Justin, TX Electrical Panel & Service Upgrades Guide

Estimated Read Time: 10 minutes

Upgrading from 100 amp to 200 amp service solves nuisance trips, supports EV chargers, and prepares your home for modern loads. If lights dim when appliances start or your panel is warm, a 100 amp to 200 amp service upgrade can restore safety and headroom. In this guide, you will learn clear signs you need it, how the process works in DFW, what it costs, and smart add‑ons like whole‑home surge protection. We also explain permits, utility coordination, and how to choose a licensed electrician you can trust.

Why Upgrade From 100 Amp To 200 Amp Service

Many older homes in DFW still run on 100 amp panels designed for a different era. Today’s homes power high‑efficiency HVAC, double ovens, EV chargers, hot tubs, and home offices. A 200 amp panel increases available capacity, reduces breaker trips, and creates space for future circuits.

Benefits you feel right away:

1. Fewer nuisance trips when multiple appliances run.
2. Capacity for Level 2 EV charging and future remodels.
3. Cooler, safer panel operation under heavier loads.
4. Improved home value and marketability.

Your home’s electrical system must match your lifestyle. A 100 amp to 200 amp service upgrade gives you room to grow without riding the edge of overload.

Clear Signs You Need a 200 Amp Upgrade

You do not need guesswork. Watch for these triggers:

1. Frequent breaker trips or a main that runs hot to the touch.
2. Lights dim when AC, dryer, or microwave starts.
3. Limited open spaces in the panel or tandem breakers everywhere.
4. Adding a Level 2 EV charger, hot tub, or new HVAC.
5. Aluminum feeders on a very old service or a rusted meter base.
6. You still have a fuse box or obsolete equipment.

If any apply, schedule a load calculation. Berkeys performs detailed load calculations to confirm the right panel size before work begins.

What a 100 Amp to 200 Amp Service Upgrade Includes

A proper upgrade is more than swapping a box. Our scope typically includes:

1. New 200 amp panel with matching main breaker.
2. Service mast, meter base, or riser updates where needed.
3. Proper grounding and bonding for safety and code compliance.
4. Whole‑home surge protection at the panel, if selected.
5. New breakers that match the panel and current code.
6. Labeling, testing, and balancing after installation.

Fact you can count on: the upgrade process takes 4 to 8 hours depending on home size. We shut off power at the meter, remove the old panel, and install a new one with proper grounding and surge protection. When complete, your system is tested, balanced, and ready for Texas heat.

Step‑By‑Step: How the Upgrade Works in DFW

Here is our proven workflow for North Texas homes:

1. On‑site assessment and load calculation to confirm 200 amp sizing.
2. Permit application with your city. We handle it end to end.
3. Schedule the cutover window. We coordinate with Oncor when necessary.
4. Power is shut off at the meter during the upgrade window.
5. Remove the old panel and install the new 200 amp panel and grounding.
6. Install new breakers matched to the panel and your circuits.
7. Optional add‑ons installed, like whole‑home surge protection.
8. Label, test, and balance loads for even performance.
9. City inspection and utility reconnection per local rules.

Expect clear communication, a tidy workspace, and a walkthrough before we leave.

Permits, Code, and Inspections in North Texas

Electrical service upgrades are permitted work. Your city will inspect the new panel, grounding, bonding, working clearances, and labeling. Local requirements in Fort Worth, Plano, and Arlington align with current National Electrical Code and city amendments. Our licensed electricians follow those standards and meet with inspectors so you do not have to. Where utility involvement is required, we coordinate with Oncor to minimize downtime.

Cost Factors and Financing

Every home is different, so pricing varies. Key cost drivers include:

1. Panel brand, capacity, and number of new breakers.
2. Condition of the meter base, riser, or service conductors.
3. Grounding upgrades, surge protection, and AFCI or GFCI needs.
4. Permitting, inspection fees, and utility coordination.
5. Add‑ons like EV charger circuits or generator transfer switches.

Financing is available with approved credit. We provide upfront options after your evaluation so you can choose the right package with no surprises.

Safety First: Why This Is Not a DIY Project

Working inside a service panel carries serious risk. Incorrect grounding, bonding, or conductor sizing can create fire and shock hazards. Utilities and cities require licensed electricians for service upgrades. Our team performs the work to code, and we pass inspection the first time in the vast majority of cases. Keep your family and home safe by using a licensed, insured professional.

Smart Add‑Ons to Pair With a 200 Amp Upgrade

A service upgrade is the best time to add capacity‑boosting and protection features:

1. Whole‑home surge protection: Installed at the panel in about 2 hours. It protects every circuit, not just what is plugged into a strip.
2. Level 2 EV charger circuit: Most installations finish in 4 to 6 hours depending on wire run.
3. GFCI or AFCI protection as required by current code.
4. Dedicated appliance circuits for ovens, dryers, or workshops.
5. Generator transfer switch and backup generator tie‑in. Whole‑home generator installs typically take 1 to 2 days and include the transfer switch, pad, and gas connection. They turn on within seconds during an outage to keep essentials running.

These upgrades maximize safety and convenience while your panel is open, saving you time later.

Breakers, Tripping, and Hot Spots: What to Know

Old or mismatched breakers cause nuisance trips and heat. We replace damaged or obsolete breakers with new ones that match the panel and meet current code. Once we identify the issue, simple breaker replacement often takes 30 to 45 minutes. If a breaker keeps tripping after replacement, we check for overloaded circuits or wiring faults and rebalance loads across phases.

Day‑Of Timeline: What to Expect

Most 100 amp to 200 amp service upgrades follow this schedule:

1. 8:00–9:00 a.m.: Arrival, protect floors, confirm work scope.
2. 9:00–10:00 a.m.: Power off, remove old panel, prep conductors and grounding.
3. 10:00 a.m.–1:00 p.m.: Install new 200 amp panel, breakers, and surge protector if selected.
4. 1:00–2:00 p.m.: Label circuits, perform testing and balancing.
5. 2:00–4:00 p.m.: Inspection window and utility reconnection, when applicable.

We keep you updated at each milestone and perform a final walkthrough before we restore power.

Local Insight: DFW Weather, Utilities, and Homes

North Texas storms bring lightning and grid swings. Whole‑home surge protection at your panel helps stop damage before surges hit your devices. Many mid‑century homes in Fort Worth, Irving, and Garland still have small panels or limited spaces. Upgrading to 200 amp service creates room for HVAC upgrades before peak summer. Our team also coordinates with Oncor for meter and service entrance needs so your cutover goes smoothly.

Aftercare: Maintenance, Testing, and Peace of Mind

A new panel is a long‑term asset. Keep it that way:

1. Schedule periodic electrical maintenance to check torque, labeling, and connections.
2. Review your surge protector status indicator after major storms.
3. Add dedicated circuits as your loads change rather than overtaxing existing ones.
4. Call if you see discoloration, buzzing, or repeated trips.

Berkeys offers electrical maintenance options that keep your system running safely and efficiently year‑round.
