NEMA 5-15P to 5-15R Extension Cord with Inline GFCI Protection for Hazardous Environments

Why Choose Our NEMA 5-15P to 5-15R GFCI Extension Cord?

Standard extension cords offer no protection against electrical leaks. For OEM equipment builders and facility managers, an inline GFCI cord ensures compliance with outdoor and wet-location safety regulations.

Inline Ground Fault Circuit Interrupter (GFCI/PRCD)

The central molded module houses a highly sensitive current monitoring circuit. If it detects a difference in current between the hot and neutral wires (indicating a ground fault), it instantly breaks the circuit. This mechanism protects operators from fatal shocks when using equipment near water, damp concrete, or grounded metal plumbing.

The module includes a yellow TEST button to verify the safety circuit is functioning, and a red RESET button to restore power after a trip or test. An integrated power indicator light provides clear visual confirmation of live voltage.

Heavy-Duty 14AWG/12AWG Copper Conductors

Continuous commercial loads generate heat. We utilize thick 14AWG or 12AWG pure copper conductors to minimize voltage drop over extended cable runs. This allows high-draw equipment like pressure washers, air compressors, and heavy power tools to operate efficiently without premature motor burnout.

Weather-Resistant SJTW/SOOW Jacket

The outer jacket is extruded using specialized PVC or rubber compounds rated for outdoor use (SJTW or SOOW). It resists water penetration, UV degradation, and cracking in freezing temperatures, ensuring the cord remains flexible and safe across changing job site conditions.

Injection-Molded Housing and Strain Relief

The NEMA 5-15P plug, the NEMA 5-15R receptacle, and the GFCI module are all permanently sealed via injection molding. Extended strain relief ribs at every cable exit point distribute pulling tension, preventing the internal wiring from tearing loose during aggressive handling.

Complete Product Specifications

Buyer's Insight: Safety regulations often require GFCI protection for temporary outdoor power. By integrating the GFCI module directly into the extension cord, equipment manufacturers prevent end-users from bypassing safety protocols. This built-in protection significantly reduces liability risks associated with pressure washers and outdoor tools.

Professional Applications You Can Trust

For high-pressure cleaning equipment and pool pumps, water proximity creates constant shock hazards. The inline GFCI actively monitors the circuit and shuts down the pump instantly if water bridges an electrical connection, protecting the user standing on wet ground.

On construction sites, workers use heavy drills and saws while exposed to the elements. This GFCI extension cord provides a localized safety net, ensuring that a damaged tool housing or a frayed internal wire will not result in a fatal ground fault through the operator.

For industrial maintenance carts and portable heaters, facility managers require plug-and-play safety. The inline test and reset buttons allow technicians to verify protection before starting a task in damp basements or processing areas.

Advanced Safety Features

The GFCI module is designed to detect leakage currents (typically around 4-6mA) and interrupt the circuit in a fraction of a second. This rapid response time is critical for human safety.

The molded GFCI housing is designed to be weather-resistant for outdoor use, but it is not submersible. The module must be kept clear of standing water and direct heavy pooling to maintain internal circuit integrity.

Users must manually press the RESET button after the cord is plugged in or after a power outage, ensuring that connected machinery does not unexpectedly restart when grid power is restored.

Manufacturing Excellence

Our factory leverages [Years of Experience] years of experience in producing safety-critical power cords. Every GFCI assembly is subjected to 100% factory testing, including Hi-Pot dielectric withstand tests and automated GFCI trip-time verification. We maintain a strict [Defect Rate] defect rate and offer OEM CAD design support with a [Response Time] response time.

Frequently Asked Questions

Q: What do the Test and Reset buttons do?

A: The yellow TEST button simulates a ground fault to verify the module's internal circuitry is working. The red RESET button restores power to the receptacle after a successful test or an actual fault trip.

Q: Is this GFCI extension cord waterproof?

A: The cable jacket (SJTW/SOOW) is weather and water-resistant. The molded GFCI module is designed to withstand rain and outdoor moisture, but it is not rated for total submersion in water.

Q: Can the position of the GFCI module be customized?

A: Yes. For OEM orders, we can adjust the distance between the NEMA 5-15P plug and the GFCI module, as well as the length from the module to the female receptacle, to best fit your equipment design.

Q: What information is needed for a quotation?

A: Please provide the total cable length, GFCI module position, wire gauge, jacket type, trip threshold requirements, target certification, order quantity, and any custom packaging needs.

Custom Solutions for Your Business

Length and Module Placement: Define the exact total length and the placement of the GFCI block (e.g., closer to the plug or closer to the equipment) to optimize user access and keep the module off wet floors.

Wire Gauge and Jacket Selection: Choose 14AWG for standard 15A loads or upgrade to 12AWG for long-distance runs to prevent voltage drop. Select SJTW for standard outdoor use or SOOW for maximum oil and abrasion resistance.

Branding and Compliance Matching: Custom cable printing, warning labels, instruction tags, molded logos on the plug, and certification documentation can be tailored to match your specific market regulations.
