Does Your Austin Home Need an Electrical Panel Upgrade?

Your electrical panel is the heart of your home's electrical system. Every circuit in the house runs through it. Every light, outlet, appliance, and HVAC system draws power from it. When the panel cannot keep up with demand, you get tripped breakers, dimming lights, and real safety concerns.

Many Austin homes — especially those built before 1990 — are running on original electrical panels that were never designed for how we use electricity today. EV chargers, home offices with multiple monitors, smart home systems, upgraded HVAC equipment, and kitchen appliances that did not exist 30 years ago all draw power from a panel that was sized for a simpler era.

Here is how to tell whether your panel needs an upgrade and what the process looks like in Austin.

Signs Your Panel Needs an Upgrade

Frequent Breaker Trips

An occasional breaker trip is not alarming — it means the breaker did its job protecting the circuit. But if you are resetting breakers every week, or if the same breaker trips repeatedly, the panel is overloaded or the breaker itself is failing. In older Austin homes in Crestview, Brentwood, and North Loop, we regularly see panels where homeowners have learned to live with frequent trips, avoiding running certain appliances at the same time. That is not normal, and it is not safe long-term.

Double-Tapped Breakers

Open your panel cover and look at the breakers. Each breaker should have one wire connected to it. If you see two wires shoved into a single breaker terminal, that is double-tapping. It is a code violation, a fire hazard, and a clear sign the panel does not have enough circuits for the home's needs. Double-tapping shows up on virtually every home inspection report in Austin for pre-1990 homes.

Federal Pacific or Zinsco Panels

If your panel has FEDERAL PACIFIC, FPE, or STAB-LOK printed on it, you have a known safety concern. Federal Pacific Electric panels were installed in millions of American homes from the 1950s through the 1980s, and extensive testing has shown that their breakers fail to trip at alarming rates. A breaker that does not trip when it should means the circuit overheats without protection — a direct fire risk.

Zinsco panels (also sold under the Sylvania brand) have similar issues. The breakers can fuse to the bus bar, preventing them from tripping during an overcurrent event. Both Federal Pacific and Zinsco panels should be replaced. We replace them regularly throughout older Austin neighborhoods, and every electrician and home inspector in the area flags them on sight.

Adding Major Appliances or Systems

If you are planning to install any of the following, your panel likely needs assessment and potentially an upgrade:

• EV charger (Level 2 requires a dedicated 50-amp, 240-volt circuit)
• Hot tub or pool equipment
• Tankless water heater (electric models pull 100+ amps)
• Second HVAC system or mini-split addition
• Workshop equipment (welder, compressor, CNC)
• Home addition or ADU (accessory dwelling unit)

Adding any of these to a 100-amp panel that is already near capacity is not possible without upgrading to 200 amps. Even a 200-amp panel may need a subpanel if you are adding several high-draw circuits at once.

Homes with Original 100-Amp Panels

Most Austin homes built before 1980 have 100-amp electrical panels. Many homes built in the 1980s and early 1990s also have 100-amp service if the builder was conservative. A 100-amp panel was adequate for a home with a gas stove, one AC unit, and a handful of outlets per room. It is not adequate for a modern Austin household running central AC, an electric dryer, a home office, a dozen smart devices, and contemplating an EV charger.

The standard modern residential panel is 200 amps. Upgrading from 100 to 200 amps gives you headroom for current needs and future additions without constant concern about overloading the system.

The Upgrade Process in Austin

An electrical panel upgrade in Austin involves more than swapping out a box. Here is what the process looks like from start to finish.

Assessment and Proposal

Our licensed electricians start with a full assessment of your current panel, wiring, and electrical needs. We look at the panel brand and condition, the number of circuits and their loads, the condition of the meter base and service entrance cable, and any planned additions that will increase demand. You receive a written proposal with the full scope of work before anything starts.

Permitting

Electrical panel upgrades in Austin require a permit from the City of Austin Development Services Department. We pull the permit, schedule all inspections, and handle any corrections. The homeowner does not need to visit the permit office or deal with inspectors directly.

Austin Energy Coordination

This is the step that makes Austin panel upgrades different from most cities. The electric meter on your home belongs to Austin Energy (or the local utility if you are in Pflugerville, Round Rock, or another surrounding city). Upgrading the panel requires Austin Energy to disconnect the meter before we can work on the service entrance, and then reconnect it after the work is complete and inspected.

We coordinate the entire process with Austin Energy: scheduling the disconnect, completing the upgrade, passing the city electrical inspection, and scheduling the reconnect. The disconnect and reconnect typically happen on the same day — your home is without power for the hours it takes to complete the swap, not for days. We schedule the work to minimize inconvenience.

The Physical Work

The upgrade itself involves removing the old panel, installing a new 200-amp panel with modern breakers, replacing the meter base if required by Austin Energy, upgrading the service entrance cable from the meter to the panel, installing a new grounding system if the existing one does not meet current code, and reconnecting all existing circuits to the new panel with proper labeling.

If the existing wiring throughout the house is in good condition (copper, properly sized, undamaged), it connects to the new panel without modification. If we find aluminum wiring, undersized circuits, or other issues during the upgrade, we discuss the options before proceeding.

Arc Fault and Ground Fault Protection

Modern electrical code requires arc fault circuit interrupter (AFCI) breakers on bedroom circuits and ground fault circuit interrupter (GFCI) protection on kitchen, bathroom, garage, and outdoor circuits. When we upgrade a panel, we install AFCI and GFCI breakers where current code requires them. These breakers provide an additional layer of protection against electrical fires and shock hazards that older breakers do not offer.

For homes in Tarrytown, Hyde Park, and other older Austin neighborhoods where the original wiring may interact differently with AFCI breakers, we test each circuit after installation to ensure there are no nuisance trips. Older wiring with neutral-ground bonding issues can sometimes trigger AFCI breakers, and we correct those wiring issues as part of the upgrade if they arise.

Whole-House Surge Protection

We recommend installing a whole-house surge protector at the same time as a panel upgrade. Austin's summer thunderstorms produce frequent lightning strikes and power surges that can damage electronics, appliances, and HVAC equipment. A surge protector installed at the panel stops voltage spikes before they reach your home's circuits. Since the panel is already open and the electrician is already on-site, adding surge protection during an upgrade is efficient and cost-effective.

Inspection and Reconnection

After the upgrade is complete, the City of Austin inspector reviews the work. Once it passes inspection, we coordinate with Austin Energy to reinstall the meter and restore power. The entire process from start to finish typically takes one to two days of on-site work.

Common Questions About Panel Upgrades in Austin

How Long Will My Power Be Out?

Your home will be without power from the time Austin Energy disconnects the meter until they reconnect it after the upgrade passes inspection. We schedule the disconnect and reconnect on the same day whenever possible. Typical downtime is four to eight hours. We recommend planning the upgrade for a day when you can be flexible — charge your devices, prepare a cooler with food and drinks, and plan an activity away from the house if the weather is hot.

Do I Need to Be Home?

Someone over 18 needs to be home for the Austin Energy disconnect and reconnect, and to give our crew access to the panel area. You do not need to stand over our shoulder while the work is happening, but being available is helpful in case questions come up about specific circuits.

Will the Upgrade Affect My Smart Home Devices?

The brief power outage may require you to reconnect smart home devices, reset clocks, and reprogram garage door openers after power is restored. We walk through the house with you after the reconnect to verify everything is back online and functioning properly.

What About Homes in Surrounding Cities?

If you live in Round Rock, Cedar Park, Pflugerville, Georgetown, or Leander, the process is similar but the utility coordination is with your local provider (Oncor, PEC, or the municipal utility) rather than Austin Energy. The permitting process may differ slightly by jurisdiction. We handle all of this coordination regardless of which city you are in.

EV Charger Installations Almost Always Require Panel Assessment

With Tesla, Rivian, and other EVs becoming common in Austin driveways, EV charger installation has become one of our most frequent electrical services. A Level 2 home EV charger needs a dedicated 240-volt, 50-amp circuit — and that circuit draws more continuous power than anything else in most homes.

Before installing an EV charger, we always assess the panel. If you have a 200-amp panel with available space and capacity, we can often add the charger circuit without upgrading the panel. If you have a 100-amp panel or a 200-amp panel that is fully loaded, the charger installation needs to include a panel upgrade.

We install EV chargers as a standalone service and as part of panel upgrade projects. Either way, we handle the permit, the installation, and the inspection. Most EV charger installations — when the panel supports it — take half a day.

Cost Recovery and Long-Term Value

A panel upgrade is not a glamorous home improvement. Nobody walks into your house and compliments your breaker box. But it is one of the most important infrastructure investments you can make.

A modern 200-amp panel supports every electrical need your home has today and positions you for future additions — EV charger, solar panels, home battery, shop equipment, hot tub — without having to redo the panel again. It also eliminates the safety concerns associated with outdated panels and brings your electrical system up to current code.

For homeowners planning to sell, a panel upgrade removes a common inspection finding that can stall or complicate a transaction. Buyers and their inspectors flag old panels, Federal Pacific panels, and double-tapped breakers every time. Handling it proactively means one less negotiation item at closing.

If you are not sure whether your Austin home needs a panel upgrade, call us for a free assessment. We will evaluate your current panel, discuss your electrical needs, and give you an honest recommendation. If your panel is fine for now, we will tell you that too.
