How hard do you think it is to trace from one outlet to the next, along
a wall? It's not foolproof but it's very doable. And once again, if it's
for safety, it's just a joke because I'll guarantee you, no fireman is
going to wonder around looking for junction boxes. So we come right back
to what I said originally, it's a feelgood reg for convenience ONLY!


I suppose with a powerful magnet I could find a metal junction box if it
were close to the surface, but how would I know it was the right box?

How would I locate a hidden junction box with just a multitester? How
much damage would I do if I cut my way to it? How could I be sure the
hidden box I found wasn't live?
