[QUOTE="Rob., post: 448485, member: 27131"] You can even point him in the direction of this thread. It was something that used to be done, but with modern overload protection devices the tolerances are as such that 100% is what you set it at. Even a star delta starter when set at 0.58%FLC is still protecting the motor at it's 100%FLC due to where it is installed in the circuit. I know there are some situations where you would set an OL device higher than 100% now, but they're only in specialist situations and wouldn't be an answer in an exam like the one shown, without a hell of a lot more information in the question.
