My report/quote states: "Zinsco/FPE have many known safety issues that can readily be found by researching them on the Internet. Because of these known problems, we recommend replacement of these panels. In addition, many insurance companies realize that electrical panel replacement is a standard component of home maintenance, and will offer a discount for doing so." (About the only panel I don't feel the need to replace is Square D QO. These panels and breakers seldom have any issues, and I'm happy to relay that customers) I then post the the notice attached from State Farm.
I verbally tell customers that I will not make additions (add circuits) to Zinsco/FPE panels because of what I feel is the liability involved.
I also charge $150 for inspection and report/quote. I get the money on arrival, they get the report within 24hrs. If they use me to replace the service, I will credit the $150 toward the final invoice.
