Start with the active system
First determine which old circuits still serve the home. Replacement decisions should be based on the actual system rather than visible remnants alone.
Consider the next project
A renovation or weatherization project may change what is practical or required because walls are being opened or insulation is being added.
Plan the endpoint
Replacement is easier to evaluate when you know what the finished electrical system needs to support: lighting, receptacles, appliances, renovated spaces, or broader modernization.
