Yes, but the word has (I would say confusingly) been used in that specific sense by regulations - a sense with which most members of the general public will not be familiar."Competent" was/is not the right word to have used because (lately) it has been the only requirement for an 'electrician' to be sent out into the world to work in other people's houses, where they should not need to ask how it's done.
