Commercial Electrical Panel Repair & Replacement in Bristol & Plymouth Counties
The electrical panel is the brain of your electrical system. And like any building component, they can wear out or become damaged to the point where you need repairs or replacements. Here are the most common signs your electrical panel is ready for replacement.
- Frequent Tripped Breakers: If your breakers trip often, it’s usually a sign that the panel is overloaded or failing to handle the demand.
- Flickering or Dimming Lights: Do your lights flicker or dim when you turn on another appliance? This can indicate an electrical panel that’s struggling to distribute power evenly across circuits.
- Buzzing or Crackling Sounds: Electrical panels should operate silently. If you hear buzzing, crackling, or hissing, something isn’t right. These noises may be caused by loose wiring, faulty breakers, or internal arcing.
- Outdated Panel Model: Some older panels may have safety issues and don’t meet current code requirements.
- You Still Have a Fuse Box: If your building uses a fuse box instead of a modern breaker panel, you’re long overdue for an upgrade. Fuse boxes are outdated, often underpowered, and pose a fire risk.
