I’m in the process of refinishing my basement, and I’ve installed the breakers. My panel uses Square D QO breakers that have a window that shows red when the breaker is in the tripped position. Breakers are then reset by turning fully off and then on.

One of the new breakers shows just a tiny bit of red in the window when it’s in the “on” position. It doesn’t instantly trip when turned on. It does this even with the breaker removed from the panel. The breaker switch moves fully to both on and off positions.

Is this something to be concerned about?
