About 15A 125V NEMA L6-15P Twist-Lock Power Cords
Identifying a NEMA L6-15P plug compared to other 250v twist lock plugs.
The twist lock plugs are much harder to identify just by inspecting them, since they all have similar circular locking pins and only vary fractionally to prevent cross-plugging. To help the user with this, it is common for manufacturers to list the plug type on the face of the plug. Just for reference, here are the three most common NEMA L6 Plug types in comparison.
Extending an L6-15R receptacle with NEMA L6-15 extension cords.
In the event your equipment power supply cord cannot reach the L6 15r twist lock outlet, you will need to extend the power to the machine with a 250V 15A NEMA Twist Lock extension cable. We stock many lengths to help provide accessibility to power for our customers. Since you are not adapting the connector type, and the cable is the same rating as the power supply, this will have no functional drawbacks. Just make sure to route your cable in a location where it is safe from heavy foot traffic or sharp/heavy objects that could damage the cable.
Nema L6 15 plug to IEC 60320 connector 250v adapters.
The NEMA L6-15P is rated for 250 Volts and 15 Amps by itself, but the rating of the cord set will depend on the composition of the cable. Since the plug will be the connection to the power source, the power cable will be rated for 250 Volt, and the amperage will depend on the wire gauge since all of the IEC320 connectors utilized in this product line are at least 15 Amperes rated. If the cable utilizes at least 14awg wire, the cable will be rated for 15 Amps.

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.

About 15A 125V NEMA L6-15P Twist-Lock Power Cords
For this 250 Volt 15 Amp Twist Lock Product Line, we have connectors available with the IEC320 C13, C19, and NEMA L6-15R Extension cable. The standard wire gauge and jacket for this product line is Black SJT 14awg 3 Conductor. Since the amperage rating of almost all of the connectors and plugs is 15 Amperes, using 14awg for a standard wire gauge helps us stock more lengths and options for availability. These cables are commonly used where 250 Volts are readily accessible like a Data Center or industrial facility. The extra voltage reduces the amperage required for the same power output, and thus reduces the wire gauge of the cable which can be helpful in a high-density application.
Choosing the Right NEMA L6-15P Cord for Your Application
L6-15P to L6-15R — Extension and Whip Cords
Use an L6-15P to L6-15R cord when you need to extend a 250 V twist-lock circuit without changing the connector type. These are common in data centers where PDU outlets are fixed and equipment must be repositioned. Because the plug and receptacle ratings match, there is no derating of the circuit.
L6-15P to IEC C13 — PDU-to-Server Jumpers
The L6-15P to C13 configuration connects a 250 V twist-lock PDU outlet to servers, switches, routers, and other 1U/2U rack equipment with a C14 inlet. Running at 208 V instead of 120 V reduces current draw for the same wattage, which is why high-density racks favor this combination.
L6-15P to IEC C19 — High-Draw Equipment
The L6-15P to C19 cord feeds blade server chassis, large UPS units, and other equipment with a C20 inlet that draws more power than a C13 circuit can support. The C19 connector is rated for up to 20 A, making it the right choice when a single device approaches the 15 A circuit limit.

Frequently asked questions
- What is a NEMA L6-15P plug and what does it connect to?
- The NEMA L6-15P is a 3-wire, twist-locking male plug rated for 250 V AC and 15 A. Its two flat blades are angled so they lock into a matching NEMA L6-15R receptacle when rotated, preventing accidental disconnection. It is used on 240 V / 208 V two-pole, three-wire (hot-hot-ground) circuits common in data centers and industrial facilities.
- Where can I buy NEMA L6-15P power cords?
- World Cord Sets stocks 37 configurations of NEMA L6-15P cord sets — including L6-15P to L6-15R extension cords, L6-15P to IEC C13, and L6-15P to IEC C19 — ready to ship from East Windsor, CT. In-stock orders placed by 2:30 PM ET ship the same day. Custom lengths and non-standard configurations are also available; call (860) 763-2100 or submit a quote request.
- What voltage are NEMA L6-15P cords rated for?
- All NEMA L6-15P cord sets on this page are rated for 250 V AC. The plug itself is rated 250 V / 15 A, and every cord in this collection uses 14 AWG, 3-conductor SJT or SJTOW jacketing, which supports the full 15 A rating. These cords are intended for 240 V or 208 V circuits — not standard 120 V North American outlets.
- How do I tell a NEMA L6-15P apart from other 250 V twist-lock plugs?
- All NEMA L6-series plugs share a circular locking blade layout, so they look similar at a glance. Key identifiers for the L6-15P:Rated 15 A / 250 V (vs. 20 A for L6-20P or 30 A for L6-30P)Blade dimensions are unique to prevent cross-plugging with other L6 ratingsThe plug type is usually molded on the plug face by the manufacturerWhen in doubt, check the label on the plug face or match the receptacle label on your equipment.
