New Panel & Sub-Panel Installation
The Shop and the Garage Get Their Own Power
New construction, an addition, a garage, or a workshop that needs its own power. We install main panels and sub-panels across Cheyenne, sized right, grounded correctly, permitted and inspected.
The Right Panel, Installed Right
When You Need a Panel Where There Wasn’t One
Electrical panel installation in Cheyenne, WY covers every situation where a new panel goes in rather than an old one coming out. A house under construction needs a main panel sized for its full design load. A finished basement, a bonus room, or a second-story addition often needs its own sub-panel so the new circuits do not overwhelm the main. A detached garage or a backyard shop needs power run to it and a panel of its own. Moonlight Electric Solutions handles all of it, from the load calculation through the final inspection.
What separates a panel installation from a panel upgrade or replacement is that there is no existing panel doing this job yet. That means the work starts further back. We size the panel for the load it will actually carry, run the feeder or service to it, set the grounding and bonding correctly, and lay out the breaker spaces so the circuits make sense for whoever uses the space. A sub-panel feeding a workshop is wired differently than a main panel for a new home, and a panel in a detached structure has its own grounding rules. Getting those details right is the difference between a panel that passes inspection and serves for decades and one that causes problems from day one.
Isaac Garcia, owner and master electrician licensed in Wyoming and Colorado, installs panels for builders, remodelers, and homeowners across Cheyenne and the surrounding communities. His experience wiring federal government facilities built a discipline around correct grounding, accurate load calculations, and clean, labeled installations that make future service easy. Whether you are a builder who needs a panel set on schedule or a homeowner adding a shop, every panel we install is sized to the load, wired to current code, permitted, and inspected.
Common Reasons to Install a New Panel
New home construction that needs its main service panel set. A finished basement or attic conversion that needs its own sub-panel. A detached garage, barn, or backyard shop that needs power and a panel run to it. A home addition that adds enough circuits to warrant a dedicated sub-panel. A workshop with welders, compressors, or dust collection that needs heavy dedicated circuits.
If your project needs a panel installed from scratch, call (307) 757-5553. We will size it, price it, and coordinate the schedule with your build.
What We Install
Panel Installation Services
New Construction Main Panels
For new homes, we install the main service panel sized to the home’s complete design load. We coordinate with the general contractor and the utility on service placement, set the meter base and main panel, establish the grounding electrode system, and lay out breaker spaces for every circuit in the plan plus room to grow. We schedule around the build so the panel is set and ready when the rough-in and inspection milestones arrive. This work pairs with our new construction electrical service.
Sub-Panel Installation
A sub-panel is a smaller panel fed from the main that provides dedicated breaker space in a specific area. We install sub-panels for finished basements, attic conversions, additions, and any part of the home that needs several new circuits. The sub-panel is fed with a properly sized feeder from the main, and we keep neutrals and grounds separated correctly, which is one of the most commonly botched details in sub-panel work. Done right, a sub-panel adds capacity exactly where you need it without touching the main service.
Detached Garage & Shop Panels
A detached garage, barn, or backyard shop needs power run to it and a panel of its own. We trench and run the underground feeder, set a panel in the structure, and establish a separate grounding electrode at the detached building as code requires. We size the panel for what you actually run out there, whether that is a few lights and outlets or a full shop with a welder, air compressor, and dust collection. Cold Wyoming winters also make a good place to add a circuit for a heater or block-heater outlets.
Addition & Remodel Panels
A significant addition or whole-home remodel often adds enough circuits that a new panel or sub-panel is the cleanest solution. Rather than cramming tandem breakers into a full main panel, we install a properly sized panel that gives the new space its own clearly labeled breakers. This keeps the electrical system organized, makes future service straightforward, and ensures the addition has the capacity it needs without overloading the original panel.
Dedicated Equipment Circuits & Grounding
Many panel installations exist to serve specific heavy loads: a hot tub, a well pump, a workshop machine, an air handler, or a backup generator interlock. We install the panel and the dedicated 240-volt circuits these loads require, with correct overcurrent protection and grounding. Proper grounding and bonding is the foundation of every panel we set, because it is what makes the breakers and surge protection work the way they are supposed to and what keeps the structure safe.
Our Process
How Panel Installation Works
Load Calculation & Panel Sizing
Every installation starts with a load calculation under the National Electrical Code. We add up the circuits and equipment the panel will serve, factor in growth, and size the panel and feeder accordingly. For new construction we work from the plans; for an addition, shop, or sub-panel we work from what you are actually adding. Correct sizing is what keeps the panel from running at its limit later.
Permit & Proposal
We pull the electrical permit with the City of Cheyenne and provide an itemized proposal covering the panel, feeder or service, grounding, breakers, trenching if needed, labor, and inspection. For builders, we align the schedule with your rough-in and inspection milestones so the panel never holds up the project.
Installation & Wiring
We mount and set the panel, run the feeder or service to it, install the grounding electrode system, land every circuit, install the breakers, and label the panel clearly. For detached structures we trench and run the underground feeder and set a separate ground. Every connection is torqued to spec and the layout is left clean and easy to read.
Testing & Inspection
We test every circuit for correct operation, polarity, and grounding, verify the breakers and any GFCI or AFCI devices, and confirm the panel is energized safely. The city electrical inspection is scheduled and passed, and you receive documentation of the installation for your records, your builder, and your insurance company.
Common Questions
Panel Installation FAQs
How much does it cost to install a new electrical panel or sub-panel?01
A residential sub-panel installation in the Cheyenne area is priced off the panel size, the length and routing of the feeder, and whether trenching is needed to reach a detached structure. A new construction main panel is priced as part of the overall electrical package for the home. Every job is quoted after a load calculation so you know the exact figure before work starts. Call (307) 757-5553 for a free quote.
Do I need a permit to install a panel or sub-panel?02
Yes. Installing a new main panel or sub-panel requires an electrical permit from the City of Cheyenne and a final inspection, because it adds to or alters your electrical distribution and must be properly grounded and bonded. We pull the permit, install to current National Electrical Code standards, and schedule the inspection as part of every job. Permitted, inspected work protects you at resale and with your insurance company. We never install a panel without a permit.
What is the difference between a panel installation and a panel upgrade?03
A panel installation puts in a new panel where there was not one before, such as a main panel for new construction or a sub-panel for an addition, garage, or shop. A panel upgrade increases the capacity of an existing service, usually from 100 to 200 amps. If your main is already full and you want to feed a new sub-panel, sometimes you need both: an upgrade to the main and an installation of the new sub-panel. Our load assessment makes the right path clear.
Can you run power and a panel to my detached garage or shop?04
Yes, this is one of our most requested installations. We trench and run an underground feeder from the house to the detached structure, set a panel inside, and establish a separate grounding electrode at the building as code requires for detached structures. We size the panel for what you run out there, whether that is lighting and a few outlets or a full shop with a welder, compressor, and heater. We handle the permit and inspection so the whole thing is done right.
How is a sub-panel different from just adding breakers?05
You can only add as many breakers as the main panel has spaces for, and many older panels are already full. A sub-panel is fed from the main with a single feeder and provides its own bank of breaker spaces in a new location, which is far cleaner than cramming tandem breakers into a packed main. It also puts the breakers for a space near that space, so the basement breakers are in the basement rather than across the house. For additions and finished spaces, a sub-panel is usually the better engineered solution.
Do you work with builders and general contractors?06
Yes. We install service panels for new homes and additions on builders’ schedules and coordinate with the general contractor and the utility on service placement and timing. We hit rough-in and inspection milestones so the electrical never holds up the project, and we keep installations clean and clearly labeled so future service and finish work go smoothly. Builders and remodelers across the Cheyenne area rely on us for panels that are sized right and pass inspection the first time.
