How do you add amperage to existing 100 amp service without calling smud and county?

To increase the amperage of your existing 100 amp service without involving SMUD or the county, you could consider upgrading your electrical panel to a higher amperage rating, such as 200 amps, and replacing any old wiring that may not support the increased load. However, it's crucial to ensure that your home's electrical system can handle this upgrade safely. Keep in mind that any significant electrical work typically requires permits and inspections for safety and code compliance, so it's advisable to consult a licensed electrician for guidance.
