The lighting panel was inspected and found to be contaminated with plaster inside of the enclosure. This is consistent with production work. When this work was done the electrical current carrying components are masked off. However, front cover was removed and each circuit breaker also disconnected and individually inspected for burnished or plaster contamination - other defects. The circuit breakers were opened and closed several times to insure proper operations and found in good working order.
