FAQs
Why would I need an electric panel upgrade in Monterey?
Many homes in Monterey were built before today’s high-demand appliances—such as electric vehicle (EV) chargers, heat-pump HVAC systems, induction ranges, and rooftop solar inverters—were common. Older 60–100 amp panels simply lack the capacity and safety features to supply these loads. Upgrading to a modern 200 amp (or larger) service increases available amperage, adds more breaker spaces, and incorporates the latest arc-fault and ground-fault protection, reducing the risk of overloaded circuits, nuisance tripping, and electrical fires.
What size service panel is recommended and how is the proper amperage calculated?
For most single-family residences, a 200 amp main service panel accommodates current and planned loads, including EV charging, future battery storage, and all-electric appliances. Our licensed electricians perform a NEC Article 220 load calculation, adding up all fixed appliances, general lighting, small-appliance circuits, and demand factors to verify the correct size. In larger homes or properties with multiple EVs or extensive solar/battery systems, a 225 amp, 320 amp, or even a 400 amp service may be advised.
How does an upgraded panel support solar, batteries, and EV charging?
Modern load centers feature higher bus ratings, larger service conductors, and spaces for back-fed breakers or dedicated sub-feed lugs that connect PV inverters, battery storage systems, and Level 2/Level 3 EV chargers safely. They also integrate smart breaker technology that enables load-shedding, real-time monitoring, and utility-approved rapid-shutdown for solar arrays—capabilities older fuse boxes and split-bus panels lack.
Are permits and utility coordination required in Monterey County?
Yes. Any main service upgrade in Monterey County requires an electrical permit from the local building department (Monterey, Pacific Grove, Seaside, Carmel, etc.) and a scheduled inspection. Because the utility (PG&E) owns the meter and service drop, we also submit a ‘Service Upgrade Notification’ to PG&E. They will disconnect power on the day of work and reconnect after the city/county inspector approves the new installation, ensuring compliance with the California Electrical Code and PG&E Greenbook standards.
How long will the upgrade take and will my power be shut off?
A typical residential panel swap takes one full workday once permits are in hand. Power is usually disconnected for 4–8 hours while the old panel is removed, new conductors are terminated, grounding/bonding is verified, and the new panel is inspected. We provide temporary power solutions for critical loads (refrigerators, medical equipment) if needed, and schedule the PG&E disconnect/reconnect in advance to minimize downtime.
What does an electric panel upgrade cost in the Monterey area and are incentives available?
Costs vary with amperage, wiring complexity, trenching (if relocating the service), and whether the meter/main combo is changed. In Monterey County, most 200 amp upgrades range from $3,000–$5,500, while 400 amp services can reach $7,000–$10,000. Homeowners converting to all-electric systems may qualify for federal 25C tax credits (30 % up to $600 for panel upgrades tied to heat-pump or EV projects) and local Monterey Bay Community Power electrification rebates. We offer financing and help customers file the necessary documentation to capture every available incentive.
