Condition
Possible Cause
Countermeasure
Voltmeter Indicates
Normal Voltage But
no Output Voltage is
Delivered.
Measure the
voltage at the
output terminal
using a voltmeter.
(250V at AC range)
Output voltage is
0 V.
Circuit breaker is
OFF
Set the circuit
breaker to ON. If
it goes OFF again,
check the cause
(overload, short
circuit, etc.).
Set the circuit
breaker to ON
after removing the
cause.
