Common Hidden Electrical Risks in Older Commercial Buildings and How to Mitigate Them
Many commercial buildings in North Alabama and Southern-Middle Tennessee have stood the test of time. They may have solid structures and timeless design, but their electrical systems often tell another story. Wires, panels, and outlets tucked behind walls can hide problems that put safety, efficiency, and compliance at risk. At Stewart Electric Company, Inc., we regularly work with building owners and facility managers to identify these hidden hazards and bring older systems up to modern standards.
Why Older Electrical Systems Can Be a Problem
Buildings built decades ago were not designed for the electrical demands of today’s world. In the past, office spaces had fluorescent lighting and a few computers. Today, those same buildings may power hundreds of devices, complex HVAC systems, automated machinery, and charging stations. When older wiring and panels are pushed beyond their limits, they can overheat or fail unexpectedly.
Some of the most common hidden issues in aging buildings include:
- Circuits that frequently overload or trip breakers
- Warm or buzzing electrical panels
- Outdated fuse boxes still in use
- Brittle or deteriorating insulation on wiring
- Outlets without proper grounding or GFCI protection
- Old aluminum wiring that no longer meets code
These issues often remain unnoticed until a major failure happens. Even if lights turn on and equipment runs smoothly, that doesn’t mean the electrical system is safe.
How Electrical Codes Have Changed
Electrical safety codes are updated every few years to improve protection and efficiency. Many older systems simply haven’t kept up with these changes. The National Electrical Code (NEC) now includes requirements for better grounding, arc fault protection, and safer breaker panels.
For example, outlets near sinks, break rooms, and outdoor areas must now include GFCI protection to prevent electrical shock. Older panels might also lack the capacity to handle today’s power loads or meet grounding standards. When a system hasn’t been inspected or updated in decades, it’s likely out of compliance and could pose safety concerns.
Warning Signs You Shouldn’t Ignore
If your commercial property is more than 20 years old, it’s worth scheduling a professional inspection, especially if you notice:
- Lights that flicker or dim when equipment starts
- Outlets that feel warm or show discoloration
- Breakers that trip without clear reason
- Sudden increases in energy bills
- Buzzing or humming sounds near panels
These may seem like minor annoyances, but they can signal deeper problems. A qualified commercial electrician can evaluate your system with load testing, visual inspections, and thermal imaging to find areas of concern before they lead to outages or damage.
Updating Older Systems Without Breaking the Budget
Upgrading an older electrical system does not have to mean a full replacement. In many cases, Stewart Electric helps businesses modernize their systems in phases to control costs and reduce downtime. Some of the most effective improvements include:
Panel Replacement:
Installing a new panel increases safety, capacity, and reliability. It also helps ensure compliance with current electrical codes.
Targeted Rewiring:
Instead of rewiring an entire building, we identify and replace only the circuits or sections that pose the greatest risk.
Improved Grounding and Bonding:
Proper grounding protects both equipment and personnel from electrical shock and power surges.
Energy-Efficient Lighting:
LED upgrades reduce overall power demand and heat output, which helps older systems run more efficiently.
Preventive Maintenance:
Routine inspections, cleaning, and testing can extend the life of your electrical components and prevent costly emergencies.
