Code-Compliant Sub Panel Solutions for Secure Power Distribution

As electrical demands increase in modern homes and businesses, your main panel often needs support to safely and efficiently distribute power. That’s where a sub panel comes in. At Sater Electric, we specialize in professional sub panel upgrades across Reno, Nevada, and surrounding areas including Sparks, Carson City, Sun Valley, Spanish Springs, and Incline Village. A subpanel serves as a secondary circuit hub, allowing for better power distribution to specific areas, such as garages, home additions, outbuildings, or EV charging stations.


If you're planning a remodel, adding a workshop, installing solar, or upgrading appliances, a properly sized and installed sub panel ensures your system can handle it—without risking overload or electrical hazards. With over 25 years of experience, our licensed electricians assess your current infrastructure, calculate future needs, and deliver precise, code-compliant installations that meet your requirements.


Sub panels are more than just an add-on; they’re critical for modern energy management. We coordinate permits, handle utility approvals, and install panels from trusted manufacturers like Square D and Siemens, ensuring long-term reliability and safe operation. Let us help you expand with confidence, whether you’re upgrading a single room or powering a full expansion. At Sater Electric, we design every sub-panel installation to meet your evolving power needs, safely, efficiently, and affordably.

Our Sub Panel Services

Sub Panel Installation

We install sub panels to safely extend power to garages, additions, or workshops. This expands circuit capacity without overloading your main panel, ensuring efficient power distribution for future needs. Sub panels are ideal when adding appliances or outlets to remote spaces. We customize each installation based on your structure’s layout and usage.

Sub Panel Replacement

Outdated or overloaded sub panels pose serious safety risks. We replace old units with modern, code-compliant panels that support today’s high-power needs. Our replacements prevent overheating, fire hazards, and frequent tripping. You’ll gain safer, more reliable circuit management—especially in areas that experience seasonal load fluctuations or multi-purpose use.

Load Balancing and Circuit Reconfiguration

We evaluate your panel layout and rebalance circuits to evenly distribute load. This improves voltage stability and reduces stress on breakers. By reconfiguring circuits, we minimize nuisance trips and power fluctuations. It's especially helpful in homes with sensitive electronics, high-wattage devices, or recent electrical additions.

Outdoor and Detached Structure Wiring

We install weather-rated sub panels to deliver safe, code-compliant power to ADUs, sheds, or garages. Conduits, junctions, and outlets are all designed for exterior use. Our work ensures reliable electricity even in harsh conditions. These solutions support lighting, appliances, and tools in remote or uncovered structures.

EV and Solar Integration Support

For systems located away from the main panel, we install dedicated sub panels to meet high-capacity demands. This is essential for EV chargers and solar inverters. We size and configure panels based on equipment specs. Our approach ensures stable performance, protects connected assets, and supports future expansion.

Permit and Code Compliance Services

We handle all permits, utility coordination, and inspections for sub panel work. Our deep familiarity with electrical codes ensures your project passes on the first try. We also provide detailed documentation for your records. From start to finish, we streamline compliance and eliminate common regulatory delays.

Benefits of Sub Panel Upgrades

Added Circuit Capacity

Sub panels allow you to add more circuits without upgrading the entire main service. This is perfect for expansions like home offices, hot tubs, or workshops that require dedicated breakers and improved electrical separation. It also helps manage high-load appliances more efficiently, minimizing the strain on your primary panel and reducing the risk of failure.

Safer Power Distribution

By offloading circuits from your main panel, sub panels reduce overload risk and prevent breaker trips. This leads to safer, more stable electrical performance and easier identification of faults in specific areas. With properly distributed loads, your system runs cooler, preventing overheating and enhancing overall household electrical safety.

Cost-Effective Expansion

Instead of a full electrical service upgrade, installing a sub panel offers a more affordable solution. It provides the flexibility to expand electrical service incrementally, which is ideal for phased renovations or growing energy needs. This keeps your project on budget while still supporting modern upgrades like EV charging or solar.

Better Organization

Sub panels separate circuits by function or location, making electrical systems easier to maintain and troubleshoot. This clarity is especially useful in multi-use buildings, rental units, or homes with detached structures. When issues arise, electricians can isolate and resolve them faster, reducing downtime and service costs.

Flexible Equipment Placement

Sub panels allow strategic power distribution across your property. You can add power where it's needed—such as a remote garage or new room—without re-routing all circuits back to the main panel. This flexibility saves on wiring costs and provides cleaner electrical layouts for future modifications.

Future-Ready Infrastructure

Installing a sub panel now prepares your property for future upgrades like solar, EV chargers, or HVAC additions. It adds the infrastructure needed for energy-conscious improvements down the line without redoing the main panel. It also increases your home’s resale appeal by showcasing electrical readiness for modern tech.

Power Expansion Done Right

At Sater Electric, we understand that every property has evolving electrical needs. Subpanel upgrades provide a smart and flexible way to expand circuit capacity without requiring a main panel overhaul. Whether you're building an addition, powering a detached garage, installing an EV charger, or integrating solar technology, our licensed electricians deliver reliable subpanel solutions tailored to your setup.

Backed by over 25 years of experience serving in Reno, Nevada communities, we ensure all work meets the latest safety codes and performance standards. From planning to inspection, we handle every detail—giving you safe, scalable, and future-ready electrical infrastructure you can trust.

Frequently Asked Questions

  • What is a sub panel and why would I need one?

    A sub panel is a secondary breaker panel that extends power to areas far from the main panel. It’s ideal for home additions, detached buildings, or high-demand areas like workshops and EV stations that require extra circuits.

  • How do I know if my current sub panel needs replacement?

    Common signs include frequent breaker trips, rust or corrosion, a buzzing sound, or insufficient capacity. If you’re adding new appliances or noticing performance issues, our electricians can inspect and recommend an upgrade if necessary.

  • Can I install a sub panel in a detached garage or shed?

    Yes, we specialize in installing weather-rated sub panels for detached structures. This setup allows safe and efficient power distribution, with all installations meeting NEC and local Reno-area code requirements.

  • Is a permit required for sub panel installation?

    Yes, permits are typically required for any panel upgrade or new sub panel installation. We handle all paperwork, inspections, and utility coordination to ensure full code compliance.


  • Can I use a sub panel for my solar or EV system?

    Absolutely. Sub panels are often needed to connect EV chargers or solar inverters, especially when these systems are located away from your main panel. We ensure proper sizing and compatibility with your technology.

  • How many circuits can a sub panel support?

    It depends on the size of the panel and your main service. Common sub panels support 4–20 circuits. We assess your load needs and install the right panel to support your electrical expansion.

  • Is it better to upgrade my main panel or install a sub panel?

    If your main panel has room and capacity, a subpanel may suffice for expansions. However, if your service is outdated or maxed out, upgrading the main panel may be a better long-term solution.

  • How long does sub panel installation take?

    Most installations take one day. However, timelines may vary based on complexity, permitting, and inspections. We provide a clear schedule upfront and work efficiently to minimize disruption to your home or business.
