Troubleshoot for microwave tripping circuit as well as oven not working. Oven appliance cord connections in oven burnt up. Tested and inspected oven outlet and everything looked good. Recommended leaving unplugged and get new oven. Then I tested the microwave circuit my megging, testing continuity, voltage and visually inspected outlet and everything looked good. Plugged in and ran multiple other appliances with no issue. Recommended getting a new microwave. Then we swapped out the microwave circuit breaker for a duel function breaker to gfci protect it since it is in the kitchen, demoed basement outlets, installed whole home surge protection and corrected and oversized breaker and wrong branded breaker as a courtesy.
