Signs an Electrical Panel May Need Replacement

5 min read • Hattiesburg Property Guide

Your electrical panel is the central distribution heart of your home's power system. Older homes in Hattiesburg built decades ago were designed for 60A or 100A service, which cannot support modern HVAC units, EV chargers, and heavy electronics.

1. Rust or Corrosion: Moisture inside panel enclosures leads to dangerous corrosion on bus bars and breaker connections.

2. Warm Enclosures or Burning Smells: Indicates loose connections, arcing, or thermal overload.

3. Fuse Boxes or Outdated Brands: Federal Pacific, Zinsco, or old screw-in fuse boxes present documented failure risks and should be evaluated for replacement.

4. Planned Additions or EV Chargers: Adding Level 2 EV charging or HVAC upgrades usually requires stepping up to a 200-amp main panel.

Electrical diagnostics and repairs should only be performed by qualified, insured electricians following Mississippi building codes.
