I'm looking for a descriptive, elegant English term or phrase for fausse manoeuvre, which is when a technical operator (a human) performs a "bad" operation or sequence of actions.
For example, "The electrician performed a fausse manoeuvre when he rewired the machine, leading to a short circuit."
I am leaning towards "maloperation", but that often describes an automatic component malfunctioning rather than human error. What would be the best English term?
