Is equipment available for testing after wiring is installed so that contractors can demonstrate that their work has been competently completed?
...we are not aware of special equipment available for such testing. If wiring is installed competently, there should be no reason for any testing that is not done for a circuit without an AFCI. However, there are two possible practices that can be used to test the installation, if a test is desired:
<OL TYPE=A>
[*]Probably the best test is to install an AFCI, at least temporarily, in the circuit. For this test to be efeective, the circuit must be complete, since it must be energized as in service with 120 volts. First, use the test button to verify that the AFCI is functioning properly. Then leave the AFCI in the energized circuit for some period of time. If it does not trip, that is an indication that the circuit is acceptable.
