Mystery junction box??

A friend who is remodeling a old house ran into a junction box in the attic. This box had the screws on top painted "Red" and the box was also painted red. What does this mean. Is it a constant hot or what. Thank You, Joe

It could mean anything.

Try to see where the wires come from and/or go to; use a meter to determine the circuit and what they are for.

Probably not applicable here ,but in commercial wiring ,we always (and exclusively) use red junctions for the fire alarm systems. As I said, probably not applicable in a house.

Looks like you may have to trace this one out.

In the house where I grew up, back in MA, we had an oil burning furncace int he basement. There was a switch at the top of the stairs which turned off the oil pump. The switchplate was always red.

I'm guessing that it was simply painted red for decoration purposes sometime in the past. Junction boxes are not color coded in residential wiring. Red boxes and conduits are often part of a fire protection system in a commercial building.
