Customer wants me to hookup a runtime meter for his large shop equipment for him to schedule maintenance on the equipment, Mfg has maintenance at set periods. I'm not familiar with retrofitting such a device. Equipment in question is a 240V single phase 5hp motor with only 2 ungrounded conductor and a ground and doesn't have from factory any meter. Question is, the run meter that they have has no instructions, no identifiers other than a + and - near the spade terminal, would I be correct in that I really have no way from the markings to know 1. AC or DC, 2. Max voltage, 3. Amperage limitation, 4. No UL listing stamp, and just a made in China stamp (not necessarily relevant just side bar, another Amazon special) that I should advise that unit may be or is not usable for this application and what code reference could be used to substantiate such a claim? (If any) ps they were not able to get me any usable spec sheets for unit from the Amazon site.
