Electrical Installation

Types of Electrical Installations

Electrical installation covers everything from simple outlet additions to complete room rewiring. Whether you're building new or remodeling, proper installation ensures safety, code compliance, and future reliability. Each project type has specific NEC requirements and Cobb County permit procedures we manage for you.

Outlets & Switches

New outlets and switches are foundational to any electrical upgrade. We install standard 15A/20A duplex outlets, GFCI outlets (required in kitchens, bathrooms, laundries, and outdoor areas per NEC 210.8), and specialty outlets like USB receptacles or 240V plugs for appliances. Switches include standard toggles, dimmers, motion sensors, and smart switches from brands like Lutron and Leviton.

NEC Spacing: NEC Article 210 requires an outlet within 6 feet of any point along a floor plan and near countertops. We ensure your layout meets code and adds convenience where you need it most.

Cost: $5–$30 per outlet/switch plus $75–$150 labor per installation.

Lighting Installation & Dimming

Proper lighting design combines functionality, aesthetics, and energy efficiency. We install:

• Recessed Lighting: Installed in ceilings for clean, modern aesthetics. We ensure boxes are rated for fixtures and use proper spacing (typically 8–10 feet apart)
• Pendant Lights: Over islands, bars, and dining areas with dedicated switches or dimmer control
• Wall Sconces: Bathrooms, hallways, and living spaces at proper heights (36–48 inches for ambient, 60–66 inches for task)
• Chandelier & Specialty Fixtures: We verify ceiling box weight ratings (NEC 314) and install bracing for heavy fixtures
• Under-Cabinet Lighting: Kitchen task lighting on 20A circuits per NEC specifications
• LED Integration: Dimmers compatible with LED bulbs to prevent flicker

Lutron & Leviton Dimmers: We install lutron dimmer switches and Leviton smart controls. Not all dimmers work with all LED bulbs—we recommend compatible combinations.

Ceiling Fan Installation

Ceiling fan installation requires more than just swapping fixtures. NEC Article 314 specifies that outlet boxes must be rated for the fan's weight and vibration. Fans over 35 pounds require reinforced ceiling boxes with proper support rods. We verify existing boxes and upgrade when needed.

Our installation includes:

• Structural assessment and box upgrade if needed
• Proper wiring for light kit (if included)
• Dual-speed or smart control wiring
• Balance verification for smooth operation
• Warranty support (Hunter, Emerson, Minka brands)

Cost: $15–$50 for the fan + $100–$200 for installation and any box upgrades.

Dedicated Circuits for Appliances

High-demand appliances need their own circuits to prevent overloads and breaker trips. NEC Article 220 specifies circuit requirements by appliance:

• Refrigerators: 15A, 120V circuit (no other loads)
• Dishwashers & Garbage Disposals: 15A or 20A circuits
• Electric Ranges/Ovens: 40–50A, 240V dedicated circuit
• Electric Water Heaters: 30–50A, 240V dedicated circuit
• Dryers: 30A, 240V dedicated circuit
• EV Chargers (Level 2): 40–60A, 240V dedicated circuit
• Heating/Cooling Systems: Dedicated circuits per nameplate

Benefits: Prevents simultaneous demand on shared circuits, reduces breaker trips, and ensures appliances operate at full capacity.

New Construction vs. Remodel Wiring

Remodel Wiring Challenges: Older Marietta homes (pre-1980s) may have knob-and-tube wiring or aluminum conductors that complicate rewiring. We assess these and recommend safe upgrades.

Cobb County Permit Process

Any new wiring, circuit work, or most fixture installations require Cobb County permits. Here's the process:

1. Design Review: We assess your needs and design the electrical layout
2. Permit Application: We submit plans, calculations, and forms to Cobb County
3. Permit Approval: Typically 5–10 business days
4. Installation: We perform the work according to approved plans
5. Rough-In Inspection: County inspector verifies wiring before drywall
6. Final Inspection: Inspection after fixtures are installed and everything is complete

Cost: Permits typically cost $50–$150 depending on project scope. We handle all paperwork and coordinate inspection timing.

Wire Sizing & NEC Code Requirements

Correct wire sizing is critical for safety. Undersized wire creates heat and fire risk; oversized wire wastes money. NEC Articles 210 and 220 specify sizing requirements:

NEC 210: Branch circuit requirements and outlet spacing. NEC 220: Load calculations for circuit sizing. NEC 300: Wire protection and routing (conduit, raceways, etc.).

Installation Cost Breakdown

Costs vary by project scope, existing infrastructure, and permit requirements. Here's typical pricing:

Additional Costs: Permits ($50–$150), materials (wire, outlets, fixtures), and drywall repair if needed. We provide detailed estimates before starting work.

Quality Brands We Use

Typical Project Timeline

• Simple additions (2–4 outlets): 1–2 days (design, install, inspection)
• Remodeled room (kitchen, bath): 3–5 days (design, permits, rough-in, final)
• Whole-house rewire: 1–2 weeks (coordination with other trades, inspections)
• EV charger: 1 day (circuit installation + charger setup)
