overcurrent, and ground faults. Ensure that the protective devices are properly rated and comply with national
and local codes.
Caution
If the system loses power or both TNC, TNCE, TSC, TNCS-2, TNCS-2O, or TSCE cards are reset and the
system is not provisioned to get the time from a Network Time Protocol/Simple Network Time Protocol

If you are using the TNC, TNCE, TSC, TNCS-2, TNCS-2O, or TSCE cards, the system clock will run for up
to three hours. In this case, no action would be required.
