No.
Test Item Procedure Criteria
1 Withstand
voltage of
the main
ground after
L1, L2, L3,
and N are
short-
circuited
1. Short-circuit L1, L2, L3, and
N.
2. Select the withstand
voltage test function for
the tester. Connect one
end to the short-circuit
point of the phase wire
and the other end to the
main ground point. Set the
dielectric withstand
voltage to 2121 V DC, rise
time to 10s, and hold time
to 60s.
● The leakage current
during the test is less
than 10 mA.
● No breakdown or
ashover occurs
during the test.
