A. If the upper ECAM DU gives the warning message C/B TRIPPED REAR PNL N-R:
- do a check of the status of the circuit breakers on the rows N thru R.
(1) If all the circuit breakers are closed:
- do a check for the grounded circuit breaker
- replace the grounded circuit breaker.
(2) If one circuit breaker or more are open: NOTE : On ground you must not close a tripped circuit breaker without
____ trouble shooting of the related system.
(a) Do an isolation check of the wiring between the C/B and the related system.
