l I.
Potential Problem During a Bechtel witnessed test of a General Electric Class IE Motor Control Center at Mebane, North Carolina, a test failure was documented on March 27, 1981, which was caused by a piece of "Varglas" wire tie material becoming lodged between N.O. contacts of Relay FX
]
(Points 7 and 8 on Drawing 221B5925). This prevented relay contacts from closing when the relay was energized.
A follow-up surveillance was completed for the related GE equipment delivered to the jobsite. This activity found that the "Varglas" wire ties were loose on wiring bundles and found in the bottom of the MCC panels. The following Nonconforma..ce Reports have been issued to identify these conditions as follows:
NCR MCC Tag Numbers E-J-1094 1E-PRA-M31 and 1E-PHB-M32 E-J-1095 2E-PHA-M31 and 2E-PHB-M32 E-A-106 2E-NHN-M20 (Non-Class IE)
I II.
Approach To and Status Of Proposed Resolution-Bechtel has contacted GE regarding these conditions, but has not yet received their evaluation and corrective action plan.
III.
Projected Completion of Corrective Action and Submittal of the Final Report Y
l The evaluation, resolution and Final Report are forecast to be completed by December 15, 1981.
