Dear Mr. Seyfrit:
In response to IE Bulletin 79-28, we offer the following:
1.
Our Architect-Engineer has determined that 14 EA-180 NAMC0 switches will require replacement of the top cover gasket.
2.
None of these switches have been put in service or exposed to ambient temperatures of more than 1750 F.
3.
The replacement gaskets are being ordered from NAMC0 and will be installed by June 30, 1980.
Should you have any other questions, please advise.
Very truly yours,
