What cause other than circuit breakers which are okay would result in electricity failure?
Most commonly, a loss of circuit continuity by: A) Disconnected phase wire. B) Disconnected neutral wire. These wires can become disconnected or loose when jarring faulty receptacles, wire nut connections, etc. The way we usually troubleshoot these issues is to attempt to check each receptacle in sequence. The circuit is broken when we get to the first receptacle that does not work. The problem usually lies in the actual receptacle not working, or the working one immediately previous to the faulty one.
How do you adjust an adjustable temperature limit stop?
To adjust an adjustable temperature limit stop on a faucet or shower, you usually need to remove the handle or cover to access the limit stop mechanism. Once you locate the limit stop, you can turn it clockwise to increase the temperature limit or counterclockwise to decrease it. Test the water temperature after making the adjustment and readjust if necessary.
How much do the ENIAC wires weigh?
The ENIAC, while not all the information is available, had about 70,000 resistors, which are small electronic components. Considering their size and standard weight, the total weight of all the wires in the ENIAC is estimated to be around 7-8 tons.
When do you need to replace the main electrical service?
You may need to replace the main electrical service if the existing system is outdated, damaged, or unable to meet your current electricity demands. Signs that it may be time for a replacement include frequent electrical issues, flickering lights, tripping circuits, and outdated technology that poses a safety hazard. An electrician should assess the system and recommend a replacement if deemed necessary.

How long does food last without electricity?
The duration that food can last without electricity can vary depending on the type of food, temperature, and storage conditions. In general, perishable items like dairy, meat, and leftovers can be safely stored at room temperature for up to 2 hours. After that, it is recommended to discard them to avoid the risk of foodborne illness. For longer storage, consider using a cooler with ice packs to help preserve perishable items for an extended period.
The Ground and Neutral wires have been wrongly connected somewhere before reaching the light fixture. The whole run of the circuit from the breaker panel to the light fixture must be checked so that the wiring fault can be corrected. : IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

If you do this work yourself, always turn off the power
at the breaker box/fuse panel BEFORE you attempt to do any work AND
always use an electrician's test meter having metal-tipped probes
(not a simple proximity voltage indicator)
to insure the circuit is, in fact, de-energized.
Why does your socket have a blue flash?
A socket should not make blue flashes. You may see one little blue flash when you first plug or unplug a device but anything more than that is not acceptable. The blue flash is called an electric arc. It is electricity jumping through the air. This spark is hot and is the reason for many house fires.

Why does the red reset button in the garage pop out when you plug in a refrigerator?
If You Had Provided More Information As To The Red Button, It Would Be Easier To Help You. Since You Mentioned A Hairdryer, I Will Assume This Is In The Bath. Also Since Your Mention Of A Hairdryer And A Red Button I Also Will Assume You Have A GFCI Recptical. This Will Have A Little Black Test Button & A Red Reset Button. If This Is The Case. You Are Overloading The Circuit { This May Be Due To The Way The Wiring Was Ran. And Again Your Ground Fault Recptical May Be Bad. ) That Is +++++++++ If We Are Talking About The Same Thing. Remember You Have Circuir Breakers In You House Also. These Are In Your Electric Control Box Where The Main Breaker Is. If This Isn`t Enough Info. Please Ask Question Again Providing More Info. But It Sounds Like You Are Overloading The Circuit. If It Is OK Without The Hairdryer On, Put It In Another Recptical. Also Your Circuit Breakers Can Go Bad. There Is Just To Many Things With So Little Info. Hope This Don`t Mess You Up If you are referring to the little red button on the outlet your hairdryer is attached to, it is a GFCI (Ground Fault Circuit Interrupter). The little red button should only trip if water, such as dropping it into the bathtub, interferes with the circuit. If you are referring to such a device on your bathroom electrical outlet, there should be absolutely no relation to any other circuit, including outdoor lighting. In that case, a liscensed electrical contractor should be consulted.
What should you do if a circuit breaker feels spongy and won't reset?
Some breakers must be turned all the way to the OFF position after they have tripped.
Before you spend a lot of money, just flip the breaker all the way to the off position THEN try to turn it back on.
Other answers
If this circuit breaker is a GFCI or RCD and it won't reset when you press its RESET button, it is doing its job.
It is telling you there is something wrong in the circuit it is protecting.
It may be a fault within an appliance (or its flexible cord or its plug) that is plugged into a socket outlet on the circuit being protected by the circuit breaker.
To find out, disconnect all appliances on the circuit and then press the RESET button. If the breaker no longer feels spongy then you know if is not a fault in the circuit wiring.
Then press the TEST button on the breaker. If it immediately trips then you know that the breaker itself is not faulty.
Then press the RESET button again and re-connect one appliance at a time until you find the one that causes the breaker to trip off. That is the appliance (or its flexible cord or plug) which has a fault that is causing the breaker to trip. The fault will have to be repaired - or the appliance will need to be replaced - before the circuit breaker can be reset with that item connected to the circuit.
Sometimes a fault can develop inside a socket outlet and there is now a "Neutral-to-Ground" short, or even a "Live-to-Ground" short, in the wiring to the outlet. Usually such shorts occur in the wall box behind the outlet because the wiring was done carelessly. Such a fault will also prevent a GFCI or RCD from being reset. That kind of fault must be fixed before the circuit breaker can be reset.

If it is a regular circuit breaker it might be that the breaker is mechanically defective.

How did they cook without electricity?
Our early ancestors cooked over an open fire just outside the cave's entrance. When man started building houses, the fire came indoors in the form of a wood burning stove. Later on, the wood stove gave way to coal fired stoves to cook on. On the invention of electricity the coal burning stove gave way to electrical appliances.
Gas used in lightened signs to produce a red color?
The gas used in lighted signs to produce a red color is typically neon gas. Neon glows red when an electric current is passed through it, making it a popular choice for producing vibrant red light in signage.
How do you read breaker box amps?
The main breaker will have marking indicating size of electrical service, or if it is a fuse system....the fuses will have current ratings. If it is a subpanel, it might not have a main breaker. In this case you would have to look in the panel that the feed is coming from and find the size of the breaker that is feeding it. In either case you must look for the manufacturer's label that will have the maximum current the panel can handle, make sure the breaker feeding the panel doesn't exceed this rating.
How many amps is used for a 60 watt bulb requiring 12 volts?
Five. An amp (C/S) is a measure of Coulombs (C) per second (S). A coulomb is a quantity of electrons, so you can think of this as the # of electrons passing a point on a wire, like the flow of a river measured in gallons per second. A volt (J/C) is the amount of energy, measured in Joules (J), per Coulomb. Finally, a Watt (W = J/S) is the measure of energy (J) per second (S). That's why a higher wattage bulb is brighter and hotter... it's using more energy.
Therefore, Amps = W / V = (J/S) / (J/C) = (J/S) * (C/J) = C/S = 60/12 = 5
What are 10 disad vantages of electricity?
- Electricity can be dangerous if not handled properly, leading to electric shocks or fires.
- Reliance on electricity creates vulnerability to power outages, disrupting daily activities and causing inconvenience.
- Electricity generation often relies on fossil fuels, contributing to air pollution and climate change.
- The infrastructure required for electricity distribution can be costly and prone to failure.
- Electromagnetic fields produced by electricity can have potential health risks.
- Access to electricity is not universal, leaving many people without this essential resource.
- Electricity production requires the extraction of natural resources, impacting ecosystems and biodiversity.
- The production and disposal of electronic devices can lead to environmental pollution.
- Electricity consumption contributes to energy consumption and can strain resources.
- High electricity bills can be a financial burden for individuals and households.
Does the size of a light bulb affect its energy use?
Not The size... its the Watts. The more watts you have the hotter and more energy it uses. Unless you go with LED. They are a lil expensive right now but will cost less to run, and last years.
Why do some lights go off in your house when you turn on too many appliances?
In a well designed house the lights are not connected to the same circuit as an appliance. If by going out you are saying that a breaker trips, then your appliances and lights combined are exceeding the rating of the breaker. You either need to rewire and balance the loads better or plug high current appliances into different outlets on another breaker. If you are not tripping breakers, but lights are just dimming you have a bigger problem with inadequate current supplying your house.
Why is the electricity supply 220 volts and not 200 volts?
220 volts is a common standard voltage for electrical systems because it allows for a balance between efficiency in power distribution and safety for electrical appliances. Additionally, the 220-volt system provides a higher power capacity compared to a 200-volt system, which is important for handling larger electrical loads.
Can you use non metallic cable in half inch electrical metallic tubing conduit?
No, non-metallic cable (such as Romex) cannot be used in electrical metallic tubing (EMT) conduit. EMT is designed to house and protect electrical wiring, so it is meant to contain only electrical wires, not non-metallic cables. It is important to use the appropriate type of wiring for the specific conduit being used.
How do you figure out resistance?
Turn off circuit. Then you can use a meter set for resistance, clip onto both ends of the resistor, meter will display the resistance in ohms.
If you know the voltage and amperage you can use Ohm's Law: E=IR
R=E/I
R is resistance, E is voltage, and I is current (amperage)
What voltage should read at the outputs of a hundred amp breaker?
It depends on where the breaker is fitted. Is it installed in a panel in the US, Canada or another country which also uses the 60Hz, 120 Volts standard supply service?
Or is it fitted in Europe or elsewhere using the 50Hz, 230 Volts standard?

The amperage of the breaker dont determine the voltage reading. If your panel is 120v every breaker regarding of amperage rating or size will still read 120v. but to answer your question as it reads... the voltage on the output should read the same voltage as the input or line side.. that is if the breaker is in the on position.
Difference between kw and kwh?
KW is the unit power KWh is the unit of electrical energy KW or Watt defines the rating or power of a electrical equipment. For ex: motors, heaters etc. KWh is a measurement that how much energy is been consumed by the electrical equipments. Generally, operating 1KW rated equipment for an hour measures one KWh. Energy meters are the instruments for this purpose
