Afcis look like normal circuit breakers and fit into electrical panels in the same manner but they are able to detect dangerous electrical currents that may produce arcs.

Arc formation in circuit breaker.

In air blast circuit breaker or in breaker where a gas flow is present between the electrical contacts the heat loss of arc plasma occurs due to convection process. A combination arc fault circuit breaker is not equivalent to a dual function circuit breaker. Generation of arc in circuit breaker. What is circuit breaker.

Afcis are designed to sense an arc which is an electrical leak caused when a hot wire touches a neutral or ground but doesn t trigger the circuit breaker. It can make or break circuit either manually or by remote control. As long as this arc is sustained in between the contacts the current through the circuit breaker will not be interrupted finally as because the arc is itself a conductive path of electricity. Circuit breaker is switch capable of making or breaking the circuit under no load as well as on load condition.

An arc fault circuit interrupter afci also known as an arc fault detection device afdd is a circuit breaker that breaks the circuit when it detects an electric arc in the circuit it protects to prevent electrical fires. Beginning in 2002 the national electrical code required that all new construction include arc fault circuit interrupters on branch circuits inside electrical panels. They do not protect against arcing conditions that produce erratic and often reduced current. Read more circuit breaker and arc phenomenon.

During this if the circuit breaker opens its contacts then the contact area reduces which increases current density electron density further it increases the. A circuit breaker in conjunction with relay can break the circuit under fault condition. With ever changing electrical code requirements a circuit breaker with the ability to provide both arc fault protection as well as ground fault gfci protection was long overdue. It is not intended to identify bad arcs on circuits in the home.

You may also like to read basic principle. Although current sensing circuitry enables afcis to detect arcing conditions unintended trickles of current may also cause the breaker to shut off afcis are very sensitive. Heat loss from an arc in circuit breaker is takes place through conduction convection as well as radiation. In circuit breaker with plain break arc in oil arc in chutes or narrow slots nearly all the heat loss due to conduction.

An afci selectively distinguishes between a harmless arc incidental to normal operation of switches plugs and brushed motors and a potentially dangerous arc that can. But beware the combination function that is identified on recently. When a short circuit current of usually 10 times greater than the normal circuit flows through the circuit breaker under fault condition.
