I always recommend they be replaced. Had one Wednesday and the agent called me and said that there was nothing wrong with the panel. I just replied, I would not live in that house for fear of it burning down and am surprised it has not burned by now. Then I referred her to the web site. Her reply was if the deal goes south we will call you to inspect the next house. Some people just don't think home inspectors know what we are talking about, you have to draw them a picture.
