200 Amp Panel Upgrade in Novato: Common Questions

Specific answers to what Novato homeowners search for.

How do I know if I need a 200 amp panel?
A load calculation gives the real answer, but common triggers are frequent tripped breakers, a full panel, a 100 amp service with electric heating or cooking, or plans for an EV charger, heat pump, ADU or solar. We perform the calculation as part of the quote.

What is the difference between a 100 amp and a 200 amp panel?
The number is the maximum current the service can deliver to the house. A 200 amp service roughly doubles your available capacity, which lets you run more large loads at once without overloading the main breaker.

How much does a 200 amp panel upgrade cost in Novato?
In the Bay Area, a full service upgrade commonly runs from several thousand dollars to ten thousand or more depending on the meter, mast, wire runs and permit needs. Panel replacements without a service change cost less. We give a fixed written quote after an on-site assessment.

Do I need a permit for an electrical panel upgrade in Novato?
Yes. Panel and service upgrades require a permit and inspection through the City of Novato or Marin County, depending on your address. We pull the permit and schedule the inspection as part of the job.

How long does a panel upgrade take?
The on-site work usually takes about a day, with power off for much of it. Total timeline includes permitting and, when the service changes, scheduling with PG&E, so planned upgrades can take a few weeks while emergency replacements can be accelerated.

Will my power be off during the upgrade?
Yes, for part of the day while the old panel is removed and the new one is connected. We tell you the planned window in advance and can help you prepare refrigerators and sensitive equipment.

Is a Federal Pacific or Zinsco panel dangerous?
Both brands have documented problems with breakers that may fail to trip under fault conditions, which is why many electricians and insurers recommend replacement. If you have one, schedule an evaluation soon rather than waiting for a failure.

Will I need a new meter or service mast?
Often, if the service is being increased or the equipment is old, damaged or non-compliant. We assess this during the visit and include it in the quote, and we coordinate with PG&E on the utility-side requirements.

Can a panel upgrade help me add an EV charger or heat pump?
Yes, if your current panel cannot handle the extra load. In some cases a load management device or a subpanel can avoid a full upgrade, and we will tell you which option is cheaper and safe for your home.

Can you replace a burned or failing panel as an emergency?
Yes. If your panel is scorched, buzzing or failing, call us. We can make it safe, replace it on an expedited schedule and coordinate with the building department and PG&E to restore power as quickly as the process allows.
