Both black wires appeared to be hot when I tested them. Then I noticed the two red wires. This was an unused junction box in the ceiling of my garage. I have two two outlet receptacles. Only one of the black wires should be hot right?




White is cold.

green (if present is ground)

all other colors are hot such as black , red, blue & yellow

Replace your "is" and "are" with "should be".

We really don't know how the OP's box is wired.

P.S. The term is "nuetral" not "cold".
