Frenchelectrican, your comments about inspecting the old wiring brings to mind a common problem with service changes. After years of oversized fusing (using 30 amp fuses for #14 wire), after the service change is done the customer invariably overloads some circuits. I guess it would be good to inspect, and advise the customer about upgrading the circuitry first, so that the customer can know better about what the project will actually entail.
