Fort Worth Electrical Panel & Service Upgrades — 100A to 200A

Estimated Read Time: 11 minutes

If you’re searching how to upgrade 100 amp to 200 amp service in North Texas, you likely need more capacity for today’s loads. This guide explains when a 200 amp upgrade makes sense, what it costs, and how the permit and utility process works in DFW. We’ll show you the safest path to pass inspection the first time, support EV charging or a new HVAC, and protect your home’s value.

Why Consider a 200 Amp Service Upgrade?

Most homes built decades ago were wired for 60–100 amps. Today’s homes power larger HVAC systems, EV chargers, smart appliances, and outdoor amenities. A 200 amp upgrade provides the headroom for comfort, safety, and future projects.

Key reasons to upgrade:

Frequent breaker trips when multiple appliances run.
Lights dim when the AC or microwave starts.
Adding an EV Level 2 charger, heat pump, or new kitchen suite.
Panel is out of code, corroded, or has mixed breakers.
Planning a generator, pool, spa, or home addition.

A larger service is not only about wattage. It is also about modern protection, clean distribution, and room for dedicated circuits so equipment runs as designed.

“Needed our central electrical panel replaced. The work was efficient, and thorough. We were very pleased.”

What’s Included in a 100 Amp to 200 Amp Upgrade

A true service upgrade covers more than just the panel. Expect a licensed electrician to evaluate the entire service path and bring the system to current standards.

Typical scope:

Load calculation to determine the required service size.
New 200 amp main breaker panel with clear circuit labeling.
Service entrance conductors resized to meet 200 amp ratings.
New meter base if required by the utility or city.
Grounding and bonding upgrades to meet today’s code.
Whole‑home surge protection at the service when required.
Exterior emergency disconnect where adopted by your city.
Permits, inspections, and utility coordination.

Milestone handles the full workflow, including utility coordination and final cutover so your power downtime is minimal.

Code and Safety: Facts That Protect Your Home

Code compliance is not optional. It is the backbone of a safe, insurable installation.

Two hard facts you should know:

The 2020 National Electrical Code requires a surge protective device at the service for dwelling units (NEC 230.67) in jurisdictions that have adopted it. Many North Texas cities enforce this, so your upgrade may include a listed SPD at the main panel.
The 2020 NEC also introduced an emergency disconnect requirement for one‑ and two‑family dwellings (NEC 230.85). In many DFW jurisdictions, that means a labeled, readily accessible disconnect on the exterior.

Material sizing matters:

Typical 200 amp services use 2/0 aluminum or 2 AWG copper service conductors per NEC 310.12, depending on installation method and temperature ratings.
Proper grounding electrodes and bonding jumpers reduce shock risk and must be verified during the upgrade.

Local insight: In the DFW area, utilities coordinate meter pulls and may require a new, rain‑tight meter base. Expect the city inspection before the meter is re‑installed and service is re‑energized.

Signs You’ve Outgrown 100 Amps

It is not always obvious that a home has outgrown a 100 amp service. Look for these patterns:

Breakers nuisance‑trip when you run the dryer and oven together.
AC startup causes lights to flicker or dim.
Rooms rely on power strips and extension cords because there are not enough circuits.
The panel is older than 15 years, shows rust or corrosion, or has double‑lugged neutrals.
You plan a project with heavy draws: EV Level 2 charging, heat pump conversion, induction range, workshop tools, pool equipment, or a standby generator.

When technicians inspect, they do not default to replacement. If safe repair can bring your system into compliance, they will recommend it. When corrosion, heat damage, or capacity limits prevent a safe result, replacement becomes the responsible option.

“Due to the storms... one of the circuits blew on our electric panel... The repair was perfect and Scott Clark was very knowledgeable and friendly.”

How a 200 Amp Service Supports EVs, HVAC, and Generators

EV charging: Level 2 chargers often require a 40–60 amp dedicated circuit. A 200 amp service gives you headroom to charge faster without compromising other loads.
HVAC upgrades: High‑efficiency heat pumps and modern air handlers can draw significant current at startup. Dedicated circuits with capacity prevent dimming and nuisance trips.
Standby generators: Whole‑home systems pair best with clean panel layouts, automatic transfer switches, and proper service sizing so essential and non‑essential loads are balanced.

Our team routinely installs automatic transfer switches for standby generators and performs the panel work required to make these systems seamless during outages.

“Two old blown breaker panels, replaced with code compliant main and sub panel, dedicated outside shutoff, whole house surge protector... in 8 hours? Yeah they did that.”

What Does a 200 Amp Upgrade Cost in North Texas?

Pricing depends on scope and site conditions. Typical factors include:

Panel and breaker type: Main panel vs. main‑lug with exterior disconnect.
Service entrance length and routing: Overhead vs. underground.
Meter base replacement and utility standards.
Grounding and bonding corrections.
Whole‑home surge protection and arc‑fault/GFCI requirements.
Permit fees and inspection scheduling.

Homeowners commonly invest more when the service is underground or when extensive grounding corrections are needed. You will receive transparent, itemized pricing up front. Advantage members enjoy discounted member pricing on services and repairs.

How Long Will It Take?

Most panel and service upgrades can be planned within a few days and completed in one working day once permits and utility schedules are in place. Power is typically off for several hours during the cutover. We stage materials in advance and coordinate the inspector and utility to minimize downtime.

Risks of DIY or Hiring the Lowest Bidder

Safety: Service equipment contains lethal voltages. Errors can cause arc flash, fire, or shock hazards.
Insurance and resale: Unpermitted work can void coverage and derail closings.
Performance: Undersized conductors, loose terminations, or missing surge protection cause nuisance trips and equipment failures.

“Logan... was diligent and quick to identify the problem and fixed it. He also pointed out the upgrade to our box we need to consider... He inspires trust.”

Repair vs. Replace: When a Full Upgrade Is the Right Move

Sometimes a strategic repair extends panel life. Other times, replacement is the only safe option.

Consider replacement when:

The panel or bus bars show corrosion or heat damage.
Breaker brands are mixed or obsolete.
There is no remaining capacity for required dedicated circuits.
You plan a project that will exceed your service rating.

Consider repair when:

A single faulty breaker can be replaced with a listed match.
A neutral or ground termination needs correction.
Minor labeling and AFCI/GFCI updates resolve compliance issues.

We will show you both paths with pricing so you can decide with confidence.

Planning Your Upgrade: A Simple Checklist

List current high‑demand loads and future projects (EV, pool, heat pump).
Schedule a professional load calc and panel evaluation.
Confirm local code adoption for surge protection and emergency disconnect.
Decide on optional add‑ons like generator‑ready or EV‑ready circuits.
Pick your installation day and plan for 4–8 hours of power downtime.

Frequently Asked Questions

Do I really need 200 amps, or can I add just one more circuit?

A load calculation answers this. If your existing service is near capacity or you plan EV, HVAC, or a remodel, 200 amps prevents repeating costs and nuisance trips.

How long does a 100 to 200 amp upgrade take?

Most upgrades finish in one day once permits and utility scheduling are set. Expect several hours of planned power downtime during cutover.

Will my utility or city need to be involved?

Yes. We pull the permit, meet the inspector, and coordinate with the utility for meter removal and reinstallation after approval.

Do I need whole‑home surge protection with a new panel?

Many DFW cities that adopted the 2020 NEC require an SPD at the service. It protects electronics and sensitive HVAC boards from surges.

Can I add an EV charger without upgrading the service?

Sometimes. If the load calc shows available capacity, we add a dedicated circuit. If not, a 200 amp upgrade supports faster, safer charging.
