is equal to 54. Then divide 54 by 15amps is equal to 3.8 (round it off, the answer is 4 circuits)
What is the meaning of the number 15 on a fuse or circuit breaker?
This is the amount of current that the wire in the fuse will "fuse" or open. and the Breaker will trip. Having said that, the time it takes to blow will depend on how close to the max the current is. If you put 13 amps on a 15 amp fuse, it will get hot enough to blow eventually. No fuse or breaker should have more than 80% load.
What circuit breaker acts as a switch creating an circuit when current is too high?
No. circuit breakers are in series with whatever lines they are protecting. They are never put in parallel with the protected loads (this would defeat the purpose). Circuit breakers open resulting in an open circuit / no power to outlets when they trip.
How do you size circuit breakers?
If you are using 14AWG wire in your circuit, you will fuse with a 15 amp breaker as 14AWG maximum amperage is 15 amps to 100 ft of wire. If the wire run is longer than 100ft, then you would fuse for 10 amps max. If you are using 12AWG then it can carry 20 amps, etc. Longer than 100ft you would fuse for 15amps. note: 14AWG is called 14/2 and 12Awg is called 12/2 commonly.

If a 120 volt appliance reqires 15amps to operate what is the resistance of the appliance?
The formula you are looking for is R = E/I.

Why a 15amps circuit breaker that has been installed for a new light line which has only 10 lights tends four of them turning off and on after some minutes?
There is bad wiring. Loose connection somewhere in this circuit. That or more load you don't know about. 10 100watt bulbs would only be 70% of the breakers rating. The 4 lights that are having problem might be where to start troubleshooting. Another thing to consider is that some lights have a thermal cut-out to keep them from overheating. Make sure the bulbs are sized correctly for the application to keep the lights from "cycling".See View Discussion belowAs always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.

Where is the headlight fuse on a 2008 HD softail?
The fuse block is under your seat. There is a black plastic rectangular cover with the fuse block schematic printed on it. The headlight has its own fuse, 15amps, which are available in auto parts stores.
