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 compatible with the 5-15P.
What does a NEMA 5-20P Connect to?
The NEMA 5-20 Plug connects to both the NEMA 5-20R Connector and the NEMA 5-15/5-20R Wall Outlet. The connector is commonly found on Extension cords, and the NEMA 5-15/5-20R Wall Outlet is the standard power supply outlet in all residential and commercial construction in North America.
The NEMA 5-20P to Open/Whip/Pig Tail- NACC is a power supply cord rated for 125VAC and 20A max. NACC, North American Color Code, refers to the color code of the conductor insulation which is BLACK / WHITE / GREEN. This cord is for field installation to equipment or device that requires a line, neutral and ground conductor (not exceeding the rated power of the cord) to operate. Standard Whips are Removed Outer Jacket(ROJ) 2" and then each conductor is stripped 1/4" to bare conductor. Other ROJ/Strip combinations are available for bulk quantities upon request.
The NEMA 5 standard specifies three wire (hot-neutral-ground), two blade one ground pin, grounded devices. The NEMA 5-20P is a 3 Wire grounded plug featuring two blades (one horizontal and one vertical) and one ground pin rated up to 125V AC and 20 Amps. This is do not allow a 5-20P into a 5-15R, but to allow a 5-15P (plug) into a 5-20R (t-slot receptacle).
The open end of a power supply cord is hard wired to another device, providing power either to our from that device. Unless otherwise noted, our power supply cords come standard with a 2" ROJ (Remove Outer Jacket) and a 1/4" Strip. The ROJ length determines the length of the individual conductors, and the Strip length determines the amount of copper exposed on the end of each conductor. If you require a custom ROJ or Strip length, please don't hesitate to reach out to us.
International Color Code(ICC) vs. North American Color Code(NACC)
For the majority of our customers, the color code used for the cordage is negligible. However, for OEM customers, or customers dealing with government installations or projects that have highly specified cords the color code used will be important to establish. Our standard color code for our Cut/ Remove of Outer Jacket/ Strip Conductor Job is North American Color Code (NACC).
|Ground Color||Neutral Color||Line/ Hot Color|
|International Color Code (ICC)|
Green & Yellow
|North American Color Code (NACC)||Green||White||Black|
