Additional Short Circuit Current Ratings
Square D I-Line plug-on lugs installed in this I-Line Combo switchboard
and protected by indicated Square D circuit breakers are suitable for use
where the available short circuit current is not greater than that shown in
the following table. The short circuit current rating cannot exceed the
rating marked on the protecting circuit breaker. The protecting circuit
breakers may be the main or, if plugged onto the same I-Line bus stack,
may be downstream from the plug-on lugs.
