9. Reconnect the inlet with the fuse replaced to power, if it was disconnected
in Step 4.
10. (Optional) You can perform manual transfer back to that inlet, if preferred.
See
Manual Transfer (on page 112).
Overcurrent Protectors for Outlets
PX3TS models rated over 20A (North American) or 16A (international) contain
overcurrent protectors for outlets, which are usually branch circuit breakers.
These circuit breakers automatically trip (disconnect power) when the current
flowing through the circuit breaker exceeds its rating.
If the circuit breaker switches off power, the front panel display shows:
•
CbE
, which means "circuit breaker error." See Overcurrent Protector
Information (on page 130).
At the same time, the internal beeper turns on. See Beeper (on page 168).
When a circuit breaker trips, power flow ceases to all outlets connected to it.
You must manually reset the circuit breaker so that affected outlets can
resume normal operation.
Comparison: Fuses for the inlet transfer switch protect the inlet transfer switch
from overload. Overcurrent protectors for outlets, if available, protect
associated outlets from overload. The rating of a fuse for the inlet transfer
switch is higher than the rating of an overcurrent protector for outlets. See
Fuses for the Inlet Transfer Switch (on page 164).
Resetting the Button-Type Circuit Breaker
Your button-type circuit breakers may look slightly different from the images
shown in this section, but the reset procedure remains the same.
To reset the button-type breakers:
1. Locate the breaker whose ON button is up, indicating that the breaker has
tripped.
2. Examine your PX3TS and the connected equipment to remove or resolve
the cause that results in the overload or short circuit.
This step is required,
or you cannot proceed with the next step.
