Close Test Tabulation
This discussion presents results for a Close test, with explanations of the
origination of important results. The Breaker Report is shown in
Figure A.131.
A The auxiliary switch monitored by the AUX contact
triggers the timing of the Main Contacts, which
happens to be 15.3 ms after test initiation
(Figure A.133 on page A-113). This is useful when
timing specifications are based on close coil
energization rather than test initiation.
