Rule Summary: The Commission adopted emergency updates and now permanent amendments to the rule addressing Residential Pool Pump and Motor Combinations. The amendments focus on updating the Commission rules to add permanent magnet synchronous motors (PMSM) to the list of permissible motors to be sold in the state. The amendments update rule language requiring residential pool pump and motor combinations as well as replacement residential pool pump motors sold or offered for sale in California to be certified by the California Energy Commission and appear in the Commission’s Modernized Appliance Efficiency Database.
Previously, the Appliance Efficiency Standards allowed the certification of five types of motor construction: Permanent Split Capacitor (PSC), Capacitor Start-Capacitor Run, Electrically Commutated Motor (ECM), Capacitor Start- Induction Run, or Split Phase. Permanent magnet synchronous motors (PMSM) were not a permissible motor construction type listed in the regulation and could not be sold or offered for sale in California until the emergency rule went into effect.
Status: Notice of the final approved emergency rule was published in the April 7 California Register. The rule went into effect March 27. Staff has since worked on a permanent rule for publication and that rule was submitted for approval. The Office of Administrative Law (OAL) approved the rule and notice of the final adopted rule was published in the California Register. The permanent rule went into effect on October 5, 2017.
