Dpne that... their route is known



Does that mean that there appears to be a direct run
from the breaker to the first outlet and that while you
have voltage at the wire end at the breaker there is no
voltage at the wire end at the first outlet? How much of
that wire can you see? If for example it runs through a
basement and then goes straight up where the outlet would
be, then I'd be fairly confident that's how it runs.
If you can't really follow it, then my first suspicion
would still be that there is another junction in a box
somewhere that's the problem. Could be in the basement,
attic, etc. And have you used a non-contact type circuit
tester to see if there is voltage on it as far as you can follow
it?

Do you have easy access to just run a new cable, eg through
basement, and then up? If so, and you can't find a break,
then that is likely the easiest solution.







Then, as trader suggested, I'd look



for bad backstabs. Then I'd look for bad junction boxes.




Done that



I'd also use a standard $5 plug-in outlet tester on the circuit while


energized to see if there's an open neutral or hot.




Done that





As a last resort I'd suspect that the circuit breaker has failed and might swap it out to test it




Swapped it out & replaced it with a new one





I do find it odd that one breaker is powering only one outlet That's


fairly uncommon in my experience.




There are two double outlets on the breaker
