ECN Forum Forums General Topics of the Trade General Discussion Area Elevator tripping AFI

Wonder if anybody else has run into this problem?
I have a cutler hammer ch panel, when the elevator goes up or down the afi trips(keep in mind this afi has nothing to do with elevator). I talked to cutler hammer and the engineer says that the freq. drive motor is putting noise on the line and when 3 amps are present on the circuit, that noise will trip the circuit (I know this is true because when all lights in sewing room and office are off...no problems)anyway Cutler Hammer says to filter the motor to eliminate the problem. The elevator guy is trying to say he's never had this problem before and of course doesn't want to pay for the filter and labor, his solution is to put in a siemans breaker(yea right). Have any of you guys had problems with residential elevators tripping AFI's? Any thoughts about responsibility for additional $$ cost's appreciated too.
