'Kate Megahertz' mentioned on another thread that QO breakers have seen some bus contact failures.
The photo is from a Schneider web page, but they give no other details.
Anyone have a link or personal experience about how prevalent this is ?
Did Sq D switch to aluminum busses recently or sometime in the past that would initiate problems ?
