If you have an older home with an original electric service panel and breakers, it is a good idea to have an electrician use a thermal
camera or heat sensor on it. By turning all the circuits on the electrician can use these tools to see if you have hot spots on the breakers, wire, and buss bar. This will allow to replace them now before the electrical panel is damaged. Replacing the electrical breaker now will save you thousands later replacing the whole panel.
