Licensed Electricians in Waco, TX | Mr. Electric of Waco

Your home needs a panel upgrade if:

• You experience frequent breaker trips
• Your panel is over 25 years old
• You plan to install an EV charger or backup generator
• Your home still has a 100-amp panel

Most Waco homes built before 2000 have 100-amp electrical panels designed for homes with fewer appliances and lower electrical demand. Today's homes require 200-amp service to safely handle HVAC systems, kitchen appliances, home offices, electric vehicle chargers, and modern electronics. A panel upgrade provides the capacity your electrical system needs, eliminates safety hazards from outdated panels, and brings your home up to the 2023 National Electrical Code. The City of Waco requires a permit for panel upgrades, and the work must pass both rough and final inspections. We handle all permitting, perform the upgrade, and coordinate inspections so the job is completed correctly and legally.

Electrical panel upgrade costs in Waco vary based on panel amperage, the complexity of your existing electrical system, accessibility of your current panel location, and whether additional electrical code updates are needed. A standard upgrade from a 100-amp to 200-amp panel typically involves removing the old panel and installing the new panel box. We then reconnect and organize all circuit breakers, coordinate with Oncor for a temporary power disconnect, obtain City of Waco permits, and schedule required inspections. Additional costs occur if your service entrance cables need upgrading, the meter base requires replacement, or the main breaker location needs to be changed. We provide upfront pricing after inspecting your current system, explaining exactly what the upgrade involves, and identifying any code compliance issues that must be addressed.

The right backup generator size for your Waco home depends on what you want to power during an outage. A standby generator between 10kW and 12kW typically powers essential circuits, including the refrigerator, some lights, a few outlets, and your furnace or AC fan. A 14kW to 20kW unit powers most of your home, including HVAC, water heater, kitchen appliances, and multiple rooms. Whole-home generators rated 22kW and higher power everything in your home automatically when grid power fails.

After the February 2021 winter storm that left thousands without power for days, many Waco homeowners installed standby generators to maintain heating, refrigeration, and medical equipment during extended outages. Generator installation requires a dedicated natural gas line or propane tank, a concrete pad, proper clearances from your home and property lines, a transfer switch to isolate your home from the grid, and City of Waco permits. Our Waco electricians assess your electrical load, recommend the appropriate generator size, handle all permitting and utility coordination, and install the complete system.

The City of Waco requires permits for backup generator installations. As of September 1, 2025, Texas Senate Bill 1202 allows third-party inspections of home backup power systems in one- or two-family dwellings with electrical systems at 600 volts or less. You must apply for an Alternative Power Source permit through the City of Waco Citizen Self Service Portal and submit complete construction documents, including equipment specifications and electrical system drawings.

You also need to provide a sealed letter from a licensed engineer certifying the roof's structural integrity if roof-mounted equipment is involved. The installation must comply with the 2023 National Electrical Code, meet the manufacturer's clearance requirements, and include proper transfer switch installation to prevent backfeed into the utility grid. We handle all permit applications, coordinate required inspections, and ensure your generator installation complies with all code requirements.

A complete standby generator installation typically takes two to three days for the electrical work. Additional time will be needed for permit approval, utility coordination, and natural gas or propane connection. Day one involves setting the concrete pad and allowing it to cure. Day two includes positioning the generator, installing the transfer switch, running the electrical connections, and completing the gas line connection if your home has natural gas service. Day three covers final electrical connections, system testing, and final inspection.

Permit processing through the City of Waco takes one to three business days, depending on workload. If your home requires a new gas meter or propane tank installation, add another three to five days for utility or propane company scheduling. We coordinate every step, keep you informed throughout the process, and test the complete system before we consider the job finished.

EV charger installation requires assessing your electrical panel capacity, installing a dedicated 240-volt circuit, mounting the charging unit, and ensuring proper grounding and overcurrent protection. Most Level 2 home EV chargers require a dedicated 40- to 60-amp circuit. If your home has a 100-amp panel, you likely need to upgrade to a 200-amp panel before adding an EV charger circuit. The charger location matters for both convenience and code compliance.

We install the charger in your garage or on an exterior wall near your parking area, run the dedicated circuit from your panel to the charger location, install the appropriate circuit breaker and disconnect, mount the charging unit, and test the complete system. The City of Waco requires permits for EV charger installations, and the work must comply with the 2023 NEC Article 625 requirements for electric vehicle power transfer. Installation typically takes four to six hours once permits are approved, and your panel has adequate capacity.

Most homes with 100-amp panels do not have enough spare capacity for an EV charger circuit. A Level 2 EV charger requires a 40-amp to 60-amp dedicated 240-volt circuit. When you add up your HVAC system, water heater, kitchen appliances, dryer, and general lighting and outlets, a 100-amp panel is already near capacity. Adding an EV charger would overload the system and cause frequent breaker trips.

We perform a load calculation to determine your current electrical demand and available capacity. If your panel is at or near capacity, we recommend upgrading to a 200-amp panel before installing the EV charger. The panel upgrade provides the capacity your home needs for safe EV charging and accommodates future electrical additions. Both the panel upgrade and EV charger installation require City of Waco permits, and we handle both services.

The City of Waco requires permits for most electrical work, including:

• Panel upgrades
• New circuits
• Generator installations
• EV charger installations
• Service upgrades
• Substantial wiring modifications

Before permits are issued, electrical contractors must be registered with the City of Waco Inspection Services Department. They must provide proof of a Texas Master Electrical License, contractor liability insurance with minimum $300,000 coverage listing the city as certificate holder, and the license holder's contact information. Electrical work requires inspections at specific stages. Rough inspections occur before wiring is covered by walls or ceilings. Final inspections happen after all work is complete and before the system is energized.

For new construction with engineered concrete slabs, a UFER ground inspection must occur before the concrete pour. Inspection requests must be submitted through the Citizen Self Service Portal by 4 p.m. the day before the desired inspection date. We handle all permit applications, schedule required inspections, and ensure your electrical work passes every inspection.

A circuit breaker that trips repeatedly signals an overloaded circuit, a short circuit, or a ground fault. Do not keep resetting the breaker. If the breaker trips immediately when you reset it, a short circuit or ground fault exists somewhere on that circuit. If the breaker trips after several minutes or when you use certain appliances, the circuit is overloaded. Unplug everything on that circuit and reset the breaker once. If it holds, plug devices back in one at a time to identify the cause of the trip.

But if the breaker trips with nothing plugged in, the problem is in the wiring. Call us for an electrical inspection. We trace the circuit, identify the fault location, and make the necessary repair. Older Waco homes often have circuits serving too many outlets and appliances. The solution involves installing additional circuits to distribute the electrical load properly.

Flickering lights point to loose connections, an overloaded circuit, utility-voltage fluctuations, or a failing breaker. If lights flicker throughout your home when large appliances like your HVAC system or water heater turn on, your electrical panel is undersized for your home's demand. If lights flicker in one room or area, the problem is a loose connection in that circuit. Loose connections create resistance, which generates heat and degrades wire insulation over time.

Check if the flickering occurs only during high wind or storms. If so, the issue is likely with the utility service connection at the weatherhead or meter base. We inspect your electrical system, identify the source of the flickering, and make the appropriate repair. For homes with undersized panels, we recommend upgrading to larger panels to ensure stable power delivery throughout your home.

The 2023 National Electrical Code (NEC) is the minimum standard for all electrical work in Texas, adopted by the Texas Department of Licensing and Regulation. All electrical work permitted through the City of Waco must meet or exceed the 2023 NEC requirements. When we upgrade older Waco homes, we bring the existing electrical systems up to current code during the work. This ensures your home's electrical system meets modern safety standards and passes inspection. The 2023 NEC includes updated requirements for:

• Arc-fault circuit interrupter (AFCI) protection
• Ground-fault circuit interrupter (GFCI) protection in more locations
• Tamper-resistant receptacles in all areas accessible to children
• Outdoor outlet spacing and GFCI protection
• Dedicated circuits for specific appliances
• Proper grounding and bonding methods
• EV charging equipment installation standards

Many older Waco homes need partial or complete rewiring. With the median home construction year of 1977 and thousands of homes built in the 1940s through 1960s in neighborhoods like Cameron Park and North Waco, outdated wiring is common. Homes with knob-and-tube wiring, aluminum wiring, cloth-insulated wiring, or wiring that has been modified multiple times over the decades present safety concerns. Signs your home needs rewiring include:

• Frequently tripping breakers
• Two-prong outlets without ground wires
• Discolored or warm outlet covers
• A burning smell near outlets or switches
• Flickering lights
• Outlets that spark when you plug something in
• An electrical panel with fuses instead of breakers

A complete rewiring involves installing new wiring throughout your home, upgrading your electrical panel, and installing modern grounded outlets. We will also add GFCI and AFCI protection where required, and bring your entire electrical system up to the 2023 NEC. We inspect your home's wiring, identify potential safety hazards, and provide a detailed recommendation and quote for the necessary upgrades.

Call us at the number on this page or request an appointment online. We'll schedule a convenient time to visit your home. We inspect your electrical panel, check outlets and switches, and test GFCI protection. We examine visible wiring, assess your panel capacity and condition, and identify safety hazards. At the end, we provide a written report with our findings and recommendations. The inspection typically takes 45 minutes to 1 hour, depending on your home's size and the complexity of its electrical system. We offer complimentary electrical safety inspections for Waco homeowners. There is no obligation and no pressure. You receive a clear assessment of your electrical system's condition and a detailed quote for any recommended repairs or upgrades.

Whole-home surge protection installs at your electrical panel and protects every circuit in your home from voltage spikes caused by lightning strikes, utility switching, and grid fluctuations. Waco experiences frequent severe thunderstorms with lightning activity. A nearby lightning strike sends thousands of volts through power lines into homes. Plug-in surge protectors offer limited protection for individual devices. A whole-home surge protector installed at your panel stops surges before they reach any outlet or appliance. The device diverts excess voltage to ground, protecting sensitive electronics, appliances, HVAC systems, and anything plugged into your home.

After significant storms that caused widespread power outages in Central Texas, many Waco homeowners experienced damaged electronics and appliances from power surges when electricity was restored. Whole-home surge protection prevents this damage. Installation takes about two hours and involves mounting the surge protection device in your panel, connecting it to your main bus bars, and running a ground wire to your grounding system.

Electrical emergencies happen at any time. If you smell burning near outlets or your panel, see sparks or smoke, experience a complete power loss in your home while neighbors have power, or have a breaker that will not reset after an overload, call us immediately. We provide 24/7 emergency electrical services in Waco, Hewitt, Woodway, Robinson, and the surrounding areas of McLennan County. Our emergency response team identifies the problem, makes the home safe, performs necessary repairs, and restores power when possible. Electrical fires and electrocution hazards are issues that require immediate professional attention. Never attempt to diagnose or repair electrical emergencies yourself.

Ground-fault circuit interrupter (GFCI) protection detects current leakage and shuts off power within milliseconds to prevent electrocution. GFCI outlets have TEST and RESET buttons. The 2023 NEC requires GFCI protection for all outlets in bathrooms, kitchens within six feet of sinks, garages, unfinished basements, crawl spaces, outdoor outlets, outlets in utility rooms with sinks or water sources, and outlets within six feet of bathtubs and showers. Older Waco homes often lack GFCI protection in required locations. Water and electricity are a dangerous combination. A person touching an electrical device while standing on a wet surface or touching a grounded object completes a circuit through their body. The GFCI detects this current imbalance and cuts power before serious injury occurs. We install GFCI outlets in all required locations and test them to ensure proper operation. Installation takes about 30 minutes per outlet.

We recommend electrical safety inspections every 3 to 5 years for homes under 25 years old and every 1 to 2 years for homes over 40 years old. Schedule an inspection immediately if you purchase an older home, experience frequent breaker trips, plan a major renovation, notice burning smells or discolored outlets, hear buzzing sounds from your panel, or prepare to install high-demand equipment like an EV charger or backup generator.

Many electrical problems develop gradually. A loose connection heats up slowly over months or years before causing a fire. An overloaded circuit may function for years before failing. Regular inspections catch these problems early when repairs are simple and inexpensive. We inspect your panel, test circuits, check grounding systems, look for code violations, and identify safety hazards before they become emergencies.
