Marietta GA Electrical Panel & Service Upgrades — 100A to 200A

Estimated Read Time: 12 minutes

Thinking about a 200 amp service upgrade? If your lights dim when appliances start, breakers trip often, or you are adding an EV charger or heat pump, upgrading from 100 amp to 200 amp service can solve overloads and future-proof your home. In this guide, you will learn the signs you need more capacity, the exact steps of the upgrade, how permits and inspections work, realistic costs, and ways to save with local incentives and our current offers.

Do You Really Need a 200 Amp Service?

A 200 amp service increases available electrical capacity so your home can safely power modern loads. It is often the right move when you add high-demand equipment or notice persistent power issues.

Common signs you need more capacity:

1. Frequent breaker trips, warm breakers, or burning odors near the panel.
2. Lights dim when the HVAC, oven, or dryer starts.
3. You use multiple power strips to reach limited circuits.
4. You plan to add an EV charger, heat pump, tankless water heater, finished basement, or home addition.
5. Your panel is full and cannot accept new breakers or has outdated components.

Key benefits of upgrading:

1. More circuits for dedicated loads like EV chargers and kitchen appliances.
2. Lower risk of nuisance trips and overheated wiring.
3. Improved home value and easier resale for buyers planning future upgrades.
4. Compatibility with smart panels and renewable energy integrations.

Local insight: Many Atlanta homes built before the 1990s still run on 60 to 100 amps. That was fine before central AC, high-efficiency heat pumps, and EVs became common. If your service size has not changed since move-in, a professional load calculation will likely reveal your true capacity needs.

What Upgrading From 100A to 200A Involves

A safe upgrade is a coordinated project with your electrician and the utility. Here is the typical flow our team follows:

1. In-home assessment and load calculation. We evaluate your current panel, main service, grounding and bonding, and planned loads. We also check for heat damage, double taps, and recalled or unsafe equipment.
2. Proposal and options. You receive a clear scope for a 200A main panel or load center, possible sub-panel, surge protection, and smart panel options.
3. Permitting. We pull permits with your local authority. In Metro Atlanta, an inspection is required after the work is complete.
4. Utility coordination. If a meter base or service mast upgrade is needed, we schedule with the utility for a safe disconnect and reconnect.
5. Installation day. We replace the panel, upgrade service entrance conductors as needed, correct grounding and bonding, add new breakers, label circuits, and test.
6. Final inspection and utility restore. We meet the inspector, complete any punch list, and get power restored.
7. Homeowner walk-through. We show you the panel layout, warranties, and maintenance tips.

Pro tip: Ask your electrician to plan spare capacity for the next 10 to 20 years. A few extra spaces today can save the cost of a sub-panel later.

Safety and Code Essentials Homeowners Should Know

Your upgrade must meet current safety standards. A few important facts that guide our work:

1. Working clearance in front of the panel must be at least 36 inches deep and at least 30 inches wide, with clear headroom. Keeping this space open allows safe maintenance and inspections.
2. Grounding and bonding must be correct at the service equipment. We verify grounding electrode conductors and connections to approved electrodes.
3. Arc fault and ground fault protection are required in many living and wet areas. These smart breakers reduce fire and shock risk.
4. Service disconnects must be readily accessible. We verify location and labeling for quick shutoff in an emergency.
5. Surge protection is now a widely recommended layer of protection. A whole-home surge protector helps defend appliances and electronics from voltage spikes.

These code driven details are not window dressing. They prevent shock, arc flash, and equipment damage. During your consultation we will point out any clearance issues, outdated bonding, or missing protection and outline the fix.

Timeline and What to Expect on Install Day

Most upgrades are completed in one day once the permit is issued and the utility window is scheduled.

Typical timeline:

1. Consultation and load calculation: same day or next day.
2. Permit approval: usually a few business days depending on the city.
3. Installation day: 6 to 10 hours on average, including labeling and testing.
4. Final inspection: typically within 24 to 72 hours after install.

What installation day looks like:

1. We cover floors and protect nearby surfaces.
2. Power is turned off for several hours during the panel swap and service upgrades.
3. We replace the panel, breakers, main conductors as needed, and correct grounding and bonding.
4. We install a whole-home surge protector if included, then label circuits in plain language.
5. We restore power, test GFCI and AFCI devices, and verify major appliances and HVAC run correctly.
6. You receive a walkthrough, your warranty information, and tips to register any applicable incentives.

Cost Factors and Smart Ways to Save

Every home is different, but the total price reflects these elements:

1. Panel type and brand. Standard 200A panels are cost effective. Smart panels add load management, remote control, and energy insights.
2. Service entrance upgrades. New meter base or service mast can add cost if required by the utility.
3. Length of service conductors and grounding upgrades.
4. Number of new circuits and specialty breakers like AFCI and GFCI.
5. Permit and inspection fees by jurisdiction.

Ways to save today:

1. Tax credits. The Energy Efficient Home Improvement tax credit can offer up to 600 dollars for qualifying panel upgrades that support eligible equipment like heat pumps. We help you document eligibility.
2. Active offers. We currently advertise 150 dollars off residential electrical panel upgrades and a free in-home consultation for replacements or upgrades.
3. Financing. Spread payments for minor fixes to major upgrades with approved credit.
4. Bundle protection. Add a whole-home surge protector. We install these for a flat price and it protects your new panel and electronics.

Hard facts you can use:

1. Bardi offers 20-year warranties on new electrical panels installed by our team.
2. Our 89 dollar Whole-Home Electrical Safety Inspection covers the panel, exposed wiring, smoke alarm testing, and more. Our whole-home surge protector install is 449 dollars.

200A vs Smart Panels and Future Proofing

A standard 200A panel increases capacity. A smart panel does that and adds control and insights.

Smart panel advantages:

1. Real time energy monitoring at the circuit level.
2. Automated load management that sheds or delays non critical loads to prevent nuisance trips.
3. Remote circuit control from your phone for travel or rentals.
4. Seamless integration with solar and battery storage so you can choose which circuits stay powered.

If you plan to add solar, storage, an EV, or electrify appliances in stages, a smart panel can reduce future labor by handling load management in software rather than expensive rewiring later. Ask our team to model both options during your consultation.

EV Charger, Heat Pump, and Generator Readiness

Upgrading to 200A is often step one for modern electrification. Here is how it supports popular projects:

1. EV chargers. We confirm panel capacity, pull permits, install a dedicated circuit, and complete final inspection. If the existing panel is full or undersized, we plan the 200A upgrade first so charging is reliable.
2. Heat pumps and high efficiency HVAC. These add continuous loads. We right size breakers, wire gauge, and disconnects so you meet manufacturer specs and code.
3. Standby generators. We plan transfer switches and protected circuits with your new panel to keep critical loads running during outages.
4. Kitchen and laundry remodels. Dedicated circuits for induction ranges, convection ovens, microwaves, and dryers prevent nuisance trips and overheating.

Bottom line. A 200A service provides the breathing room to add these systems without overloading the home.

Choosing the Right Contractor for a 200A Upgrade

The cheapest bid can be expensive if it misses safety or utility requirements. Use this checklist to compare:

1. Licensing and insurance. Ask for proof and the permit plan in writing.
2. Load calculation. Insist on a documented calculation, not just a guess based on age of home.
3. Utility coordination. Confirm who schedules the disconnect and reconnect and how long the outage will be.
4. Grounding and bonding corrections. These must be included, not quoted as surprises on install day.
5. Surge protection. Request a whole-home device to protect your new equipment.
6. Warranties. Look for at least a 10 year panel warranty. Bardi provides up to 20 years on new panels.
7. Reputation and response time. Bardi has thousands of 5 star reviews, same day service, and 24 or 7 emergency response when you need it most.

Local insight: Our Atlanta based teams know city permit reviewers and utility processes, which keeps projects moving and reduces delays.

Maintenance After Your Upgrade

A new panel is not set and forget. Keep it safe and reliable with simple steps:

1. Annual safety check. Our 89 dollar Whole-Home Electrical Safety Inspection includes a multi point panel check, smoke alarm testing, and surge review.
2. Keep clearance. Maintain 36 inches in front of the panel and do not store items there.
3. Test GFCI and AFCI devices twice a year using the test buttons.
4. Label updates. If you add circuits, ask us to update your panel directory so first responders and service pros can act fast.
5. Add surge protection. If not included at install, schedule a 449 dollar whole-home surge protector to protect HVAC, appliances, and electronics.

If you notice warm breakers, buzzing, or a burning smell, call for service right away. Bardi provides 24 or 7 emergency response across Metro Atlanta and surrounding cities.
