About NEMA 5-20P Power Cords
Designed for 20 Amp NEMA 5 20r receptacles, a common household power outlet.
The NEMA 5-20R Outlet is the second most common wall outlet in North America and is starting to become the standard for many homes in the United States. The NEMA 5-15P can also be connected into this outlet, however it will never draw more than 15 Amps of power. Devices that require more power will utilize these 5-20P Plug power cables.
Adapting 5-20r receptacle to a NEMA 30a twist lock.
If your device or equipment uses the 30A nema twist lock, L5-30 you can still access power from your 5-20R outlet but you will need an adapter cable. We offer these adapter cables to help our customers conveniently access power without having to hire an electrician to update the receptacle type. It is worth noting that Coverting a locking plug to a non-locking plug is not always advised as it generally removes a precautionary feature (secure power connection) put in place by the manufacturer.
NEMA 5-20 extension cables for extending power NEMA 5-20r outlet.
The Nema 5 20r receptacle can be extended using a NEMA 5-20p/r extension cable. We stock this product in many lengths in a black jacket color. In the even you require another length or color that is not available we can always help source the product you need.

The NEMA 5-20P is a 3 Wire grounded plug featuring two blades and one ground pin rated up to 125V AC and 20 Amps. The NEMA 5-20P is used in applications that require higher power draw such as large refrigerators, space heaters,large kitchen mixers, etc. The 5-20R T-SLot receptacle allows you to plug in either a 5-20P or a 5-15P plug, allowing greater flexibility. In modern home installations, 5-20R T-Slot receptacles are often used when 20A circuits are installed due to flexibility of being downward compatable with the 5-15P.

The IEC 60320 C13 is a grounded 3 Wire connector rated up to 250V and 15 Amps. The C13 mates with a C14 inlet, and is commonly used in a jumper cable scenario in IT Installations providing power from a PDU to a server, router, switch or other computing device. Most people know the C13 as 'the thing that plugs into my computer' because it is the standard connector used to power most desktop computers. In a desktop computer application, the most common cable is the NEMA 5-15P to C13, which connects your standard North American wall outlet to a desktop computer.

The IEC 60320 C19 is a grounded 3 Wire connector rated up to 250V and 20 Amps. The C19 mates with a C20 inlet, and is commonly used in a jumper cable scenario in IT Installations providing power from a PDU to a server, router, switch or other computing device. The C19 is typically used in high powered blade server chassis, large network routers, and other IT equipment that draws more power than a standard C13 can accommodate.

The IEC 320 C15 Power cable is used to power electrical devices that emit so much heat (intentionally or unintentionally) that they require a power connection that can withstand more than the 70 °C (158 °F) temperature rating of the standard C13. In combination with the C14 plug type, the use cases of this high-temperature cable are almost exclusively data center environments. This cable would most likely be found supplying a High-Powered Switch power from a rack-mounted PDU power supply source. If your equipment has a IEC320 C16 Inlet it should only be mated with the matching C15-Power Connector.

The NEMA 5-20P is a 3 Wire grounded plug featuring two blades and one ground pin rated up to 125V AC and 20 Amps. The NEMA 5-20P is used in applications that require higher power draw such as large refrigerators, space heaters, large kitchen mixers, etc. The cord feeds into the plug head in the direction of the ground pin, giving this a low profile when connecting to a wall outlet. This product is commonly used in applications with small space requirements.

About NEMA 5-20P Power Cords | 20A 125V Power Cables
General Information
The NEMA 5-20P Power Cords are a heavier duty version of the 5-15P, offering higher maximum power at 125V and 20A. If your equipment doesn't require more than 15A, the NEMA 5-15P Power Cords may be the better option to fit your power needs. This series of power cords are commonly used to connect a NEMA 5-20R wall receptacle to a variety of equipment and devices depending on your connection type. We offer NEMA 5-20P to IEC 60320 C13, C15, C19, extension cords, and OPEN/PIG TAIL/WHIPS.
What Is a NEMA 5-20P Power Cord?
What Is a NEMA 5-20P Power Cord?
A NEMA 5-20P power cord is a North American cord set with a 3-wire grounded plug rated for 125V AC and up to 20 Amps. The plug's distinguishing feature is one horizontal blade — this T-shaped blade pattern allows it to mate only with a NEMA 5-20R receptacle, while that same receptacle also accepts the more common 5-15P plug.
Because 20A circuits deliver up to 2,400 watts (vs. 1,875W on a 15A circuit), 5-20P cords are the standard choice for:
- PDU-to-device connections in data centers and server rooms
- High-draw IT equipment such as blade servers and large network switches
- Commercial kitchen appliances, space heaters, and other heavy-load devices
- OEM builds requiring a higher-capacity North American cord set
World Cord Sets stocks 5-20P cords in 12 AWG and 14 AWG SJT cordage, lengths from 1 to 50 feet, and connector options including IEC 60320 C13, C15, C19, NEMA 5-20R, and NEMA L5-30R. All configurations are UL- and cUL-listed and hi-pot tested before shipment.

Frequently asked questions
- What is the difference between NEMA 5-15P and NEMA 5-20P power cords?
- The key differences are current rating and blade shape:NEMA 5-15P — rated 15A/125V; both blades are vertical; fits any 5-15R or 5-20R outlet.NEMA 5-20P — rated 20A/125V; one blade is rotated horizontal; fits only a 5-20R outlet.If your equipment draws more than 15 amps or is rated for a 20A circuit, you need a 5-20P cord. If 15A is sufficient, a 5-15P cord will work in the same 5-20R outlet.
- Can I use a NEMA 5-20P cord as an extension cord?
- Yes. World Cord Sets offers NEMA 5-20P extension cords — these have a 5-20P plug on one end and a 5-20R connector on the other, allowing you to extend a 20A circuit while maintaining the full 20A rating. Available in 12 AWG SJT cordage to handle the full 20-amp load. Browse the dedicated extension cord collection for available lengths.
- What wire gauge should I choose for a 20-amp NEMA 5-20P cord?
- For a true 20A load, choose 12 AWG cordage. The 12 AWG SJT cords in this collection are rated for 20 amps and are the correct choice for equipment that draws close to the circuit maximum.14 AWG cords are also available with a 5-20P plug but are rated for 15 amps — suitable when the device draws 15A or less and the 5-20P plug is required by the outlet type.
- Are these NEMA 5-20P cords UL-listed?
- Yes. Every NEMA 5-20P cord set in this collection carries UL and cUL listings and meets RoHS requirements. Many configurations also carry REACH compliance. Each cord is hi-pot tested before shipment. Certification documentation is available from our sales team upon request.
