Signs Your Commercial Property Needs a Panel Upgrade
Your electrical panel is the heart of your commercial building’s power system, but it's often overlooked until problems arise. If your business is experiencing any of the following issues, it may be time for a professional panel or service upgrade:
Frequent Breaker Trips
Are your breakers constantly tripping when equipment is running? This is a sign that your current panel can’t handle your power demands. Frequent resets aren’t just annoying; they signal an overloaded or outdated system.
Flickering or Dimming Lights
If your lights dim when machinery starts or flicker for no clear reason, your electrical system might be strained. This can also indicate loose connections or voltage drops due to insufficient service capacity.
Limited Outlets or Circuits
Running extension cords and power strips to get by? A lack of available circuits suggests your panel is maxed out, and adding more outlets without a proper upgrade can be dangerous.
Adding New Equipment or Expanding
Upgrading your HVAC, adding new machines, or expanding your workspace? These changes often require more amperage than your current panel can safely provide. A service upgrade ensures you have room to grow.
Warm or Buzzing Electrical Panel
Panels that feel warm to the touch, emit a burning smell, or make buzzing sounds may have damaged breakers, loose wiring, or internal corrosion, all serious hazards that require immediate attention.
Aging or Outdated Electrical Panels
If your panel is more than 25–30 years old, it likely wasn’t built for today’s energy demands. Some older panels (like certain Zinsco or Federal Pacific brands) are even known fire risks and should be replaced as soon as possible.
