I was helping a neighbor, when I accidentally found 2 independent power feeds to a single double wide box. One circuit from each of 2 circuit breakers! My neighbor thanked me for pointing this out as he was only turning off one breaker.

Now here is the interesting point, as far as I know the building codes and electrical codes state ONE CIRCUIT PER BOX, and this is what I was always told. When I looked carefully at the wiring this all appears to be ORIGINAL (2013 vintage) wiring as all of the wiring had the same paint overspray.

IMHO, this is a dangerous situation, so in case the codes have changed, check ALL of the wiring when working in any box. I have a handy non contact tester that I bought at Lowes and this is what tipped me off to the second circuit.
