Both the circuit breaker and receptacle are installed similar to the GFCI circuit breakers and receptacles that are present in many homes already. The circuit breaker method protects the entire circuit, while the receptacle protects only from the point of installation on the circuit, to the end of the circuit. A caveat for the receptacle method is that it is only considered meeting the code requirements if the portion of the circuit between the electrical panel and the AFCI receptacle is installed in pipe or armored cable and all boxes in the circuit must be metal the common practice of using plastic fiber boxes or romex cables would prohibit this solution.

The hot and neutral circuit wires will all connect directly to the AFCI circuit breaker, and protects the entire circuit from arc faults. Use AFCI receptacles to provide protection to the circuit only from the point at which the receptacle is installed. Replace the first non GFCI receptacle in the circuit with the AFCI receptacle and connect the wires from the panel to the LINE terminals and the wires that continue to the rest of the circuit to the LOAD terminals. Depending on wiring methods used during construction, this method may not satisfy the requirements of the code. The AFCI receptacles were much more popular prior to 2.
