rirj John G. Davis January 2,1973 Limitorque Division of Philadelphia Gear was notified by mail requesting that corrective action be taken as soon as possible and that Florida Power Corporation be notified of the action to be taken and the time required to complete the action. Limitorque has requested that we supply them with a tabulation of the units involved so that they can supply re-placement torque switches which will be installed on-site upon receipt.

This replacement program may take from several months up to a year, depending upon availacility of replacement units.
