Your electrical panel is the distribution hub for every circuit in your home, and most problems with it fall into two categories: something is failing and needs repair, or the panel is functional but no longer adequate for your home’s power demands and needs to be upgraded. Sometimes both are true at once. The warning signs for each are somewhat different, and a licensed electrician can tell you definitively which situation you are dealing with after an inspection.

Signs Your Panel May Need Repair

These are signs that something in your existing panel has failed or is failing:

  • Breakers that trip repeatedly without an obvious cause (an overloaded circuit you understand is different from a breaker tripping on a lightly loaded circuit)
  • A breaker that trips and will not reset, or that resets but does not hold
  • Burning smell, scorch marks, or discoloration near the panel or on the panel cover
  • The panel feels warm or hot to the touch
  • Buzzing, crackling, or humming sounds coming from the panel
  • Visible corrosion or moisture inside the panel
  • A Federal Pacific Electric (Stab-Lok) or Zinsco panel — these brands have documented histories of breakers failing to trip under overload conditions and are generally recommended for replacement regardless of apparent condition

Signs Your Panel Needs an Upgrade

An upgrade is usually about capacity rather than failure. Your panel may be functionally intact but simply not up to what your home needs today:

Your home has 100-amp service and you are trying to add a Level 2 EV charger, an electric vehicle, a hot tub, or a major appliance — these loads often push a 100-amp panel to or beyond its practical limits. The panel is completely full with no open breaker slots and no room for tandem breakers to add circuits. You are remodeling a kitchen or bathroom and the new appliances require dedicated circuits that do not exist. Lights dim noticeably when large appliances like your AC compressor or dryer start up. Or you are adding a significant addition to your home and need circuits for the new square footage.

The 100-Amp vs. 200-Amp Question

Homes built before roughly 1970 in the Denver area often have 100-amp service. This was adequate for the appliances of that era but is increasingly tight for modern households with multiple high-draw devices. A 200-amp service upgrade gives you more total capacity and more breaker slots. If you are adding an EV charger, converting from gas to electric appliances, or simply running out of room in the panel, a service upgrade is often the right move. In some cases where the utility feed itself must be upgraded, your electrician will coordinate with Xcel Energy as part of the process.

What an Inspection Actually Involves

A panel inspection by a licensed electrician goes beyond looking at breaker labels. It includes checking the condition of wiring connections at each breaker — loose connections are a leading cause of heat buildup and arcing. The inspector looks at bus bar condition, checks that wire gauges match breaker amperage ratings, verifies proper grounding and bonding, and notes whether AFCI and GFCI protection is in place where current code requires it. This gives you a complete picture of both the panel’s current condition and what would need to happen to bring it fully up to current standards.

Repair vs. Replace: The Tradeoff

Sometimes replacing a single failed breaker is the right answer. Other times, spending money on a repair in an aging panel that will need to be replaced in a few years anyway is not the best use of funds. An honest electrician will tell you which situation you are in and help you weigh the options. Done provides straightforward recommendations based on what we actually find — no upselling a panel replacement when a breaker swap is all that is needed, and no recommending a repair when replacement is clearly the safer long-term path.
