Upgrading electrical service from 100 to 200 amps is one of the safest ways to add capacity for modern living. If your breakers trip, lights dim with the AC, or you are planning an EV charger or remodel, a 200‑amp panel can solve the strain. In this guide, we explain how to upgrade electrical service from 100 to 200 amps safely, what permits and inspections look like in the Sacramento area, and how our licensed team delivers clean, code‑compliant results in as little as one day.

Why Upgrade From 100 Amps To 200 Amps

Older homes with 100‑amp service were built before today’s power needs. Central air, induction cooking, tankless water heaters, hot tubs, and Level 2 EV chargers all push a 100‑amp service to its limit.

Common signs you are due for an upgrade:

Frequent breaker trips or warm breakers.
Dimming lights when large appliances start.
Not enough spaces for new circuits.
Plans for EV charging, solar, or an addition.

A 200‑amp service increases available capacity and future‑proofs your home. Most modern homes require 200 amps after a proper load calculation. Our team evaluates existing loads and future plans so the panel size fits your life now and later.

Safety, Permits, and Inspections: How It Really Works

Electrical service upgrades must be permitted and inspected. In the Sacramento region, the local Authority Having Jurisdiction issues the permit, and your utility, such as SMUD or PG&E, coordinates the service drop or lateral. We handle both for you.

What we manage for you:

Permit application and utility coordination.
Code‑compliant installation and labeling.
Utility disconnect/reconnect scheduling.
Final inspection and approval.

Two hard facts you can trust:

We are BBB Accredited A+ Rated and fully licensed and insured in California (CA CSLB #635556).
Most panel installations are completed in one day, and 93% of repairs are completed on the spot when needed.

What Is Included In A 200‑Amp Upgrade

A complete 200‑amp service upgrade typically includes:

New main service panel rated for 200A with proper labeling and AFCI/GFCI breakers where required.
New service entrance conductors and meter main or meter socket as required by the utility.
Bonding and grounding upgrades, including grounding electrodes and bonding jumpers.
Load calculation and panel schedule updates.
Replacement of aging breakers, lugs, or damaged feeders.
Whole‑home surge protection at the panel for first‑line defense against spikes.

Because every home is different, our electrician inspects the mast, weatherhead, meter location, clearances, and working space to finalize scope before work begins.

Step‑By‑Step: How We Upgrade 100A To 200A Safely

Evaluation and load calculation. We confirm your existing loads, future EV or remodel plans, and code requirements.
Proposal with clear pricing. You receive a transparent scope and options for surge protection, generator readiness, or sub‑panels.
Permits and scheduling. We file permits and set your target upgrade date around your calendar.
Utility coordination. We schedule the service disconnect/reconnect with SMUD or PG&E and stage materials ahead of time.
Installation day. We replace the panel, upgrade grounding and bonding, label circuits, and install surge protection.
Testing and cleanup. Breakers are torqued to spec, connections verified, and the workspace is left clean.
Inspection and power‑on. We meet the inspector, close the permit, and confirm everything operates as expected.

Most upgrades finish in one day, with power restored the same afternoon or evening. If weather or utility scheduling affects the plan, we keep you informed at every step.

Costs, Timelines, and What Drives Price

Every home is unique, but these items often influence total cost:

Panel type and brand selection.
Meter location changes or service relocation.
Length and size of feeders and service conductors.
Grounding and bonding upgrades needed for code.
Add‑ons like whole‑home surge protection or a generator interlock/transfer switch.

We provide clear upfront pricing before any work begins, with financing options that can make a new panel as low as an affordable monthly payment subject to approval. Ask about our limited‑time offer for new circuit breaker and panel installs.

Code Compliance Without The Jargon

Homeowners should not need to memorize code articles. Here is what matters in plain terms:

Working space and clearances must be maintained in front of the panel.
Breaker sizes must match wire sizes and the appliance load.
GFCI and AFCI protection is required in many locations.
Panels must be properly grounded and bonded.
Labels must be accurate and legible.

Our team delivers clean, code‑compliant work and handles permits and inspections so you can feel confident on inspection day.

EV Chargers, Solar, and Backup Power: Plan It Once

Upgrading to 200 amps is the right time to plan for EVs, solar, and generators.

EV charging. Level 2 chargers need a dedicated 240V circuit. We confirm capacity, add the circuit, or upgrade the panel so you can charge at home without tripping breakers.
Solar readiness. We review busbar and breaker positions for solar backfeed according to the 120 percent rule or alternate methods approved by your AHJ.
Backup power. If you are considering a portable or standby generator, we can install an interlock or transfer switch during the panel upgrade for a safer, cleaner solution.

A future‑proof plan costs less than opening the panel multiple times later.

Whole‑Home Surge Protection While We Are There

The best place to stop damaging voltage spikes is at the panel. Our licensed electricians connect protection directly at your panel to create a strong first line of defense for your entire electrical system. Many devices install quickly, often in under an hour, and can extend the life of sensitive electronics.

How To Choose The Right Electrician For A Service Upgrade

Use this fast checklist before you hire:

Licensing and insurance. Verify the California contractor license and coverage.
Permit and inspection handling. The contractor should pull permits and meet the inspector.
Utility coordination. Experience with SMUD or PG&E matters for smooth scheduling.
Clear upfront pricing. No surprises, and options explained in writing.
Technicians you trust. Background‑checked, drug‑tested, and continuously trained.
Real guarantees. Look for a satisfaction guarantee and strong parts and labor coverage.
Local experience. Sacramento homes have quirks like panel clearances in tight garages and meter location rules. Hire a team that knows neighborhood conditions.

AAA Electrical Services checks all seven boxes and has served Sacramento area homeowners for over 30 years.

What To Expect On Installation Day

Arrival and safety setup. We protect floors and work areas, verify the plan, and review the day’s timeline.
Power‑off window. Utility shuts power off during the changeover. We advise you on fridge and device prep.
Panel swap and upgrades. The old panel comes out, new panel and grounding go in, circuits are labeled, and surge protection is installed.
Testing. We torque to spec, test GFCI/AFCI where present, and verify circuits.
Inspection and energizing. We meet the inspector, address any notes, and coordinate the utility to turn power back on.

After we finish, you receive a summary of work, photos if requested, and recommendations for any future improvements.

DIY vs Professional: Why This Is Not A Weekend Project

Working on service equipment is dangerous and can void insurance if done without permits. Even with the main breaker off, parts of a panel and service conductors can remain energized. Improper grounding, loose lugs, or misapplied breakers can cause fire or shock risk.

Our advice is straightforward:

Do not attempt a 200‑amp upgrade without a licensed electrician.
Always pull permits and schedule inspections.
Choose a contractor who coordinates with the utility and documents the work.

We complete these upgrades cleanly and legally so you can sleep well at night.

Common Myths About 200‑Amp Upgrades

Myth: “A bigger panel will increase my energy bill.” Reality: Usage drives your bill. Capacity prevents overloads but does not add usage on its own.
Myth: “I can just add tandem breakers to make space.” Reality: Tandems are only allowed where the panel is listed for them. Overstuffing can be unsafe and non‑compliant.
Myth: “Only new homes need 200 amps.” Reality: Many older Sacramento homes benefit when adding AC, EV, or electric appliances.

Sacramento‑Area Insight You Can Use

We work in Sacramento, Elk Grove, Roseville, Folsom, Citrus Heights, Rancho Cordova, Rocklin, Davis, Carmichael, and Woodland. Each city may follow the California Electrical Code with local amendments. Utilities like SMUD and PG&E have specific meter and service requirements. We know these rules, pull the right permits, and schedule inspections so your upgrade passes the first time.

Add‑On Options Worth Considering During Your Upgrade

Sub‑panel for a workshop or ADU to separate circuits neatly.
Dedicated 240V circuits for EV charging, sauna, or welder.
Whole‑home surge protection to protect electronics.
Arc‑fault and ground‑fault protection as required and recommended for safety.
Generator interlock or transfer switch for outage readiness.

Bundling these with a panel project keeps costs down and avoids extra service visits later.

Maintenance After The Upgrade

Electrical systems benefit from periodic checks. Our VIP+ Maintenance Plan includes priority scheduling, 24/7 emergency coverage, twice‑yearly 20‑point maintenance, switch and receptacle inspections, a discounted diagnostic fee, preferred client pricing up to 10% off repairs, and new system discounts including 5% off electrical panel upgrades. VIP+ members also enjoy a “Fixed Forever” Guarantee that doubles the manufacturer’s warranty on repairs.

When You Need Repairs Instead Of A Full Upgrade

Sometimes you do not need a new panel. If diagnostics reveal a single damaged breaker, a loose neutral, or aging components that can be safely repaired, we complete targeted, code‑compliant repairs the same day in most cases. If your panel is unsafe or undersized, we will show you why a replacement is the better choice and provide side‑by‑side options so you can decide with confidence.

Clear Next Steps

Schedule a load evaluation and safety check.
Review your upgrade options and pricing.
Pick an install date that works for your family.

We take it from there, manage permits and inspection, and return your power the same day in most cases.
