Electrical codes exist to ensure safety and consistency in residential and commercial buildings. These standards help prevent fires, electrocution, and other hazards caused by faulty wiring and improper installations. However, whether due to outdated systems, DIY mistakes, or rushed contractor work, code violations are surprisingly common—especially in older homes or during renovations.
At CGA Electric, we frequently encounter electrical issues that not only pose serious safety risks but also violate the National Electrical Code (NEC). In this post, we’ll highlight the top 7 most common electrical code violations and offer advice on how to correct them properly and safely.
1. Improper Grounding
The Problem: Grounding provides a safe path for electrical currents to follow in the event of a fault or short circuit. Without it, you’re at risk of electric shock or even fire. Common grounding violations include missing grounding conductors, improperly bonded panels, or lack of ground rods.
The Fix: Correct grounding requires identifying all circuits that are ungrounded and installing proper grounding conductors. For service panels, ensure ground rods are properly driven and bonded. A licensed electrician can test your grounding system for compliance and make necessary updates.
2. Overcrowded Electrical Boxes
The Problem: Electrical boxes must provide enough room for the number of wires and devices they contain. Overcrowding can lead to overheating, short circuits, or wire damage. Each box has a volume rating, and cramming too many wires inside is a clear code violation.
The Fix: Calculate the box fill using NEC guidelines, which take into account the number of wires, devices, and clamps. If your box is too small, replace it with a larger one or install an additional box to distribute the wiring more safely.
3. Incorrect Breaker Sizes
The Problem: Circuit breakers must be correctly matched to the wire size and load they are protecting. An oversized breaker may not trip in time to prevent overheating, while an undersized one may trip unnecessarily. This is especially problematic with HVAC units, water heaters, and high-powered appliances.
The Fix: Check the wire gauge for each circuit and ensure the breaker is appropriately rated. For example, 14-gauge wire should have a 15-amp breaker, while 12-gauge wire requires a 20-amp breaker. An electrician can evaluate your panel and make safe, code-compliant adjustments.
4. Missing GFCI or AFCI Protection
The Problem: Ground Fault Circuit Interrupters (GFCIs) and Arc Fault Circuit Interrupters (AFCIs) are required by code in specific areas of the home. GFCIs protect against shock in wet areas like bathrooms and kitchens, while AFCIs guard against electrical fires in living spaces. Many older homes lack this protection.
The Fix: Install GFCI outlets or breakers in bathrooms, kitchens, garages, basements, and outdoor locations. AFCI breakers are now required for most living areas and bedrooms. A licensed electrician can upgrade your panel and circuits to include both GFCI and AFCI protection where needed.
5. Non-Accessible Splice Boxes
The Problem: Splices, or wire connections, must always be housed in an accessible junction box with a cover. Hiding splices behind drywall, in ceilings, or under floors is a major code violation and a serious fire risk.
The Fix: Locate all hidden splices and install approved electrical boxes with cover plates. Make sure the boxes are easily accessible for future inspections or repairs. This usually requires cutting into drywall and patching afterward, which is best handled by a professional.
6. Improperly Secured Wiring
The Problem: Wiring must be secured properly to framing members to prevent sagging, abrasion, or strain on terminals. Common violations include loose cables, wires stapled too tightly, or cables hanging across joists unsupported.
The Fix: All NM (non-metallic) cable must be secured within 12 inches of a box and every 4.5 feet along the run. Use approved cable staples or straps, ensuring they are snug but not crushing the wire. Reroute and secure any wiring that doesn’t meet these guidelines.
7. Failure to Use Wire Connectors and Proper Enclosures
The Problem: Simply twisting wires together and covering them with tape is not only a code violation—it’s extremely dangerous. All wire connections must be made using the proper connectors and enclosed in a box that’s rated for the environment.
The Fix: Use UL-listed wire nuts or push-in connectors for all splices. Install a junction box to house the connections, and always secure the box with a cover. In wet or outdoor areas, use weatherproof boxes and fittings rated for exterior use.
Why Fixing Code Violations Matters
Ignoring or being unaware of code violations can have serious consequences:
- Fire Hazards: Faulty wiring is one of the leading causes of residential fires.
- Electric Shock Risk: Poor grounding and missing GFCI protection can lead to dangerous shocks.
- Insurance Issues: Insurance may not cover damage or injury caused by unpermitted or code-violating electrical work.
- Failed Inspections: Whether you’re selling your home or pulling a permit for renovations, code violations can delay projects and cost more to fix later.
