I just finished installing my new 1.5 HP Whisperflo Pump (one speed 230V). My old pump pump was a 2HP Mustang (230v). I connected electrical with ground going to ground, one hot to Line 1 and the other to Line 2. I fired up the pump and after about 3 or 4 seconds of the pump trying to prime it trips the 20 amp breaker. Suspect of my connections I reconnected and made sure they were tight, fired up the pump again only to have it trip the breaker again. I pulled the connections off one more time and pulled out my voltage meter and both line 1 and line 2 measure 120 v. I don't understand as the old pump was running fine with the same electrical circuit and runs at a higher amperage rating then the whisperflo.
One thing I don't understand is the factory has a white wired connection on one of the Line 2 poles that connects somewhere into the motor. does this white wire stay connected? Of course Pentair seems to have no trouble shooting information anywhere that I can find for electrical issues.
Has anyone else experienced a similar problem with the Whisperflo? I can't believe I may have to call for pool service because of a tripping breaker!
Any help is greatly appreciated!!
