How Much Does an Electrical Panel Upgrade Cost in Lawton?
permit feelabor costNEC code
Electrical panel replacement costs in Lawton typically run between $800 and $4,500, depending on the amperage you need and the condition of your existing wiring.
A basic 100-amp swap lands around $800–$1,200 in labor cost and materials. A 200-amp upgrade — the most requested residential job — usually falls between $1,300 and $2,500. The City of Lawton charges a permit fee of roughly $75–$200, and that inspection is mandatory under NEC code. If your meter base needs replacing or the grounding electrode system is outdated, expect $200–$500 added to the electrical box upgrade cost. Always ask your electrician for a line-item quote before signing anything.

Is Your 100 Amp Panel Too Small for Today's Homes?

A 100-amp service was adequate for homes built before 1970, but it struggles to handle the load a modern household places on it.
Running central AC, an electric range, a dishwasher, and a phone-charging station at the same time can push a 100-amp panel to its limit. A proper load calculation almost always confirms that upgrading to a 200-amp panel is the right move for homes over 1,200 square feet. The upgrade 100 amp to 200 amp process involves replacing the service entrance cable and main breaker, not just the cabinet itself. Upgrading to a 200-amp panel also makes your home compatible with EV chargers and heat pump systems that simply won't run reliably on a 100-amp service.

200 Amp vs 400 Amp: Choosing the Right Panel Size

A 200-amp main breaker panel is the correct choice for most Lawton homes between 1,500 and 3,500 square feet — it supports central HVAC, electric appliances, and a Level 2 EV charger without issue.
Homes larger than 4,000 square feet, or those with a detached workshop and multiple HVAC systems, should seriously consider 400-amp service, which is typically delivered as two 200-amp panels fed from a single meter. Brand matters less than you'd think, but Square D and Eaton are the two most common residential panels our network of licensed electricians install — both are widely available locally, carry solid warranties, and are accepted by Lawton inspectors without question. Your electrician will recommend the right fit after reviewing your existing service.

Outdoor and Small Panel Installations for Lawton Homes

Not every job involves replacing a full 200-amp indoor panel.
Detached garages, workshops, and pool equipment often need a dedicated subpanel fed from the main service — a 60-amp subfeed handles most of these situations cleanly and costs $400–$800 installed. Any panel placed outside must use an outdoor rated enclosure rated for the local climate, and Oklahoma's heat and storm exposure make a properly gasketed weatherproof panel critical for longevity. Our network of licensed electricians size outdoor subpanels carefully so you're not back in a year asking for more circuits. If you're adding an outdoor kitchen or a she-shed, a separate weatherproof panel keeps those loads off your main service and makes future expansions straightforward.

What Happens During a Panel Replacement?

To replace an electrical panel, your electrician starts by coordinating a utility disconnect with OG&E so the meter is pulled before any work begins — this is non-negotiable for safety.
Once power is isolated, they remove the old electrical panel box, label every circuit, and mount the new main breaker panel in the same location or a code-compliant new one. Grounding electrodes and bonding conductors are inspected and updated if needed — a step that's often skipped in older change-out jobs but is required under current code. After updating the electrical panel and terminating all branch circuits, the inspector verifies the work. Installing a new electric panel from start to finished inspection runs 4–8 hours on a typical single-family home. Replacing an electrical panel box without pulling a permit is never something a licensed electrician will do.

Smart Panels and Modern Electrical Upgrades

A smart breaker panel adds real-time load monitoring to your residential panel, letting you see exactly which circuits are drawing power from an app on your phone.
Brands like Leviton and Span offer full smart panel replacements, while Square D's QO line supports individual smart breaker add-ons that retrofit into an existing panel without replacing the whole cabinet. Load monitoring is especially useful for Lawton homeowners managing solar arrays or EV chargers, where knowing your real-time draw prevents nuisance tripping. The cost premium over a standard panel runs $500–$1,500 depending on the brand and circuit count. If you're already upgrading, adding smart breakers at installation is far cheaper than retrofitting them later.

New Breaker Box, Door, or Just a Cosmetic Fix?

Not every call about an old electrical panel actually requires a full new circuit breaker box — sometimes it's just a broken panel door or a missing breaker box cover that needs replacing.
A new breaker box door runs $30–$80 at any electrical supply house and snaps onto most Square D and Eaton cabinets in minutes. But if the electric service panel itself is a Federal Pacific Stab-Lok, a Zinsco, or any panel that's charred inside or corroded through, upgrading a breaker box is not optional — it's a fire risk. Upgrade my electrical panel calls that come in as cosmetic fixes sometimes reveal a far more serious problem underneath. Our network of licensed electricians will tell you honestly whether a new electrical panel is necessary or whether a simple breaker box cover replacement solves the problem for under $100.
