I performed an inspection yesterday on a early 1980s home and found overheating of the main service conductors in the main breaker panel due to no antioxidant paste to the aluminum conductors. As you can see, the left terminal has oxidized and caused enough resistance to cause it to get very hot and melt the insulation. Of course I stressed heavily in the report to my customer to have this repaired, but also felt I needed to let the seller's agent know also so she could notify the current owners of it's condition for their safety and in case the sale didn't go through. She returned my call today and acted like I was being an alarmist because she had always viewed the antioxidant paste issue as something that is a nit picky item that we chose to throw in our reports. I emailed her the photo and I think she now understands the importance of this paste.
