About Technology Research Corporation (TRC)

Technology Research Corporation (TRC), founded in 1981 and headquartered in Clearwater, Florida, has spent more than four decades engineering solutions that protect people, property, and equipment from the dangers of electrical shock and fire. As a publicly traded company (Nasdaq: TRCI), TRC has built a reputation as a recognized leader in portable electrical safety products serving consumer, commercial, marine, RV, and military markets worldwide.

At the heart of TRC's product portfolio is a patented ground fault detection technology that forms the basis for nearly everything the company makes. From marina docks to RV campgrounds to military field operations, TRC's innovations are engineered to detect dangerous electrical leaks and cut off power before catastrophic injury or fire can occur. Products are listed by Underwriters Laboratories (UL), approved by international safety standards bodies, and meet U.S. Government safety regulations — a testament to the engineering rigor TRC brings to every product category.

Flagship Product Lines

TRC is perhaps best known for its Fire Shield® technology — described as the world's smartest extension cord. The Fire Shield Extension Cord line responds to the critical threat of electrical fires caused by damaged or overloaded cords, automatically shutting off power when a fault condition is detected. It is a direct answer to safety standards outlined by the U.S. Consumer Product Safety Commission and a go-to solution for boaters, RV owners, and homeowners alike.

For marine and RV enthusiasts who rely on shore power connections, TRC's Shorepower Accessories and Electronic Surge Protectors are essential safeguards. The Surge Guard product line protects expensive onboard electronics and appliances from voltage spikes, power surges, and wiring faults that are common at campgrounds and marinas. These products are engineered specifically for the demanding environments that boats and RVs operate in, where electrical hazards can be especially dangerous.

TRC also expanded its offering into Hoses and cord management through its acquisition of the Shoreline Reel® product line — manual and motorized cord and hose reels designed for boats, recreational vehicles, and industrial applications. This addition made TRC a more complete solution provider for anyone managing power and utilities in the field.

Rounding out the lineup, TRC's Electrical Diagnostic and Repair Kits give professionals and serious DIYers the tools needed to identify and address electrical faults safely and accurately. These kits reflect TRC's broader mission: not just protecting against electrical hazards, but empowering users to understand and manage their electrical systems with confidence.

Military and Commercial Expertise

Beyond the consumer market, TRC has a deep history of supplying power monitoring and control equipment to the United States Military and its prime contractors, supporting tactical vehicles, naval vessels, and mobile electric generating systems. Since 1981, TRC has been a primary designer of electrical control and monitoring devices used in the Department of Defense's Mobile Electric Power Tactical Quiet Generating Systems (TQG) — a legacy of precision engineering that carries over directly into their commercial product quality.
