7.37 Checking Voltage at Receptacle
See Graphic: wc_gr002452
Electric shock hazard. Only qualified personnel should conduct this
test.
Complete this test with the machine running and both the main circuit
breaker and the receptacle circuit breaker in the “ON” position.
7.37.1 Using the AC voltage setting on the multimeter, test the receptacle for
120V±10% on 60Hz models; 230V±10% on 50Hz models.
7.37.2 If zero (0) Volts is measured, check the receptacle reset button if
equipped on your machine model. Depress the button if it has “popped
out”. If the reset button will not stay depressed, check the condition of
the wiring to the receptacle.
7.37.3 If the wiring is OK, test for voltage at the back of the receptacle. If
120V±10% on 60Hz machines or 230V±10% on 50Hz machines is
measured, replace the receptacle.
