Subcommittee Scope

Welcome to the home page for the CRE Subcommittee on Electrical Equipment (SOEE). The mission of the SOEE is to develop standards and recommended practices specific to the refining industry including:

  • RP 500 Electrical Area Classification
  • Std. 541 Form Wound Induction Motors and
  • API 540 Electrical Installations in Petrochemical Facilities.

The SOEE also works closely with other standards developing organizations​​, such as the Institute of Electrical and Electronics Engineers (IEEE) and the National Fire Protection Association (NFPA), and provides​​ technical comments to NFPA 70 National Electrical Code (NEC). The subcommittee analyzes technical issues, provides training and advice on relevant technical issues, and shares information, which is useful to the industry as a group.

This site provides information on upcoming meetings, minutes and presentations from recent meeting, and information on the status and balloting of standards maintained by the SOEE.
