Basics - 28,000 gal in-ground pool. 1 HP motor rated at 6.6A at 220V and 13.6 A at 110V. Built in 1989. Owned house last 5 years. Problem - after I had the pool opened two weeks ago, everything ran fine. 2 days later had problem with circuit breaker blowing. I've isolated that problem to an underground wire issue. However, in the trouble shooting of that problem, I have learned that my motor is drawing higher than rated current. On the 220 circuit, it draws 7.8-7.9 A. On a 110 circuit it is drawing 14.7-14.8A. There are no air leaks in my system, the filter in the main housing is clean, skimmer baskets clean. The motor was new last year, and as part of my circuit breaker problem, thought the motor was the culprit, had it replaced under warranty. Both motors pulled ~8 Amps on the 220 circuit. I am trying to figure out what might be causing the motor to pull such high current. On the 220 circuit it runs cool, on the 110 circuit its warm. Century motor.
