FAQs
Why might my Dunlap home need an electrical panel upgrade?
Many houses in Dunlap were built when 60- or 100-amp fuse boxes were standard. Today’s appliances—HVAC systems, electric ranges, Level-2 EV chargers, hot tubs, etc.—can easily exceed that capacity. Upgrading to a modern 150- or 200-amp breaker panel gives you the amperage headroom to add new circuits safely, eliminates outdated fuses or obsolete "split-bus" breakers, and brings the service up to current National Electrical Code (NEC) and Sequatchie County requirements.
What warning signs indicate my current breaker panel is undersized or unsafe?
Frequent breaker trips, lights that dim when large appliances start, warm or buzzing breakers, scorched insulation, the smell of burning plastic, a panel manufactured by Federal Pacific, Zinsco, or Challenger, or the lack of a dedicated grounding conductor all point to a panel that needs replacement. Any of these issues should be inspected immediately to avoid fire or shock hazards.
How long will a panel upgrade take and will my power be off?
A typical residential service upgrade in Dunlap takes one full working day. Power is generally shut off for 4–8 hours while our licensed electricians remove the old panel, install the new meter base and main breaker, land all branch circuits, and perform torque verification. We coordinate the outage with Sequatchie Valley Electric Cooperative and schedule the final inspection so your service is re-energized the same day whenever possible.
Are permits and inspections required for a panel replacement in Dunlap?
Yes. Sequatchie County follows the Tennessee State Fire Marshal’s Office electrical permitting process. Our team pulls the permit, provides a one-line diagram and load calculation, and arranges for the state inspector to review the work. Utility crews will not reconnect power until the inspector signs off, so using a contractor who knows the local procedure is essential.
What size panel do most modern homes require?
For a typical single-family house up to 3,000 sq ft with central air, laundry equipment, and space for future EV charging, a 200-amp, 40-space panel is the new standard. Larger homes or properties with workshops may benefit from 300- or 400-amp services, often implemented with dual 200-amp panels. Our electricians perform a NEC Article 220 load calculation to right-size the service for your present and future needs.
How much does an electric panel upgrade cost and are financing options available?
In Dunlap, a straightforward 200-amp overhead service upgrade typically ranges from $2,200 to $3,000, including permit fees, materials, and labor. Underground services, relocation, or additional meter bases add cost. We provide fixed-price quotes after a free on-site assessment and offer 0% interest financing for up to 12 months to qualified homeowners, plus we’ll advise on any available TVA energy-efficiency rebates.
