Your panel talks before it fails. Here's how to listen.
Electrical warning signs fall into three tiers of urgency. Knowing which one you're in tells you exactly what to do right now.
Get out and call 911
Smoke · fire · visible arcing or sparking · a burning smell
- Smoke coming from the panel, a receptacle or the walls
- Any visible flame
- Visible arcing or sparking at the panel or anywhere in the home
- A burning, acrid or hot-plastic smell near the panel
Leave the house immediately and call 911 from outside. Do not go near the panel, do not try to shut off power yourself, and do not remove the panel cover. Once the fire department clears the scene, call us to evaluate and repair the electrical system before anything is re-energized.
Stop using the affected circuit and call us today
- Heat, or a panel cover that is warm to the touch
- Scorched, melted or discolored parts anywhere on the panel or a receptacle
- Buzzing, humming or crackling coming from the enclosure
- Moisture, rust or water staining in or near the panel
- A breaker that trips more than once on the same circuit
Turn off and unplug what's on that circuit, leave the panel cover in place, and call:(720) 665-6943
Do not remove the panel cover to look for the cause yourself. These signs mean something inside is already stressed — a same-day call is the right call, not an overreaction.
Not urgent, but worth doing
Schedule an inspection
None of these need a same-day call, but each one is a reason to get a panel looked at before it becomes a Tier 1 or Tier 2 problem.
- A panel over 25–30 years old, or a fuse box still serving the whole house
- A panel that is completely full, with tandem breakers stacked in
- A known-problem panel or breaker brand from a recalled or discontinued line
- Lights that dim when the AC or dryer starts, suggesting the service is at capacity
- A planned new load — EV charger, heat pump, hot tub, or a home addition
- A panel installed in a closet, bathroom or over a stairway
Aging equipment
Panel types worth a closer look
Screw-in fuse boxes
Common in pre-1960 Colorado homes. Fuses protect adequately when correctly sized, but they get replaced with oversized ones, and the panels themselves are usually 60 to 100 amps with no room to grow.
Known-problem breaker brands
Certain mid-century panel and breaker lines have a documented history of failing to trip reliably. If yours is one of them, insurers and inspectors will flag it, and replacement is the standard remedy.
Split-bus panels
Panels with no single main disconnect were normal into the 1970s. They aren't automatically unsafe, but they complicate shutting off the house and often have no capacity left.
Homeowner habits
Simple things that keep a panel healthy
These are the only checks a homeowner should do. Never remove the panel cover — everything below is done from the outside.
- Keep three feet of clear working space in front of the panel
- Never store paint, solvents or boxes against the enclosure
- Label circuits accurately and keep the directory legible
- Test GFCI and AFCI devices twice a year using their test buttons
- Use extension cords temporarily, never as permanent wiring
- Have the panel inspected before adding AC, a hot tub or an EV charger
What a panel inspection includes
We de-energize where required, remove the cover ourselves, and inspect the bus bars, breaker seating, terminations, neutral and ground bars, and the grounding electrode system. We check for heat signatures and moisture intrusion, verify the service size against a load calculation, and photograph everything.
You receive a written summary of what we found, what needs attention now, what can wait, and what — if anything — we'd recommend replacing.
FAQ
Safety questions we get asked
Is it safe to reset a breaker that tripped?
A breaker that trips once and holds after resetting can be a one-time overload. A breaker that trips again on the same circuit is telling you something is wrong. Stop using that circuit, do not keep resetting it, and call us to find out why.
Should I open my panel cover to look inside?
No. Never remove a panel cover yourself. The lugs and bus bars inside stay energized even with the main breaker off, and it takes training and the right equipment to work in there safely. Everything a homeowner should check — smell, sound, and whether the outside of the panel is warm — can be checked with the cover on.
How often should a panel be inspected?
Every three to five years for a panel in good condition, and sooner if the home is over forty years old, has been remodeled, or shows any warning sign on this page.
Do I need AFCI and GFCI protection?
Current code requires GFCI protection in kitchens, bathrooms, garages, basements and outdoors, and AFCI protection on most living-area circuits. Older panels often have neither. A panel replacement is the natural time to add both.
Is a full panel dangerous?
A full panel isn't automatically unsafe, but it invites the workarounds that are: double-tapped breakers, tandems used where they aren't listed, and circuits sharing neutrals they shouldn't. Those are the conditions that cause heat, and they're worth an inspection rather than a guess.
What about surge protection?
A whole-home surge protective device installed at the panel protects everything downstream from utility switching surges and nearby strikes. It's inexpensive when installed alongside a panel replacement.
What fixes each of these
Most of the warning signs above trace back to one of these jobs. Every one starts with an on-site look at the panel.
