Last night when I was working on the panel I was putting in a few more breakers, and noticed a problem that I had before. Some of the breakers are really really hard to get in. So hard that I could not get a couple in, I stopped as I was afraid of damaging the bus.
I had this happen before and I returned the breakers in question.
Does this happen normally when out of a full panel you find a couple that just don't want to go in?
Should I try to open up the contacts on the breaker somehow and try again or should I treat these as manufacture defects?
All breakers & the panel were purchased via authorized retail outlets, Menards, Home Depot, or Lowes.
Should I try to open up the contacts on the breaker somehow
Whatever you do, don't do this. I would keep the breakers and write to CH, they would probably be interested in them for QA purposes, and would likely send you free replacements in exchange for you mailing them the bad ones.
