Gould, Inc., Electrical Products Group, reported to the NRC on September 11,
1979 potential defects in certain NEMA size 3, Starters and Contractors. A 
possible binding or seizure of the carrier assembly, within the support 
plate of the stationary contact assembly, is caused by an undersized 
dimension of the support legs. 

Starters and contractors with date code 7822 to 7935, model and serial 
numbers A1O, A11, A12, A13, A14, A20, A21, A22, and P1O are involved. Faulty
units were manufactured and distributed between June 1, 1978 and August 30, 
1979. The attached listing of nuclear plants, which have received some of 
this motor control equipment, represents a preliminary check of shipment 
records. This listing, however, may not be complete. 

Gould, Inc., will recall uninstalled items for retrofit and has retrofit 
kits available for field installation. 

Based on the above, licensees are advised to verify all motor starter and 
contractor shipments received from Gould, Inc., between June 1, 1978 and 
August 30, 1979, and assure that applicable model and serial number 
components are corrected by retrofit and subsequent electrical operation 

No written response to this Circular is required. 

If you desire additional information regarding this matter, contact the 
Director of the appropriate NRC Regional Office.
