Proposed recommended practices for medium-voltage motor controllers for rubber and plastics industries

THE RUBBER and Plastics Subcommittee of the General Industry Applications Committee is presenting for discussion the following proposed Recommended Practices, in the hope that comments from the wide circulation so provided will be helpful in attaining maximum usefulness from the specifications. Membership of the Working Group assigned to this project consists of engineers from both large and small rubber companies, electrical manufacturers, machinery builders, and consulting engineering firms. The requirements listed are a composite of the desires of the persons who apply controls to the large rubber and plastics processing machines, influenced to an appropriate degree by the manufacturers. Discussions resulting from this presentation are necessary to assure the widest possible acceptance of the proposal.
