This page is about the box as a whole. If one breaker is acting up, that is usually circuit breaker service. If the house simply needs more power than the utility connection provides, that is an electrical service upgrade, which often includes a new panel but goes further.
Repair Versus Replacement: How the Decision Gets Made
Repair makes sense when the panel is a sound, supported model with one localized problem: a scorched breaker slot, a loose main lug, a rusted cover, or a missing knockout filler. Replacement is usually recommended when the damage is widespread, parts are no longer made, the panel has run out of usable space, or the model has a poor track record.
Federal Pacific (Stab-Lok) and Zinsco panels are the two most commonly flagged. Many electricians and home inspectors recommend replacing them because of documented concerns about breakers that may not trip reliably or connections that overheat. A local electrician can identify the panel and explain the options in plain terms.
Common Reasons Homeowners Call About a Breaker Panel
A home inspector flagged the panel during a purchase or sale.
The panel is full and there is no room for a new kitchen, EV or HVAC circuit.
Water got into the panel from a leaky mast, siding or basement flooding.
Breakers feel hot, or there is a burnt smell near the panel.
The panel is a Federal Pacific (Stab-Lok) or Zinsco model.
An insurer asked about the panel's age or brand.
Warning Signs at the Panel
- Rust, white crust or water stains on or inside the cover.
- Discoloration, melted plastic or a scorched odor.
- A buzzing or crackling sound from the panel.
- Breakers that will not stay seated or feel loose.
- Fuses instead of breakers, or a panel that predates the house's additions.
What a Panel Repair or Replacement Involves
Repairs are often finished in one visit. A full panel replacement means scheduling a power shutoff, sometimes coordinating with the utility, transferring every circuit to the new panel, correcting grounding and bonding, and passing a local inspection before the work is closed out.
- Panel brand, age, rating and listing
- Bus bar and breaker connections for heat damage
- Main breaker or main lugs and service conductors
- Neutral and ground bars, bonding and grounding electrode
- Space for future circuits
- Moisture entry points above and around the panel
How it usually works
Call about the panel
Call to reach an independent local electrician and describe the panel, any brand on the label, and what you have noticed.
Panel evaluation
The electrician inspects the cabinet, breakers and connections and explains whether repair or replacement fits.
Permit and shutoff plan
For replacement, the permit, utility coordination and power-off window are arranged ahead of time.
Work, inspection and labeling
The panel is repaired or replaced, circuits are tested and labeled, and the local inspection is completed.
For homes around Chattanooga
Chattanooga has many homes from the early and mid 1900s in neighborhoods like Brainerd and North Shore, and some still have fuse boxes or panels added decades ago. Humid summers and basement panels can also mean corrosion. Homeowners preparing to sell often find panel questions come up first; see how to tell if a panel is outdated.
