I was replacing all fluorescent light fixtures with pot lights and when i removed a fixture, there were 2 14/2 cables connecting with the light.
I thought one was the power coming in, and the other was the power going out to another fixture.
Turns out that when I separate them, cap them off, and turned on the breaker, both had power after I tested with a NCVT (both are from the same breaker source).
Now I am confused as it means that both 14/2 are for power coming in? For the time being (I'll put in a junction box), I finished the job by keeping the two cables connected as it was initially, but i am not sure I understand why they were both hot when i separated them.
