They may or may not be required for all living spaces where you live when upgrading the panel. Call your local inspector to find out. In my area they are not required on an upgrade but I always install them in bedrooms, closets, living rooms, den, sun room, breakfast room, dining room, libraries, any place people gather may require them. AFCIs will not be required in bathrooms, kitchens, laundry rooms, unfinished basements, garages, attics or outdoors. I personally install them when I upgrade a service panel. They are a great safety device that will protect the people living in that home. I also recommend and install GFCI outlets where needed if the homeowner agrees.

What fuses and circuit breakers provide protection in the event of?
Short circuit fault.
Why does the main circuit breaker trip but not the smaller branch circuit breakers?
If the main breaker has ground fault detection, and the fault is a ground fault, then only the main may trip. Also if the fault is a direct short, the fault current may be several thousand amps, much greater than the trip point of both breakers. Breakers have an I^2T curve (current squared-time), which is an indication of how fast the breaker will trip at a given overload. When both breakers are overloaded, the breaker with the faster I^2T rating at that current level will trip first. This would be an indication that the breakers are improperly specified or adjusted.
Will multiple tripping of a circuit breaker damage the circuit breaker?
You don't specify whether you mean low-voltage circuit breakers, such as MCBs (miniature circuit breakers) or high-voltage circuit breakers. In either case, repeated tripping under fault conditions causes arcing which damages the main contacts of the circuit breakers. For this reason, high-voltage circuit breakers are taken out of service after a specified number of tripping operations, so that the contacts can be maintained or, if necessary, replaced. MCB contacts are inaccessible, and the MCB may eventually require replacing.
How many ground fault interrupter GFCI circuit breakers are there in the circuit breaker panel of the secondary distribution center?
2
What are two methods used in most circuit breakers to protect electrical circuits?
There is a heated bimetallic strip that provides a time delay small overload protection. When its contact makes, it energizes a coil to trip the breaker. Some breakers are mechanical, though. There is a coil that trips the breaker instantly on large overload.
In what specific locations are arc-fault breakers not required to be installed?
Arc-fault breakers are not required to be installed in specific locations such as bathrooms, kitchens, garages, and unfinished basements.
Where are arc fault breakers required to be installed?
Arc fault breakers are required to be installed in bedrooms of residential buildings to help prevent electrical fires caused by arcing faults in the wiring.
Are arc fault breakers required for electrical safety in residential buildings?
Yes, arc fault breakers are required for electrical safety in residential buildings to help prevent electrical fires by detecting and interrupting dangerous electrical arcs.
Must arc fault breakers be used in a reconstruction project?
Yes, if you are replacing the service panel.
Is a fault?
An electrical fault is where the electrical current goes where it is not intended to go. Usually this is the quickest and shortest return path to the electrical supply service. An electrical fault will trip breakers and blow fuses in the circuit as protection to stop the short circuit.

How do you change one breaker on a 3 wire that feeds two regular circuit breakers to a single arc fault circuit breaker - or do you have to change both breakers to arc fault so each has a neutral?
In order to properly convert a circuit to an arc fault circuit breaker, both the hot and neutral wires must be connected to the arc fault breaker. This means that you would need to change both breakers to arc fault breakers, as each would require its own connection to the neutral wire to function effectively and meet safety standards.
What is open on fault?
There are isolation devices (Circuit breakers) meant to cut off or OPEN automatically when a fault occurs. The breaker has "opened" on fault.

The City of Tyler, TX approved ordinance 0-2008-141 on 11/11/2008. This ordinance requires arc-fault breakers in bedrooms.

What are the different types of Square D breakers available for residential electrical panels?
The different types of Square D breakers available for residential electrical panels include standard circuit breakers, tandem circuit breakers, and arc fault circuit interrupters (AFCIs).
