About IEC C20 to Saf-D-Grid 400V Power Cords
Superior Power Density of the Anderson Saf-D-Grid to IEC320 C20 Cables
With power density becoming increasingly important as data center equipment becomes more capable and hungrier for power, Anderson delivered a new spin on the standard data center power connection. The standard IEC 60320 plug and connector standards are limited to a voltage of 250 Volts. These Anderson Saf-D-Grid connectors are rated for up to 400V and are the same size as the IEC 60320 connector bodies.
Saf-D-Grid Cables General Usages
These power cables are generally used in Data Centers for powering Cisco, Nexus and Arista rack-mounted equipment like servers, switches and power supply units. The unique keying configuration prevents the connection of 400v to 300v and a short connection of male to male. The recessed power connection points are a substantial safety feature as they shield the connection point, effectively shrouding any potential arc during unplugging under load.

On 21 of the cords here
The IEC 60320 C20 is a grounded 3 Wire Plug rated up to 250V and 20 Amps. The C20 mates with a C19 outlet, typically found on Data Center/IT specific PDUs (Power Distribution Unit). The most common configuration for a C20 is in a jumper cable scenario, providing power from a PDU to a blade server chassis, high powered server, large network router, or similar device.

The Saf-D-Grid 400V Connector is rated for 400VAC and 16 Amps of power. It mates with the matching Saf-D-Grid 400V Inlet located on various data center equipment. This is the highest power rated connector for the footprint of an IEC 60320 connector.

About IEC C20 to Saf-D-Grid 400V Power Cords
These power cords are generally used to power switches, power supply units and routers in a data cabinet. These high power connectors have recently become increasingly popular because of their rigid connector body and superior material composition allowing for much higher power output in the same profile. The C20 plug can access power from a standard rack-mount PDU located in a typical data rack cabinet.
Choosing the Right C20 to Saf-D-Grid 400V Cord
Match Amperage to Your Equipment
These cords come in two current ratings. Verify the amperage on your equipment's PSU nameplate before ordering:
- 16A / 14 AWG — standard choice for most Cisco Nexus switches and PSUs rated at or below 16 amps.
- 20A / 12 AWG — required for higher-draw PSUs and any circuit protected by a 20A breaker.
Color Coding for Cabinet Management
Blue and red variants are available alongside black. Many data center teams use color to distinguish power feeds — for example, blue for utility A-side and red for utility B-side — reducing mis-patching during maintenance. All three colors carry identical electrical ratings.
Cordage Type: SJT vs. H05VV-F
Most cords in this collection use SJT cordage, the North American standard for data center environments. A subset uses H05VV-F, a European harmonized cordage suitable for international deployments. Both are UL-listed on the applicable SKUs. If your installation requires a specific approval mark (CCC, cUL, RoHS, REACH), filter by certification or check the individual product page.

Frequently asked questions
- What is the Anderson Saf-D-Grid 400V connector and why is it used in data centers?
- The Anderson Saf-D-Grid 400V is a keyed power connector rated for up to 400VAC — double the 250V ceiling of standard IEC 60320 connectors — while occupying the same physical footprint. Data centers use it to deliver higher power density per rack unit without changing cabinet layouts. Recessed contact points shroud live connections, reducing arc risk when unplugging under load. The keying prevents accidental mating of 400V and 300V equipment.
- What equipment uses a Saf-D-Grid 400V inlet?
- Saf-D-Grid 400V inlets are found on rack-mounted data center equipment including:Cisco Nexus 5000 series routers and switchesCisco Nexus 9000 switchesNexus power supply units (PSUs)Arista rack-mounted switches and serversThe C20 plug on the other end connects to a standard rack PDU C19 outlet, making these cords a direct PDU-to-device jumper.
- What is the difference between the 16A and 20A versions of these cords?
- Both versions use a C20 plug and a Saf-D-Grid 400V connector, but differ in wire gauge and current capacity:16A cords use 14 AWG cordage and are suited for equipment drawing up to 16 amps.20A cords use 12 AWG cordage and support loads up to 20 amps.Check your equipment's PSU nameplate or spec sheet for the required amperage before ordering. All cords on this page are rated for 250V and are UL-listed.
- Are these cords available in custom lengths or colors?
- Yes. Standard lengths range from 1.0 to 4.5 meters, and cords are stocked in black, blue, and red. Custom lengths and non-standard colors are hand-terminated at the Connecticut facility. Call (860) 763-2100 or submit a quote request with your specifications. Lead time is typically 3–4 business days from in-stock components.
