FAQs
What is an electrical panel upgrade and why might I need one in Tullahoma?
An electrical panel upgrade replaces an existing service panel (breaker box) with a new, higher-capacity unit—usually increasing service from 60-100 amps to 150-200 amps or more. Homes and businesses in Tullahoma often need upgrades when adding high-demand appliances (HVAC, EV chargers, hot tubs), renovating, or remedying obsolete panels such as Federal Pacific, Zinsco or fuse boxes. A modern panel delivers ample power, reduces nuisance breaker trips, lowers fire risk, and ensures compliance with the latest National Electrical Code (NEC) and Tullahoma Utilities Authority requirements.
How can I tell if my current electrical panel is outdated or unsafe?
Warning signs include: (1) breakers that trip or fuses that blow repeatedly, (2) lights dimming when large appliances start, (3) scorching, rust, or buzzing noises inside the panel, (4) a warm or hot panel cover, (5) lack of open breaker slots for new circuits, (6) insurance carriers flagging hazardous brands (e.g., Federal Pacific, Zinsco), and (7) amperage rating less than 100 A stamped on the main breaker. Any of these indicators should prompt a licensed electrician to perform a load calculation and safety inspection.
What electrical codes and local standards govern panel upgrades in Tullahoma?
Tullahoma follows the 2023 National Electrical Code (NEC) as adopted by the Tennessee Department of Commerce & Insurance. Key NEC articles include 230 (Services), 408 (Switchboards, Panelboards), and 310 (Conductors). The City of Tullahoma Building & Codes Department requires a permit before work begins and a final inspection after completion. The local utility (Tullahoma Utilities Authority) must also approve the service upgrade and may replace or resize the meter base. All work must be performed by a Tennessee-licensed electrical contractor and carry a one-year workmanship warranty at minimum.
What does the upgrade process look like and how long does it take?
1. Load calculation and proposal (1–2 days). 2. Permit application and utility coordination (3–7 business days, depending on utility scheduling). 3. On-site work: shutting off power, removing the old panel, upgrading service entrance cable, installing the new panel, labeling circuits, bonding/grounding, and re-energizing (typically 6–10 hours, completed in one day). 4. City inspection and utility reconnect (same day or next business day). 5. Final walk-through and documentation. During the change-out your power will be off for 4–8 hours, so plan for refrigeration and IT needs. Our team supplies temporary lighting as needed and restores critical circuits first.
How much does a panel upgrade cost in Tullahoma and what factors affect price?
For most single-family homes, a 200-amp service upgrade runs $1,800–$3,500, while commercial installations or larger 400-amp services range from $3,500–$7,500. Pricing depends on: service size, panel brand (e.g., Siemens, Square D QO), need for new grounding electrode system, meter base relocation, conduit runs, drywall/finish repairs, and after-hours or emergency scheduling. We provide a fixed, itemized quote up-front and offer financing options through TVA-approved lenders.
Will you handle permits and inspections, and will I be without power during the upgrade?
Yes. Our licensed electricians obtain the City of Tullahoma electrical permit, coordinate meter disconnect/reconnect with Tullahoma Utilities Authority, and schedule the final inspection. You will experience a planned outage of approximately 4–8 hours while the old panel is removed and the new one wired. We notify you of the exact window, advise you to power down sensitive electronics, and can supply a temporary generator or UPS upon request. After the inspector signs off, we re-energize the panel, label every circuit, and provide compliance documentation for your records and homeowners insurance.
