    UL vs UR motors

    Hello all, What's your understanding about UL vs UR motors ? I believe UL motors are tested by UL and went through extensive test. UR, on the other hand, is "recognized", not tested. And some motors don't get UL tested and labeled because they are "general purpose" motor types. Regards, Stan

    Hi all, Is there any regulation or requirement to test the protection circuits on a regular basis, say every 6 months for HPA or welding cabinets...? Thanks, Stan
