Meg ohm readings

WebWhat is a good Meg reading on a motor? Contents show. If the megger reads a resistance under 1 (1,000 ohms) on your meter after the initial 60-second interval, the cable has failed and the cable should be removed. If the megger reads a resistance between 1-1.25 on your meter, then the cable passes. Any reading above 1.25 is considered excellent. http://www.graycoolingman.com/uploads/1/0/6/6/10667336/copeland_4-1294.pdf
