5.12 Cable Test Procedure
The purpose of the Cable Test is to quickly
check the test leads and breaker contacts for
continuity at each of the 3 phase contacts.
(For example, a close test should begin with
all contacts open; conversely an open test
should begin with all three contacts closed—
the closed condition also checks continuity
of the test leads for opens or erroneous
hookups.) When the test hookup is made to
the breaker, run a Cable Test to make sure
all 3 test lead clips are properly connected
(contact clips are across mating contacts).
Begin with the Start-Up Menu (below):
