Troubleshooting a Tripped Outlet (Virtual Circuit Breaker)
After a Virtual Circuit Breaker is properly configured, any “trip” conditions
should be properly investigated before resetting the circuit breaker’s state.
Constantly toggling the relay state from Tripped to Off to On without first
clearing the condition that caused the trip causes the relay to trip again.
If the trip occurs at a high amperage, this can reduce the lifetime of
the relay.
CAUTION A qualified electrician should be called to investigate and resolve
tripped breakers. Failure to resolve the root cause of tripped breakers can
cause severe damage to equipment and other facilities.
To troubleshoot a tripped outlet (Virtual Circuit Breaker):
1. Identify the equipment plugged into the tripped outlet.
2. Are there any obvious problems with the equipment? Is the
cord frayed? Is there a burnt smell? Correct these issues with
the equipment.
3. Unplug the equipment and reset the Virtual Circuit Breaker.
4. If the Virtual Circuit Breaker resets okay, have the equipment checked
out by a qualified service technician. If the technician cannot identify
any issues with the equipment, contact Cyber Switching Technical
Support for additional assistance.
