7-6. Cable Checks

The procedure outlined in a through d below is given as a convenient method of checking for continuity or shorts in single

conductor and multiconductor cables.

a. Disconnect both ends of the cable to be tested.

b. Check for grounds using a multimeter to check continuity between each lead and the conduit or each lead and

its respective shield. Continuity should indicate infinity.

c. Check for opens by selecting one conductor in the cable and grounding it at one end to the conduit. At the other

end of the cable check continuity between lead and conduit. Infinite indication is an open circuit.

d. Follow the procedure in step c for the remaining

conductors in the cable.
