any sparkies in the house? I noticed some yellow arcing where a breaker was contacting the hot side buss bar which usually indicates a poor connection. this panel is in my shop & is mostly empty. I moved the breaker to a lower position & it there was no connection. I hit the buss bar & the breaker with a wire wheel & sprayed them both with electrical contact cleaner. I moved the breaker to another part of the buss bar & it is now working fine. I checked the lower part of the buss bar where I had no connection with a meter & it had proper voltage. any ideas why i'm not getting contact on that part of the buss bar???
