## Discrepancy

UPON REPLACEMENT/ UPGRADE OF A CIRCUIT BREAKER IN THE CABIN SERVICES CIRCUIT BREAKER PANEL, IN THE RT RADIO RACK AT FS 110, A 20 GA WIRE WAS FOUND PINCHED AND HAD PREVIOUSLY SHORTED TO THE FACE PLATE LEAVING A SCORCH MARK ABOUT THE SIZE OF A DIME.  THE WIRE WAS SUBSEQUENTLY REPAIRED, PROPERLY STOWED AND UNIT APPROVED FOR RETURN TO SERVICE.  REF GAC DWG NR LC41 390035-01 - L MAIN UNSEITCHED WIRE NR 1XX102D12 FROM TB1.  SUGGEST TECH TAKE EXTRA CARE IN THE RE-MOUNTING OF THIS SERVICE PANEL TO AVOID CATCHING WIRES ON THE AFT SUPPORT BRACKETS. (K)
