Educational articles answering the electrical questions we hear most often from commercial property owners, facility managers, and business operators.
A tripping breaker is a symptom, not the problem. The three most common causes are overloaded circuits, short circuits, and ground faults — each with a different diagnostic approach and solution. Here's how to tell them apart.
Flickering lights in a commercial building can indicate loose connections, voltage fluctuations, or overloaded circuits. Some causes are minor — others signal a serious problem developing in the electrical system.
GFCI protection is required by code in wet and damp locations. Understanding how GFCIs work — and why they sometimes trip without an obvious cause — helps facility managers respond appropriately instead of simply resetting and moving on.
Electrical panels don't last forever. Signs that a panel upgrade may be needed include frequent breaker trips, double-tapped breakers, a panel over 25 years old, or a facility that has added significant electrical load since the original installation.
Voltage surges — from utility switching, lightning, or large motor starts — can damage sensitive equipment and shorten the life of electrical components. Whole-facility surge protection is one of the most cost-effective investments a building owner can make.
Smoke detectors have a finite service life — typically 10 years. In commercial buildings, interconnected systems require periodic testing, battery replacement, and eventual device replacement. Here's what a proper maintenance schedule looks like.
