FAQs
Why should I upgrade my electric panel in Monterey?
Many homes and businesses in Monterey still rely on panels installed 30–40 years ago. Modern appliances, EV chargers, solar arrays, and home automation systems require more amperage and extra breaker space than older panels can safely supply. Upgrading eliminates chronic tripping, prevents overheating that can lead to fires, and brings your electrical system in line with today’s National Electrical Code (NEC) and California Title 24 efficiency standards.
How do I know my existing panel is undersized or obsolete?
Warning signs include frequently tripped breakers, flickering lights when large appliances start, warm or buzzing breakers, a panel rated at 60–100 amps, or the presence of brands such as Zinsco or Federal Pacific that have documented safety issues. A licensed Monterey electrician can perform a load calculation and infrared thermal scan to confirm if the panel is overloaded or contains degraded components.
What size panel upgrade do most Monterey properties need?
Single-family residences typically move from a 100 amp panel to 200 amps to support EV charging and future solar battery storage. Larger homes with multiple HVAC systems or secondary units may require 300–400 amps. Commercial sites often upgrade to 480/277 volt 3-phase gear with 800–1,200 amps. Your electrician will calculate demand and future growth to recommend the correct main breaker rating and bus bar capacity.
How long does an electric panel upgrade take from start to finish?
Our precision engineering process usually spans 2–4 weeks. Step 1: Site assessment and load calculation (1–2 hours). Step 2: Engineering drawings and permit application with Monterey County Building Services or the City of Monterey (3–7 business days). Step 3: Utility coordination with PG&E for service shut-off and reconnection scheduling (5–10 days). Step 4: On-site panel replacement, grounding, and labeling (one full workday). Step 5: Inspection and power restoration (same day if scheduled early).
Will the upgrade affect my solar or EV charging system?
Yes—in a good way. A new 200 amp or larger panel provides dedicated breaker space and proper bus sizing for rooftop solar backfeed, battery storage inverters, and Level 2 or Level 3 EV chargers. During design, we verify that the new panel’s bus rating plus solar contribution does not exceed the 120% NEC rule, ensuring PG&E approval and safe bi-directional power flow. We can also install a Generation Meter Adapter if required by your Net Energy Metering (NEM) agreement.
What is the typical cost of a panel upgrade in the Monterey area?
For a standard residential 200 amp upgrade, expect $3,500–$5,500, which includes permitting, materials, labor, and PG&E coordination. Complex projects—such as relocating the panel, trenching for a new service conduit, or adding whole-house surge protection—can range from $6,000–$9,500. Commercial 3-phase gear starts around $12,000.
