[Al (astral highway)]

Just to note, I’m not a lawyer, but I do have some insight into this. I wonder that there has ever been a prosecution for the discovery of an as the OP calls it, illegal fitting, against a consumer. What could happen is that in the event of a third party being harmed or fatally electrocuted, a prosecution could be begun to attempt to probe liability and causation. So it’s not to trivialise the question , just to clarify the circumstances under which it could be become catastrophically serious.
