Electrical Code Compliance for Oklahoma Businesses: Common Mistakes to Avoid

For any business operating in Oklahoma—whether it’s a retail storefront, manufacturing facility, or oilfield operation—electrical code compliance isn’t optional. It’s a critical part of running a safe, efficient, and legally sound operation.

Unfortunately, many businesses don’t realize they’ve violated code until something goes wrong—like a failed inspection, equipment failure, or worse, a workplace accident. In this post, we’ll cover the importance of electrical code compliance, the most common mistakes businesses make, and how to prevent them.

Why Electrical Code Compliance Matters

The National Electrical Code (NEC), updated every three years, sets the standard for safe electrical design, installation, and inspection. While adopted at the national level, it’s also enforced at the state and local level, including throughout Oklahoma.

Compliance isn’t just about passing inspections—it’s about protecting:

• Your employees from electrical hazards

• Your facility from fires or outages

• Your business from fines, insurance issues, and operational delays

At Houston Electric, we’ve helped businesses across Oklahoma—from Enid to Garber and beyond—navigate compliance with confidence.

Common Electrical Code Mistakes (and How to Avoid Them)

1. Improper Grounding

Improper or inadequate grounding is a frequent violation. It can result in unsafe power surges, shock hazards, and poor equipment performance.

How to avoid it:
Have a qualified commercial electrician inspect your system for proper bonding and grounding per NEC Article 250.

2. Overloaded Circuits

Trying to power too many devices or machines on a single circuit can lead to overheating and fire risks.

How to avoid it:
Ensure circuits are properly sized for the load they’re supporting. An electrical load analysis can prevent long-term issues.

3. Inadequate Labeling of Panels and Breakers

Code requires electrical panels and breakers to be clearly labeled. This is essential during maintenance or emergencies.

How to avoid it:
Review panel labeling annually and update whenever new circuits are added or removed.

4. Exposed Wiring

Whether in office ceilings or warehouse walls, exposed wiring is both a code violation and a major safety concern.

How to avoid it:
Use approved conduit or raceways to protect all wiring in accessible or exposed areas.

5. Improper Use of Extension Cords

Extension cords are not a substitute for permanent wiring. Relying on them long-term can lead to code violations and fire hazards.

How to avoid it:
If you need more outlets, have them professionally installed by a licensed electrician.

6. Lack of GFCI or AFCI Protection

GFCI (Ground Fault Circuit Interrupters) and AFCI (Arc Fault Circuit Interrupters) are required in specific locations, such as kitchens, bathrooms, or outdoor areas.

How to avoid it:
Ensure all applicable outlets meet NEC requirements for GFCI or AFCI protection. This is especially important in environments with moisture or high electrical usage.

7. Non-Compliant Panel Access

Electrical panels must have 30 inches of clear space side-to-side and 36 inches in front. Storage or obstructions in front of panels is a common violation.

How to avoid it:
Keep all panels clear and accessible. Regular safety walk-throughs can help catch violations early.

8. Outdated Systems or Retrofitting Without Permits

Upgrading your electrical system without a permit or inspection often leads to serious code violations.

How to avoid it:
Always work with a licensed commercial contractor like Houston Electric who pulls the correct permits and ensures full compliance.
