Electrical Panel Upgrades for Palo Alto Properties
Palo Alto panel planning needs to account for both the existing electrical system and the building. In Crescent Park, Old Palo Alto and Professorville, check the panel, wiring and previous renovations before deciding what to replace. In an Eichler in Greenmeadow or Charleston Meadows, open-beam ceilings and limited concealed access may affect a new circuit route. The service rating and a load calculation determine whether planned EV charging, a heat pump or induction cooking need added capacity. A 200-amp upgrade is one possible outcome; a smaller charging load or suitable load management may also be worth evaluating.
Palo Alto has its own electric utility, City of Palo Alto Utilities (CPAU). Service changes therefore need coordination with CPAU as well as the city permit process. For a property in Professorville, check whether a proposed meter location or exterior conduit affects historic review. For an Eichler, confirm a practical circuit route before finalizing the scope. These checks help establish the work needed at the address.
Electrical project resources for Palo Alto
Palo Alto Utilities publishes its own electric service requirements for new and remodeled properties and warns that standards used by other utilities may not be accepted. A panel or charging design should therefore be checked against Palo Alto's current utility requirements and the city's matching permit checklist. Do not carry a PG&E-based service detail into a Palo Alto project without verification.
Choose the city checklist matching the charger, service replacement, or larger panel project.

Palo Alto FAQ
Does a Palo Alto panel upgrade go through PG&E or the city utility?
City of Palo Alto Utilities (CPAU) handles electric utility coordination in Palo Alto. A panel project may also need an electrical permit through city Development Services. Confirm the service work, inspection and reconnect sequence for the proposed scope.
Can you upgrade the panel on an Eichler without damaging the post-and-beam ceilings?
Circuit routing depends on the individual Eichler and its renovations. Open-beam ceilings and limited concealed space can make exterior conduit or another accessible route worth considering. Confirm the route and any finish repairs before authorizing work; damage-free installation cannot be promised from the house style alone.
My Palo Alto home still has a 100-amp panel and an EV on the way. Do I need 200 amps?
Not necessarily. A load calculation and an assessment of the existing panel establish whether the planned charger fits. A lower charging setting or suitable load management may avoid a service upgrade. Include any planned heat pump or induction range in that assessment.
Will an old Crescent Park or Professorville home need rewiring along with the panel?
Inspect the existing wiring before deciding. An older Crescent Park or Professorville home may have original sections, later alterations or a complete rewire. A panel change does not automatically require replacing every circuit, and it does not correct an unrelated wiring defect.
How long is my power off for a panel upgrade in Palo Alto?
The outage window depends on the approved work, CPAU scheduling and the required city inspections. Confirm the disconnect and reconnect arrangements before the installation date and plan for the possibility of delays. A single day without power cannot be guaranteed.
Can a like-for-like panel replacement in Palo Alto skip the CPAU application?
No. CPAU rules say only its own crews may pull or set a meter, and the Utility Service Application (form dated February 14, 2026) asks for the existing and requested main switch size even when the answer is No Change. It goes in with the building permit so the disconnect can be scheduled once engineering signs off.
Why does CPAU care about the AIC rating of my new panel?
Because the available fault current depends on the meter location and the length of CPAU's service cable. CPAU's standard minimum interrupting rating is 10,000 amps for panels of 200 amps or less and 27,300 amps above 200 amps, and the utility must be told if the meter moves, since that can change the required rating.

Can a 100-Amp Panel Handle an EV Charger?
A 100-amp label is a starting fact. Demand, equipment condition, circuit space, and charging needs determine the installation.
