A couple of related issues. My old pump is old brass Premier driven by a 1.5 Magnetek Centurion motor wired for 230v. I know it's at least 18 years old, but suspect it is the original equipment installed at the time of pool construction some 30 years ago. I bought a new Hayward Superpump (SP2605X7, just 3/4 horse since I've taken the heater and the spa off-line). New pump is set up for 230v. The problem is the pump instructions say that it must be permanently grounded to the green wire from the electrical service. Problem is, there is No such wire....just two hots (black) and nothing else. Wiring diagram on the old pump is still readable and clearly shows only the 2 hot connections to L1 and L2 and no ground. Taking the black-plate off the old motor confirms that there is no grounding screw. So I wired the new pump up per instructions and pulled a 12 awg green wire through the conduit, but don't know where to ground it. I fired up the pump for the first (and only) time and it only ran for about 2 seconds then shut off. I checked the breakers at the panel and it didn't appear that they had tripped since they had a full-range of motion when I pushed them from ON to OFF. That's where it sits right now....don't want to burn up a new pump, nor shock anyone. If the old pump was not able to be grounded, is that requirement for the new pump because of updated electrical codes? Is there a way to ground the pump motor without a wire going back to the panel? And finally, can the new pump shutting down be related to its lack of grounding, or maybe did I screw up when connecting it?
