Grounded Element Test – Amperage Method - using “clamp type” Amperage

Meter. Many multimeters could be used to conduct this test but be certain that the amperage

limits of the multimeter will not be exceeded.

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

Test Conditions

Wires on the water heater are all connected to their proper terminals.

Power to the heater is "on".

Both thermostats are satisfied.

Clamp the jaws of the Amp Meter around each wire connected to the elements –

one wire at a time.

If …

… then

meter reads the proper amperage (+5, -

10%)

the thermostat is calling for heat.

meter reads approximately 1/2 of the

proper amperage

replace the element.

meter reads NO amperage thermostat and element are not grounded.
