Subpanel Installation in Virginia Beach, VA

A Master Electrician sizes and installs the subpanel, not a handyman.

We size the feeder to the load so the subpanel has the capacity you actually need.

Separate the grounding electrode and properly separate neutral and ground for outbuildings.

Room for the circuits a workshop, garage, addition, or shed requires.

Feeders are run and buried correctly for the distance and environment.

We pull the permit and pass inspection.

Capacity and space where you need it

When your main panel is full, or a garage, workshop, or addition needs several circuits, a subpanel adds both the capacity and the breaker space right where the load is. It is often the cleaner, more economical option than running many long circuits back to a crowded main panel.

Detached buildings need it done right

Feeding a detached garage, shed, or workshop requires a feeder, a separate grounding electrode at the building, and correctly separated neutral and ground; getting any of that wrong is a real hazard. This is precisely where a licensed electrician earns the call, and it is the most common thing do-it-yourself subpanels get wrong.

Sized for what you actually run

A workshop with heavy tools, a garage with an EV charger, or an addition with its own HVAC each draws differently, and the feeder and subpanel have to be sized for it. We run a load calculation so the subpanel carries what you need, with headroom, rather than tripping under the load it was built for.

Installation

Subpanels sized and wired to code.

• Subpanel installation for garages, workshops, and additions
• Detached-building subpanels for sheds, shops, and outbuildings
• Feeder sizing and installation from the main panel
• Separate grounding electrode and neutral-ground separation for detached structures
• Subpanels to add breaker space to a full main panel
• Pool, spa, and equipment subpanels

Circuits and related work

Everything the new panel feeds.

• New circuits for tools, appliances, and equipment
• Circuits for an EV charger, HVAC, or a workshop
• Buried or conduit feeder runs to detached buildings
• Coordinating a subpanel with a main panel or service upgrade
• Permitting and inspection

Attached versus detached

A subpanel in an attached garage, a short run from the main panel, is the simpler job, while feeding a detached shed or workshop, with a buried feeder and a separate grounding electrode, is a larger project. We tell you which one yours is and the price for it.

What moves the price

The feeder distance, whether it is buried or run in conduit, the subpanel size, the number of circuits, and whether the building is detached all affect the number. We size and price the job to your situation rather than a generic rate.

Janet's project was to connect a shed to the house wiring and install receptacles and switches in the shed, and she said it was scheduled quickly and done according to her specifications. Powering a detached building with its own circuits is exactly the work a subpanel is built for.

Real Customer Example | From a verified Google review (Janet F., November 2025)

This homeowner had Castles Electrical handle a new addition, including wiring, panel work, fixtures, and outlets, and called Wayne efficient and quick, saying they could not be more pleased. Bringing power and circuit capacity to an addition is our sweet spot.

Real Customer Example | From a verified Google review (The Boys, November 2025)

Kerri said Castles Electrical is the place she will use for all her electrical needs, praising Wayne as on time, very professional, and helpful in answering her questions. The kind of trust that comes from doing bigger jobs right the first time.

Detached garages, sheds, and workshops

Detached garages, sheds, and backyard workshops are common across the region, and each one that needs real power needs a subpanel with a proper feeder and its own grounding. We handle these detached-building subpanels correctly, which is a very different job from running a single circuit to an outbuilding.

Additions, bonus rooms, and ADUs

As homeowners add on, finish garages, or build accessory units, a subpanel is often the cleanest way to power the new space without overloading the main panel. We size and place a subpanel for the addition so the new area has the capacity and breaker space it needs.

Pools, spas, and equipment

With so many pools and spas here, a subpanel near the equipment is a common and tidy way to feed pumps, heaters, and lighting, and it pairs with the bonding these installations require. We install pool and equipment subpanels and coordinate bonding to keep them safe.

EV and workshop loads in the garage

More garages here are running EV chargers, shop tools, and other heavy loads, and a subpanel in the garage is often the smart way to supply them all rather than stringing long circuits from the main panel. We plan the garage subpanel around what you actually run.

Coastal feeder routing

Feeders to detached buildings often run underground here, where our soil and water table make correct burial depth, conduit, and moisture protection matter. We route and protect the feeder for our coastal conditions to keep it safe and reliable over the long term.

Sizing the feeder and subpanel

We run a load calculation on everything the subpanel will feed, then size the feeder and the panel to that with headroom, so it carries the load without running hot or tripping. Undersizing the feeder is a common mistake that leaves a subpanel unable to do the job it was installed for.

Separating neutral and ground correctly

At a subpanel, the neutral and ground must be kept separate, unlike at the main panel, where they bond, and getting this wrong is the single most common and dangerous subpanel error. We isolate the neutral and land the grounds correctly, which is fundamental to the panel being safe.

Grounding a detached building

A detached building fed by a subpanel needs its own grounding electrode and a feeder that carries a separate equipment ground, not a shortcut that relies on the neutral. We install the electrode and run the correct conductors, so a detached garage or shop is grounded the way code and safety require.

Feeder routing, burial, and conduit

Running a feeder to an outbuilding safely means the right conductor, the right conduit or cable, and the correct burial depth and moisture protection for the route. We properly route and protect the feeder, which matters even more in our coastal soil, so it lasts and stays safe.

Subpanel versus a service upgrade

Sometimes a subpanel solves the problem, and sometimes the real issue is that the entire service is undersized and needs to be upgraded first. We are honest about what your situation calls for, so you are not adding a subpanel to a service that cannot support it.
