Estimated Read Time: 11 minutes

Upgrading electrical service from 100 to 200 amps can solve nuisance breaker trips, power today’s appliances, and prepare your home for EV charging. In this guide, you will learn when a 200 amp upgrade makes sense, what the job includes, how permits and utility coordination work, and what to expect on installation day. Maintain a safe and reliable power source with professional electrical panel installations, upgrades, and repairs.

Do You Really Need 200 Amps?

A 200 amp service is the modern standard for many single-family homes that run multiple high-demand loads. If you have an electric range, electric dryer, hot tub, garage workshop, space heaters, or plan to add an EV charger or heat pump, 200 amps often prevents overloads and nuisance trips.

Look for these signs you have outgrown 100 amps:

1. Frequent breaker trips when kitchen and laundry run together.
2. Lights dimming when a large motor starts.
3. Not enough spaces for new circuits.
4. Warm breakers or a buzzing panel.

Right-sizing your service is about connected load, demand factors, and the home’s future. Electric vehicle charging, induction cooking, and finished basements add substantial demand. A licensed electrician can perform a load calculation to verify if 200 amps is appropriate and whether any subpanels are also needed.

What an Electrical Service Upgrade Includes

A true 100 to 200 amp upgrade is more than swapping a box. It is a coordinated project that brings your service entrance and grounding system up to current standards.

Typical scope:

1. New 200 amp meter socket and service mast or lateral connection per utility specs.
2. New 200 amp main breaker panel with adequate circuit spaces and labeling.
3. Correct service entrance conductors and bonding jumpers sized for 200 amps.
4. Grounding electrode system upgrades, including grounding to water pipe and ground rods where applicable.
5. Replacement of outdated or recalled equipment as needed.
6. Arc-fault and ground-fault protection where required in living areas, kitchens, baths, garages, and exterior locations.
7. Whole-home surge protection at the main panel for sensitive electronics.

Our surge protection systems integrate with your main distribution panel and automatically shut off power instantly when even the smallest surge is detected, protecting your valuable electronics and appliances.

Local Permits, Inspections, and Utility Coordination

In the Milwaukee and Waukesha area, your service upgrade requires permits, inspections, and coordination with the utility for disconnect and reconnect. Utilities schedule meter pulls and re-energizing after the city or county inspector signs off. Plan lead time for both building inspection and the utility window.

Local insight that saves time:

• Morning disconnects help ensure same-day sign-off and reconnection.
• Clear access to the meter location and panel area speeds the inspection.
• If your mast or exterior meter location must move, expect an updated utility site check.

Over the Moon handles permitting, inspection scheduling, and utility coordination for you. You get one point of contact and live updates on your installation window.

Step-by-Step: How Pros Upgrade 100 to 200 Amps

1. In-home assessment and load calculation. We verify existing panel condition, feeder size, grounding, and available working space, then confirm whether a direct swap or relocation is best.
2. Permit submission. We prepare code-compliant diagrams and specify equipment that meets current standards.
3. Utility coordination. We schedule a temporary disconnect on the installation day.
4. Safe shutdown and removal. On-site, we turn off power, remove the old panel, meter socket, and service conductors as required.
5. Install new service equipment. We mount the 200 amp panel, set the meter socket, upgrade conductors, and complete grounding and bonding.
6. Circuit transfer and labeling. We migrate existing branch circuits, correct any defects we find, and label everything clearly.
7. Add protective devices. Where required, we apply AFCI and GFCI protection and recommend a main-panel surge protector.
8. Inspection. The local inspector verifies code compliance.
9. Utility reconnection. The utility restores power once the job passes inspection.
10. Final walkthrough. We review panel labeling, warranty information, and any recommended future improvements.

This process keeps the outage window as short as possible. Most upgrades are completed in one working day once permits are approved.

How Long Does It Take and What Will Happen on Install Day?

Permitting typically takes a few days to a week depending on jurisdiction and volume. On installation day, expect a 6 to 10 hour window with power off for part of it. We protect floors, set up clean containment if drywall work is needed, and keep you informed at each milestone.

What you will notice:

• A tidy staging area near the panel.
• Clear, legible labeling on the new panel.
• No-worry cleanup. Our white-glove approach leaves your home as we found it.

If your panel needs relocation for clearance or code reasons, we will discuss wall repair steps in advance. Many relocations require minimal drywall patching.

What Does a 200 Amp Upgrade Cost?

Costs vary by home and utility requirements. Variables include mast height, service type, panel location, grounding upgrades, and AFCI or GFCI updates. Homes needing a panel relocation or extensive rewiring may invest more.

Typical cost drivers:

1. New meter socket and service conductors sized for 200 amps.
2. 200 amp main breaker panel with additional spaces.
3. Grounding electrode system upgrades.
4. Code updates to existing circuits where required.
5. Optional surge protector, EV-ready circuits, or subpanel for a workshop.

Ways to save without cutting corners:

• Use our Free Second Opinion on major electrical estimates to verify scope.
• Bundle surge protection or EV circuit work during the same visit.
• Enroll in our VIP Gold Star Plan for member discounts on service.

Smart Panels, EV Charging, and Future-Proof Options

If you are upgrading anyway, consider a smart panel that monitors loads and gives you app-based control. Smart panels offer enhanced control and energy management capabilities, making your Brookfield home more efficient and giving you greater insight into your energy usage. They are ideal when you plan to add an EV charger, heat pump, or a workshop with heavy tools.

Planning an EV charger? During the assessment we check panel space, amperage, and charging goals. Many homeowners choose a 50 amp, 240 volt circuit for Level 2 charging. A 200 amp service provides the headroom so you can charge the car and cook dinner without tripping breakers.

Add a whole-home surge protector at the same time. It is a cost-effective way to defend refrigerators, smart TVs, routers, and HVAC boards from voltage spikes.

Safety First: Why This Is Not a DIY Job

A service upgrade involves high fault current, utility coordination, and code-critical grounding. Mistakes can cause fires, shock hazards, or failed inspections that delay power reconnection. Only a licensed electrician should touch the service entrance, meter socket, and main bonding jumper.

We install and maintain circuit interrupters to protect against shock and fire hazards in kitchens, bathrooms, garages, and outdoors. When we upgrade your service, we verify that GFCI and AFCI protection is applied where required for added safety.

What Happens to Your Existing Wiring and Circuits?

Upgrading the service does not automatically replace branch-circuit wiring. During the panel transfer, we inspect breakers, conductor sizes, and terminations. If we find aluminum branch circuits or deteriorated insulation, we will provide options. Many Milwaukee-area homes benefit from adding dedicated appliance circuits for ranges, dryers, furnaces, and EVs.

Instead, dedicated appliance circuits are installed that use the minimum amount of wiring to power high power-load devices. Adding these circuits reduces nuisance trips and improves safety when you add new appliances or renovate.

Preventive Care After the Upgrade

A new panel is not a set-it-and-forget-it item. Thermal cycling, dust, and new loads can create issues over time. We recommend an annual visual check and tightening under power-off conditions by a pro at least every few years.

When a Panel Replacement Alone Is Not Enough

Sometimes the safest solution is a combined service and wiring update. Examples include panels with chronic overheating, water intrusion at the meter, or damaged service conductors. Homes with additions or finished attics may need a subpanel to keep circuits organized and accessible.

Our electricians handle complete or partial rewiring projects to improve safety, reliability, and energy efficiency. If you are using an older fuse box, we will gladly inspect or upgrade your existing system to a more modern setup.
