Arc Fault Circuit Interuptor. It is a breaker designed to sense an electrical arc that may cause a fire. It then opens the circuit shutting off the power and hopefully saving someones home.

When adding a ceiling outlet for a new paddle fan in the bedroom does the code required this circuit addition to be AFCI protected?
If you are planning on adding a ceiling outlet in the bedroom for a ceiling fan, code requires a combination type AFCI.
Can nm romex be used from breaker panel box to first afci outlet?
It depends on your local building code.
What is AFCI in electrical?
AFCI = Arc Fault Circuit Interruptor AFCIs are designed to sense the effects of an arc, such as when something is unplugged while running. They are technically required in any living area of a home but to my knowledge most local jurisdictions have not yet required them upon inspection. Check with your local inspecting jurisdiction to see what they require.
Can you safely install 3 prong plugs with old knob and tube wiring?
Install an AFCI breaker on the circuit with the outlets you replace and you will be fine.

What is the symbol for special-purpose outlets?
The symbol for special-purpose outlets can vary depending on the specific purpose. For example, the symbol for a GFCI (Ground Fault Circuit Interrupter) outlet is a rectangle with two vertical lines and a curved line inside. The symbol for an AFCI (Arc Fault Circuit Interrupter) outlet typically includes a rectangle with the letters AFCI inside.
What is a arc fault breaker?
All circuit breakers are designed to extinguish the arc created when the circuit breaker interrupts an electrical fault current. High-voltage circuits breakers use various techniques such as stretching and cooling the arc, and replacing the arc's path with a dielectric to prevent it from restriking.
Gfci outlet feels warm to the touch?
It is normal for GFCI breakers and receptacles to feel warm to the touch while under load. They should not feel "hot". GFCI receptacles often protect other receptacles further down the line, so the load does not necessarily need to be plugged into the GFCI receptacle itself. AFCI breakers will also feel warm to the touch. Again the receptacles should not feel "hot". If they are hot or heat discolored, you should discontinue use and call a licensed electrician. C.

What is the difference between an arc fault breaker and and a ground fault breaker?
A ground fault circuit interrupter is as its name implies, a device (circuit breaker or special receptacle) which interrupts (shuts down) a circuit when it detects a ground fault (current flowing to ground). When a small amount of current (4 to 6 milliamperes) is detected flowing to ground by the electronics within the device it trips so that no more current can flow, thereby possibly saving your life. Example: you are listening to the radio while having a bath and it falls into the tub--- the circuit will turn off before you can be harmed. GFCI's as they are commonly called are required by the Electrical Code to be installed in bathrooms, kitchens where the receptacle is within one meter of the sink, any outdoor location (rain and snow) and any other wet or damp locations. (refer to code book) An Arc Fault Circuit Interrupter is a device( I've seem breakers but am unsure whether there is a special AFCI receptacle) which shuts off a circuit when it detects an arcing condition in the circuit. An example of arcing would be when you pull the plug out of a wall receptacle when the device plugged in is under load (turned on) and you see a little (sometimes big depending on the size of the load) bluish or yellowish flash or "arc". Receptacles on AFCI circuit breakers are required by the electrical code to be installed in bedrooms. It has something to do with the flammability of linens and blankets I believe, but here again for detailed info please consult the official Electrical Code book for your location.
Can you use a GFCI on an unswitched circuit line red that uses the same neutral white for a switched circuit coming from the other phase line black in a 240v breaker panel?
Yes. You are allowed to use a neutral for one circuit from each phase of your service. For example, in a residential service, you can use the same neutral for circuits 1 and 3. In a commercial (3 phase) service, you can use a neutral for circuits 1, 3, and 5. You will experience problems if you use a neutral for two 'black' circuits or two 'red' circuits, if the circuits originate from the same phase bus bar. Also, AFCI's are sensitive to sharing neutrals, but GFCI's are not.
Can a regular electric cord be connected to an electric box so it works with a wall switch?
I would venture to say that almost all electrical codes would prohibit you from doing this, though technically possible. A cord-connected lamp is designed to be portable and typical lamp cord is not permitted to be used for a permanent connection. Removal of a cord-plug "disconnecting means" could also void the safety certification of the lamp (if any), making it more difficult to collect on fire insurance.Instead you should have an electrician add a switched outlet and plug the lamp cord into it. Not only is this up to electrical code, but is more versatile in the long run should you or someone else need to change out the lamp. Be aware that code now requires certain locations to have a GFCI for an outlet and most GFCI-integral outlets cannot be installed on a switch, so it would have to be a GFCI breaker on the circuit.Alternatively, your electrician can find a similar light fixture designed for permanent installation and wire that to the switch, with or without the switched outlet, possibly using "surface raceway". Without the outlet, no GFCI is required.Addressing some concerns it is capable to switch a GFCI outlet if the correct type is used and more of a concern than adding a GFCI is adding a combination arc-fault circuit breaker especially for use with lamp cords. If you decide on the second route of a surface raceway to a switch it is still recommended to add either a AFCI breaker or a GFCI breaker depending on conditions of installation. the most recent code changes to the NEC require that almost every outlet circuit (lighting or receptacle) be protected by either an AFCI or GFCI.
What type of electrical current is used to transmit electricity to our homes and workplaces?
Both series and parallel circuits are used in the home. If the circuit is a dedicated circuit which means that there is only one device in the circuit, then it is a series circuit. All the rest will be classed as parallel circuits.
