Heating Element Amperage - Six Wire Elements
The table below shows the approximate amp draw through each loop (see page 17) of a six
wire heating element. First determine the actual rated wattage and voltage of the element
being tested - see page 23. Then follow the Heating Element Amperage Test procedure on
page 25 to measure amperage through each loop of the six wire heating element being
tested. The 3 amp readings, one for each loop, should be approximately the same. Compare
the measured values to the values in the table below. Keep in mind there may be some
variance between measured values and the values in this table due to fluctuations in
voltage, temperature and the calibration of test instruments being used.
Heating Element Amperage - Three Wire (Y Configured) Elements
The table below shows the approximate amp draw through each wire (see page 17) of a
three wire heating element. First determine the actual rated wattage and voltage of the
element being tested - see page 23. Then follow the Heating Element Amperage test
procedure on page 25 to measure amperage through each wire of the three wire heating
element being tested. The 3 amp readings should be approximately the same. Compare the
measured values to the values in the table below. Keep in mind there may be some variance
between measured values and the values in this table due to fluctuations in voltage,
temperature and the calibration of test instruments being used.
