WELLONG GFCI Replacement Plug 15A 120V — 3-Prong Compact Safety Plug with Test/Reset, UL-Certified

The WELLONG Replacement GFCI Plug is a UL-listed 15A, 120V three-prong safety device that quickly cuts power (≤0.03s) on ground-faults to protect people and appliances.

This compact replacement plug is built to add ground-fault circuit interruption to ordinary three-prong cords and hardwired appliance connections. Rated for 15 amps and 120 volts AC, it responds to leakage currents as small as 6 mA and trips in under 30 milliseconds. The unit meets UL943, 498, and 746C standards and offers a simple screw-terminal installation for common home equipment and power tools.

How does this GFCI plug stop electric shock risks?

The device continuously compares current between the live and neutral conductors and opens the circuit instantly when a difference (leakage) is detected. That rapid action — within 0.03 second — helps reduce the chance of harmful current flowing through a person or stray path. It also resets automatically once the fault clears.

• Residual current sensitivity: 6 mA for fast detection of small leakages.
• Trip speed: under 30 milliseconds to interrupt hazardous paths.
• Voltage withstand rating: 6000V for robust insulation performance.
• UL-certified to recognized safety standards (UL943, 498, 746C).

Which appliances and tools can I use it with?

This replacement GFCI plug is designed for a wide range of household and light-commercial equipment that normally uses a three-prong connection. It’s suitable for devices where added ground-fault protection is desirable, such as pumps, heaters, kitchen appliances, power tools, and more. Always follow the appliance manufacturer’s wiring guidance and local electrical codes.

• Common uses: pressure washers, pool pumps, water heaters, hair dryers.
• Heavy-duty: electric drills, washing machines, ovens, radiators (within 15A/1800W limit).
• Not for direct connection to circuits exceeding 15 amps or 120V supply.
• Intended for replacement of standard three-prong plugs with GFCI protection.

How do I install, test, and maintain this replacement plug?

Installation requires connecting three wires to clearly marked screws: black = live (L), white = neutral (N), and green = earth (E). After tightening terminals and securing the cover, verify operation with the integrated TEST and RESET buttons before regular use. Periodic testing helps confirm continued protection.

• Wiring: screw terminals labeled black (L), white (N), green (E).
• Initial test: press TEST — indicator should go off; press RESET — indicator should light.
• Routine: test monthly or per local electrical recommendations.
• Maintenance: keep dry, replace if mechanically damaged or if tests fail.

What electrical limits and certifications should I be aware of?

The WELLONG GFCI plug is rated for 120V AC at 60Hz and a maximum continuous current of 15 amps (approx. 1800 watts). It has passed endurance testing and carries UL listings for safety and construction compliance. Do not exceed the specified voltage or current ratings.

• Rated voltage/current: AC 120V, 60Hz; 15A maximum (1800W).
• Residual current trip: 6 mA; tripping time ≤ 30 ms.
• Safety approvals: UL943, UL498, UL746C and UL Listed product.
• Durability: endurance test cycles performed to industry limits.

Who is this for: Homeowners, handymen, and service technicians who want to add or restore GFCI protection to three-prong cords and appliances without rewiring a circuit. It’s ideal for protecting outdoor equipment, wet-area devices, and workshop tools that operate within a 15A, 120V envelope. If you need higher amperage protection, a different GFCI rated for that load or a hardwired GFCI device should be chosen.
