You do not want to fail an electrical inspection. If an electrical inspection flags hazards, you could face delays, insurance issues, or safety risks. Here are the top red flags that cause an electrical inspection to fail, plus pro fixes you can tackle now. If you need help in Sterling, Fort Morgan, or across the Eastern Plains, Circuit Makers Electric makes passing your next electrical inspection simple and stress-free.
1) Overloaded, outdated, or unsafe electrical panels
Your main service equipment is the first stop in any electrical inspection. Common fail points include double-tapped breakers, overheated bus bars, mislabeled circuits, and obsolete or recalled gear. If your home still has a fuse box or certain legacy panel brands, you will likely face upgrade recommendations. Capacity mismatches are also frequent. A modern home with EV charging, hot tubs, and remodeled kitchens can overwhelm a small panel.
Key facts inspectors rely on:
- Working clearance must be at least 30 inches wide and 36 inches deep in front of the panel, with 6.5 feet of headroom (NEC 110.26).
- Service equipment must be listed, labeled, and installed per manufacturer instructions.
Pro fix:
- Schedule a panel assessment to size your service correctly.
- Correct double taps with approved devices or additional spaces.
- Replace unsafe or obsolete panels and breakers.

“Matthew was very knowledgeable... suggested a new box... installed new wiring, breakers and a new 220 voltage box... always looking at the safety for the consumer... fair pricing... kept in constant communication.”
2) Missing or miswired GFCI and AFCI protection
Ground-fault circuit-interrupter (GFCI) and arc-fault circuit-interrupter (AFCI) protection are frequent reasons for failed inspections. Kitchens, bathrooms, garages, laundry areas, basements, and outdoor receptacles require GFCI protection in most cases (NEC 210.8). Bedrooms and many living areas require AFCI protection to mitigate arcing hazards (NEC 210.12).
Red flags:
- GFCI devices missing where required or installed but miswired.
- AFCI breakers missing on qualifying branch circuits.
- Bootleg grounds or shared neutrals wired incorrectly.
Pro fix:
- Audit required locations and add GFCI receptacles or GFCI/AFCI breakers.
- Correct neutral and ground terminations per code and manufacturer specs.
- Test devices with a GFCI/AFCI tester to verify trip and reset.
As we say, “Do you do safety inspections? Panels – Smoke Detectors – GFCI – Arc Fault – We do it all.”
3) Poor grounding and bonding
Improper grounding and bonding create hidden shock and fire risks. Inspectors look closely at the grounding electrode system and bonding of metal piping.
Common fails:
- No bond to the metal water service or to other electrode systems.
- Loose, corroded, or undersized grounding electrode conductors.
- Detached buildings fed by feeders without a grounding electrode system at the structure.
Pro fix:
- Verify the grounding electrode system meets NEC Article 250, including bonding jumpers and listed clamps.
- Replace corroded or damaged conductors and terminations.
- Install ground rods or other electrodes where required and bond metal systems.
Local tip: Many homes around Sterling and Fort Morgan have older water service bonds that were never updated during panel changes. An inspector will catch that quickly.
“He was methodical at seeking out and solving the problem. I am very pleased with the response and service.”
4) Damaged, undersized, or aluminum branch wiring and bad terminations
Wiring visible in attics, basements, and garages tells an immediate story. Inspectors often fail homes for backstabbed receptacles, overheated connections, open splices, or wire gauge mismatched to the breaker size.
Common fails:
- 14 AWG copper on a 20-amp breaker.
- Aluminum branch circuits terminated on devices not rated for AL or AL/CU.
- Open junction boxes or missing covers.
- NM cable exposed to damage where conduit is required.
Pro fix:
- Match breaker ampacity to conductor size.
- Use CO/ALR devices or proper AL/CU rated connectors where aluminum exists.
- Enclose all splices in listed junction boxes with covers.
- Replace backstabbed connections with screw-terminal terminations torqued to spec.
Real-world example: “He also fixed exposed, live wires in the attic and garage.” That is an instant fail avoided.
5) Insufficient or expired smoke and CO alarm protection
Life-safety devices are a must-have for a passing inspection. NFPA 72 recommends replacing smoke alarms at 10 years and CO alarms at end-of-life per manufacturer instructions. Most jurisdictions require smoke alarms in every bedroom, outside each sleeping area, and on every level. Colorado requires CO alarms in dwellings with fuel-burning appliances or attached garages.
Red flags:
- Missing alarms in bedrooms or on levels with sleeping areas.
- Mixed old and new units that cannot interconnect.
- Expired or chirping devices, or dead batteries.
Pro fix:
- Replace expired units and add missing coverage.
- Use interconnected alarms where required.
- Test monthly and replace batteries as directed.
From our site: “Detector Maintenance & Testing: Regular maintenance and testing of your detectors are essential for ensuring they function correctly. We provide ongoing maintenance services, including battery replacement and system testing, to keep your detectors in top condition.”
“We just hired Circuit Makers to replace and rewire our home smoke alarm system. Matt was very responsive... We will definitely be using Circuit Makers again.”
6) DIY splices, improper enclosures, and clearance violations
Quick fixes often lead to inspection failures. Inspectors look for professional workmanship and clear access.
Typical fails:
- Splices outside of boxes, taped connections, or wire nuts without boxes.
- Light fixtures and fans hung from non-rated boxes.
- Extension cords used as permanent wiring.
- Blocked panel working space, storage in front of the panel, or panels in closets.
Pro fix:
- Move all splices into listed junction boxes with covers.
- Replace non-rated boxes with fan-rated or fixture-rated supports.
- Restore panel clearances per NEC 110.26.
- Replace makeshift wiring with permanent cable or conduit.
Local note: In older basements and barns around the Eastern Plains, open splices and missing box covers are common. Inspectors do not pass them.
“Matt and crew were friendly and professional... flat rate up front... options for warranty and home electrical inspection... cleaned up the mess from cutting and drilling.”
7) No surge protection at the service equipment
Since the 2020 NEC, most new or replaced dwelling unit services must include a surge protective device (NEC 230.67). Lightning and utility events on the Plains can send damaging surges into homes. Without whole-home surge protection, inspectors can flag a deficiency during service upgrades or panel replacements.
Pro fix:
- Install a listed Type 1 or Type 2 whole-home surge protective device at the service or main panel.
- Add point-of-use surge protection for sensitive electronics.

Frequently Asked Questions
What commonly fails an electrical inspection?
Typical fails include missing GFCI or AFCI protection, overloaded or outdated panels, poor grounding and bonding, open splices, and expired smoke or CO alarms. Inspectors also flag blocked panel clearances and lack of surge protection on new or replaced services.
How can I prepare my home for an electrical inspection?
Clear access to the panel, attic, and mechanical areas. Replace dead batteries in alarms, test GFCI and AFCI devices, close all junction boxes, label circuits, and remove storage from in front of the panel. Fix visible hazards and schedule a pre-inspection check with a licensed electrician.
Do I need GFCI and AFCI in an older home?
Yes, when circuits are modified, extended, or replaced, current codes typically require GFCI and AFCI in designated areas. Even without renovations, adding protection greatly reduces shock and fire risk and helps you pass safety checks.
Are smoke and CO alarms required in every bedroom?
Smoke alarms are required in every bedroom, outside each sleeping area, and on every level. CO alarms are required in dwellings with fuel-burning appliances or attached garages. Replace smoke alarms at 10 years and follow manufacturer end-of-life for CO alarms.
Is whole-home surge protection required?
Since the 2020 NEC, new or replaced dwelling unit services typically require a surge protective device at the service equipment. It also protects sensitive electronics from lightning and utility surges.
In Summary
Most inspection failures trace back to life-safety devices, protection requirements, and panel issues.
