Grounded Element Check – Amperage Method

Grounded Element Test – using “clamp type” Amperage Meter. Many multimeters could be used to conduct this test but be certain that possible amperage will not exceed the multimeter’s limit.

Complaint:A grounded element is suspected whenever the water temperature becomes excessively hot and/or the end user must push the high limit reset to reactivate the heater.

Amperage measures the flow of current through a wire.

Watts divided by volts = Amps

Conditions:

Power on

Thermostat is satisfied

59T4000
