Nema 15 Amp to 20 Amp Plug Adapter

This compact power adapter converts a standard NEMA 5-15P male plug (common 15A, 3-prong grounded household plug used in North American 120V outlets) to a NEMA 5-15/20R female receptacle (20A T-blade or T-slot outlet, compatible with both 15A and 20A plugs). It’s designed for safely connecting devices with 20A T-blade plugs—such as high-power appliances, tools, or extension cords rated for 20A—to a standard 15A wall outlet without needing a full replacement cord. The ETL Listed certification (from Intertek) confirms it meets rigorous safety standards for electrical shock, fire prevention, and grounding, equivalent to UL approval. Ideal for home garages, workshops, kitchens, or offices where you need to “upgrade” a 15A outlet temporarily for 20A equipment, but remember: the overall rating is limited to 15A due to the input plug.Key Use Case: If your device has a NEMA 5-20P plug (T-shaped hot blade for 20A circuits), this adapter lets it draw power from a 15A NEMA 5-15R wall socket. However, it cannot provide more than 15A—exceeding this risks overheating the adapter or tripping breakers.

Technical Specifications:

  • Male: NEMA 5-15P (3-prong grounded, 15A/125V plug)
  • Female: NEMA 5-15/20R (T-blade/T-slot receptacle, accepts 15A or 20A plugs)
  • Electrical Rating: 15A maximum (input limit; receptacle supports up to 20A, but do not exceed 15A total load)
  • Safety Standards: ETL Listed per applicable UL standards.
  • Housing Material: Flame-Retardant PC/ABS Alloy (94V-0 Rated).
  • Contact Material: High-Current Copper Alloy with Silver Plating.

Power Adapter Applications:

  • Office Environments: Power multiple devices from a single 20-amp circuit
  • Workshops & Garages: Adapt 20-amp outlets for standard tool usage
  • Data Centers: Connect 15-amp equipment to 20-amp PDU outlets
  • Home Theater Setup: Power audio/video equipment from dedicated 20-amp circuits
  • Kitchen Applications: Use small appliances on 20-amp kitchen circuits
  • Commercial Spaces: Adapt specialized 20-amp outlets for general use

Important Usage Notes:

  • Circuit Capacity Warning: This adapter does not increase the circuit capacity. The total load connected to the adapter must not exceed 15 amps, even when plugged into a 20-amp circuit.
  • Proper Installation: Ensure the wall outlet is properly grounded before use
  • Load Management: Do not exceed the 15-amp/1875-watt maximum rating of the adapter
  • Single Use: Do not daisy-chain multiple adapters or power strips
  • Inspection: Regularly check for signs of overheating or damage during use
  • Outlet Compatibility: Only use with properly installed 15-amp or 20-amp grounded outlets
