I'm about to rewire my pool pump to 240v, and just for S&G I threw an amp meter on the hotwire within my breaker panel and it said the motor was pulling 24-25 amps at 120v when it should be only a max of 18.6!. Its a 1.5 hp motor. I know voltage drops with distance, are amps inversely related? or is something else going on? Its about a 100' run from the panel to the pump. Any help would be appreciated.
