Server Technology PTCORD-L6 Locking C19 to 5-20P Power Cord

Overview

The PTCORD-L6 is a 10ft (3m) power whip from Server Technology built to connect rack PDUs and IT equipment with a locking IEC 60320/C19 connector on one end and a 5-20P straight-blade plug on the other. It's rated 20A and built with 12 AWG conductors, targeting data center and server room installs where a cord backing out of an outlet mid-shift is not an acceptable failure mode. PTCORD-L6 (often searched as PTCORD L6) is the locking-C19 variant in Server Technology's cord lineup, distinct from non-locking equivalents in the same family.

Key Features

• Locking IEC 60320/C19 connector: the C19 end locks into a compatible PDU outlet, so vibration, cable weight, or an accidental tug in a packed rack doesn't pull the cord loose and drop power to connected gear.
• 5-20P straight-blade plug: terminates into a standard NEMA 5-20P 20A receptacle, giving you a direct path from wall or rack-mounted 20A circuits without an adapter.
• 20A current rating: matches the higher end of common 120V rack circuits, so this cord can carry more sustained load than a standard 15A whip before you need to worry about derating.
• 12 AWG conductors: heavier gauge than the 14-16 AWG found on lighter-duty cords, which keeps voltage drop and heat down when running at or near the 20A rating over the full 10ft run.
• 10ft (3m) length: enough reach to route from a PDU at the top or bottom of a rack down to a floor receptacle, or between adjacent rack positions, without splicing or an extension.
• cULus approval: listed to UL and CSA safety standards, which is typically a requirement for passing electrical inspection in commercial data center builds.

Integration & Compatibility

Use the PTCORD-L6 as the whip between a rack PDU's locking C19 output and a 20A 5-20R wall or floor receptacle. It pairs naturally with Server Technology rack PDUs and other equipment exposing a locking C19 input. If you're specifying PDU whips for a new rack build, a rack PDU sizing and selection guide is worth reviewing alongside this cord to confirm circuit and connector matching before order. For racks where the branch circuit terminates in a twist-lock rather than a straight-blade receptacle, check the same family for a twist-lock variant instead of forcing this cord with an adapter.

Frequently Asked Questions

Q: What connector does the PTCORD-L6 use on the PDU side?

A: A locking IEC 60320/C19 connector, which mechanically locks into a compatible C19 inlet to resist accidental disconnection.

Q: What's the current rating on the PTCORD-L6?

A: 20A, matching the 5-20P plug end and 12 AWG conductor sizing.

Q: How long is the PTCORD-L6 power cord?

A: 10ft (3m).

Q: Is the PTCORD-L6 safety listed?

A: Yes, it carries cULus approval.

Q: What wire gauge does the PTCORD-L6 use?

A: 12 AWG.

Marty Allison

The PTCORD-L6 is a straightforward spec once you know what's on each end: locking C19 into 5-20P, 20A, 12 AWG. I get asked about this cord mostly by people replacing a whip that walked out of its PDU outlet during rack work — the locking C19 is the fix for that specific problem.

Technical Highlights:

• Locking C19 connector: mechanically retains the connection at the PDU end, which matters most in racks with frequent cable moves or dense cable management pulling on the whip.
• 20A / 12 AWG pairing: the conductor gauge is sized to the 20A rating rather than undersized like you'll see on cheaper 15A-rated cords repurposed at 20A — less voltage drop over the 10ft run.
• 10ft length: long enough to route from a top-of-rack PDU down to a floor receptacle in most standard rack heights without needing a second cord or extension.

Deployment Considerations:

• Confirm your branch circuit receptacle is a 5-20R before ordering — this cord's plug end is straight-blade 5-20P, not twist-lock, so it won't seat in a L5-20R twist-lock outlet.
• Minimum order quantities can apply on PDU accessory cords like this one; confirm order quantity before finalizing a rack build-out.

Specify the PTCORD-L6 when you're wiring a rack PDU to a 20A straight-blade circuit and want the PDU-side connection locked down — typical in colocation cages and data center rows where techs are in and out of the rack regularly.
