6. When inserting duck bill probes into a test switch, short the CT secondary (+) first by
pulling the test switch in an open position. This will prevent possible arcing.
7. For clamp-on probes, clean contact surfaces and then snap and release the jaws to verify
a metal-to-metal contact of the jaws (dirt and grease may contaminate the surfaces).
8. For flexible probes, take care to pad mount CT installations. Always wear appropriate
PPE when inside the CT installation.
9. For pad mount CT installations, be wary of various items around the installation (chairs,
tables, etc.) which can potentially become a safety hazard.
