Yes, you can upgrade a breaker box for more power. In fact, many Austin‑area homeowners need an electrical panel upgrade when adding a Level 2 EV charger, new HVAC, or a backyard workshop. If your lights flicker or breakers trip, a right‑sized, code‑compliant upgrade restores safety and capacity. Below, we explain when it makes sense, what it costs, the steps involved, and how to do it without headaches.
Breaker Box vs. Electrical Panel: What Are We Really Upgrading?
Most people say breaker box. Electricians say electrical service panel. Same idea. It is the central hub that receives power from the utility and distributes it to individual circuits. Upgrading the panel increases safety, available amperage, and room for future circuits.
Key components include:
- Service entrance conductors and meter.
- Main disconnect and busbars.
- Circuit breakers, including AFCI and GFCI where code requires.
A modern upgrade may also include a whole‑home surge protective device at the service. The 2020 National Electrical Code requires surge protection on dwelling unit services, which is a smart add‑on during a panel change.
When Does a Breaker Box Upgrade Make Sense?
You gain real value when your current service cannot safely handle today’s loads. Common triggers:
- Adding a Level 2 EV charger that draws a 240‑volt, 40‑60 amp circuit.
- Installing new HVAC equipment or heat pumps.
- Frequent breaker trips, warm panel cover, or buzzing.
- Lights dim when large appliances start.
- Federal Pacific Electric or Zinsco panels, which are known for failing to trip.
- Major remodel, accessory dwelling unit, or backyard shop.
If any of these apply, an upgrade improves safety and performance. In Austin, we often replace 100‑amp services with 200‑amp panels to support EVs, induction ranges, and future solar‑plus‑storage.
How Much Power Do You Actually Need?
Right‑sizing starts with a load calculation. We total the square footage, fixed appliances, HVAC, EV charging, and demand factors. For many single‑family homes, 200 amps is the sweet spot. Large properties with workshops or pool equipment may need 225‑ to 320‑amp service.
Rules of thumb:
- 100 amps works for small homes with gas appliances and limited loads.
- 150 amps bridges older homes and modest upgrades.
- 200 amps supports most modern homes and EV charging.
- 225 to 320 amps covers larger estates, multi‑HVAC systems, or future battery storage.
A formal calculation and panel inspection prevent guesswork. It also keeps your project compliant with local code and utility requirements.
Can You Just Add More Breakers?
Not safely if you are already at capacity. Tandem or cheater breakers are not a substitute for an undersized panel. If your busbars are full or the panel runs hot, adding circuits can push equipment past its rating. The clean, lasting solution is a panel with more spaces and the right main service size.
What About EV Chargers and Heat Pumps?
Level 2 chargers often require a 40‑ to 60‑amp, 240‑volt circuit. Many older 100‑amp services cannot share that load with HVAC, ovens, and dryers. Before we install an EV circuit, we run a load assessment. If an upgrade is needed, we handle panel and meter work, permits, and inspection. That sequence is also required for Austin Energy EV charger rebates, and we provide documentation for the application.
Safety, Code, and Permits in Austin
Electrical service work is not a DIY task. In the City of Austin and surrounding jurisdictions, panel upgrades require:
- An electrical permit and utility coordination.
- NEC‑compliant grounding and bonding.
- Proper labeling, AFCI and GFCI protection where required, and a listed surge device at the service.
- Final city inspection.
SALT manages the permit, meter coordination, and inspection. We replace aging feeders, verify grounding electrodes, and label circuits so future service is simple and safe.
The Step‑by‑Step Process We Follow
We use a predictable process so your power downtime is minimal and the results are organized.
- Load Assessment: We confirm the current panel can safely support new demand.
- Upfront Options: You receive written, flat‑rate choices with financing, including 0% interest for up to 18 months on qualifying jobs.
- Permits and Scheduling: We secure the permit and coordinate with the utility.
- Installation Day: Licensed, background‑checked electricians arrive with the new panel, breakers, grounding hardware, and surge device.
- Power Cutover: We safely de‑energize, replace equipment, and migrate circuits.
- Labeling and Testing: We label each circuit and test AFCI and GFCI protection.
- Final Inspection and Documentation: We coordinate the inspector’s visit and issue a digital folder with photos and videos of the work.
Most residential upgrades take one working day with brief downtime. Complex meter or service‑mast changes can add time.
How Much Does a Breaker Box Upgrade Cost?
Costs vary by service size, condition of existing equipment, and code updates needed. Budget factors:
- Amperage upgrade, such as 100 to 200 amps.
- Meter base and service mast condition.
- Grounding and bonding updates.
- Surge protection and arc‑fault breakers.
- Panel location changes or conductor reroutes.
Flat‑rate pricing avoids surprises. We provide good, better, best options and financing. Many homeowners use the 0% for up to 18 months plan on qualifying projects to spread payments without interest.
Signs You Should Not Delay
Electrical issues can escalate. Call for an assessment if you notice:
- Burning odor or scorched breakers.
- Breakers that will not reset or trip repeatedly.
- Warm panel cover or buzzing.
- Flickering when your AC or oven runs.
- A Federal Pacific Electric or Zinsco panel.
These are safety flags. An upgrade reduces fire risk and stabilizes voltage for sensitive electronics.
Breaker Box Upgrades and Whole‑Home Generators
If you plan for standby power, the panel and transfer switch must be designed together. We integrate automatic transfer switches, right‑size the generator load, and coordinate gas line work with our in‑house plumbing team. Multi‑trade coordination avoids finger‑pointing and keeps your inspection schedule on track.
Do You Need Maintenance After the Upgrade?
Yes. Panels are low‑maintenance but not no‑maintenance. Thermal cycling can loosen lugs over time and dust can collect. Our SALT+ membership includes a yearly electrical safety inspection, priority scheduling, and a 10 percent repair discount. This helps protect your investment and keeps your new panel in top condition.
What Makes a Professional Upgrade Different?
Beyond new hardware, a professional installation delivers:
- A clean, labeled panel that future technicians can service quickly.
- Correct torque on lugs, verified with a calibrated tool.
- Neat wire management that improves airflow and troubleshooting.
- Proper AFCI and GFCI placement to meet current code.
- Surge protection at the service for downstream electronics.
SALT backs panel upgrades with a lifetime guarantee on repairs and installations. You also get video summaries of findings and a digital record for insurance or resale.
Local Insight: Austin Homes and Growth Loads
Central Texas homes are electrifying at a fast pace. We see more induction ranges, heat pump water heaters, and EVs in Round Rock, Cedar Park, and Georgetown. Planning for a 200‑amp service today can avoid another upgrade in a few years. If you are in Austin Energy territory, our permit and rebate documentation keeps projects moving without paperwork delays.
Can You Keep the Old Location?
Often yes, if the location meets clearance, height, and working space rules. In tight garages or closets, code may require relocation. We assess clearances and moisture exposure, then present options. When relocation is needed, we patch and make tidy penetrations to maintain a finished look.
Timeline and Downtime
Typical timeline from first visit to inspection is one to two weeks, depending on utility scheduling and permits. Day‑of power downtime is usually four to eight hours. We plan cutovers so refrigerators and critical loads are protected and back online quickly.

Frequently Asked Questions
How do I know if I need more power or just new breakers?
If breakers trip often, the panel is warm, or lights dim with large loads, you likely need more capacity. A load calculation tells us whether a 150‑ or 200‑amp upgrade is right. Simply swapping breakers does not increase the panel’s safe capacity.
Is a permit required for a breaker box upgrade in Austin?
Yes. Service upgrades require a permit, utility coordination, and a final inspection. We handle permits, schedule the inspection, and provide documentation. This keeps your project compliant and avoids delays.
How long does a panel upgrade take?
Most residential upgrades take one day on site with four to eight hours of downtime. The overall timeline from assessment to inspection is typically one to two weeks, depending on permitting and utility scheduling.
Will a 200‑amp panel raise my electric bill?
No. The panel’s rating does not increase usage. Your bill reflects what you use. A larger panel simply provides safe capacity and room for additional circuits like EV chargers or new HVAC equipment.
Can I add a Level 2 EV charger without upgrading the panel?
Sometimes, but many 100‑amp services do not have spare capacity. We run a load assessment first. If the panel is undersized, we upgrade it, then install the EV circuit. This approach also supports Austin Energy rebate documentation.
Conclusion
Yes, you can upgrade a breaker box for more power, and in many Austin homes it is the safest way to support EV charging, modern HVAC, and future projects. A permitted, right‑sized electrical panel upgrade improves reliability and protects your investment. Ready to get started today?
