#61-183 Alligator Clip Adapter
This adapter allows the SureTest to analyze non-outlet based circuits for branch circuit
safety and performance. Simply plug the alligator clip adapter into the IEC connection on
the front of the SureTest. Then, properly connect the hot (black), neutral (white) and ground
(green) alligator clips onto the circuit. Correct test results are dependent on making good
connections with the alligator clips onto the circuit.
WARNING:
The SureTest is designed for 120/240VAC circuits only. Do not
exceed the rating of the SureTest with this adapter.
This adapter also allows the operator to use the SureTest (#61-165 only) to verify AFCI
protection on non-outlet based circuits in bedrooms, such as on circuits used for lighting,
ceiling fans, and smoke detectors.
#61-175 Ground Continuity Adapter
This adapter allows the operator to verify that a cabinet or equipment chassis has been
properly bonded to the system ground. Plugging the SureTest into the ground continuity
adapter isolates the SureTest from the electrical ground. If the equipment is properly
grounded, then connecting the alligator clip from the ground continuity adapter to the cabi-
net or equipment chassis should provide a pathway to ground, and consequently a normal
wiring condition on the SureTest.
After the ground continuity adapter has been connected, the SureTest can be used to mea-
sure the ground impedance of the cabinet or equipment chassis back to the panel. See the
section on Line Impedance Measurements for test instructions for ground impedance.
This adapter can also be used to test GFCI receptacles on 2-wire circuits. Connect the alligator
clip on the adapter to a ground, such as a metal water or gas pipe prior to testing the GFCI.
#61-176 Isolated Ground Adapter
This adapter allows the operator to verify that a receptacle is completely isolated from the
system ground that is bonded to other devices on the branch circuit. Test the ground
impedance of the receptacle and record the ohms value. (See the section on Line
Impedance Testing for details on obtaining the ground impedance value). Remove the
SureTest and plug it into the isolated ground adapter. Attach the alligator clip to the center
receptacle screw or metal junction box, and re-insert the SureTest into the receptacle and
record the ohms value.
The isolated ground adapter creates a parallel pathway to ground, which results in a lower
ground impedance reading with the adapter versus with the receptacle with the isolated
ground. If the two readings are the same, then the receptacle does not have an isolated
ground. If the reading taken with the isolated ground adapter is lower, then the receptacle
has an isolated ground.
Maintenance
